Find the slope of the line that passes through the pair of points (-1,-9) and (-3,10)
Answer:
-9.5
Step-by-step explanation:
The slope (m) is the ratio of the change in y to the change in x:
m = (y2 -y1)/(x2 -x1)
m = (10-(-9))/(-3-(-1)) = 19/-2
m = -9.5
The slope of that line is -9.5.

What additional information is needed to prove the triangles are congruent by ASA?
Answer:
The additional information that needed is m∠ABD = m∠CDB ⇒ C
Step-by-step explanation:
In the given figure
Triangles ADB and CBD are congruent by ASA under these conditions
m∠ADB = m∠CBDDB = BD ⇒ the side joining the congruent anglesm∠ABD = m∠CDBLet us see the given to find the correct answer
∵ ∠ADB and ∠CBD have the same mark
∴ m∠ADB = m∠CBD ⇒ (1) given
∵ Side DB is a common side in the two triangles
∴ DB = BD ⇒ (2) given
∵ ∠ABD and ∠CDB are the angles at the end of BD
∴ m∠ABD must equal m∠CDB ⇒ (3) to prove the congruency using ASA
∴ The additional information that needed is m∠ABD = m∠CDB
Answer:
To prove that two triangles with three congruent, corresponding angles are congruent, you would need to have at least one set of corresponding sides that are also congruent. You could then use ASA or AAS congruence theorems or rigid transformations to prove congruence.

Which graph shows h(x) = (f(x))(g(x))?
Hi! I'd be happy to help you. However, there is not enough information here for us to help, as there is no way to tell which graph is correct without the equations of f(x) and g(x). They'd look something like:
"f(x) = x-2," or "g(x) = 7x+3."
Are you able to provide the equations of of f(x) and g(x)? I would be more than happy to help.
----------------------------------------------------------------------------------------------------------------
UPDATE: I did not realize that you could solve this problem without the original equations. Please refer to the other user's response for an amazing and detailed explanation of this problem! :)
Answer:
The first graph.
Step-by-step explanation:
We want to find the graph that shows:
[tex]h(x)=f(x)g(x)[/tex]
Notice that g(x) is a line and f(x) is a quadratic.
So, their product must be a cubic.
Also, g(x) and f(x) is the same across all four graphs. The only difference is h(x).
Notice that our quadratic f(x) is curving upwards. Therefore, the leading coefficient of f(x) is positive.
Notice that the line g(x) is sloping downwards. Therefore, the leading coefficient of g(x) is negative.
So, this means that the leading coefficient of our cubic h(x) must be negative since a positive times a negative yields a negative.
Remember that the parent cubic function has a positive leading coefficient and it rises from left to right.
So, if our leading coefficient is negative, the cubic will fall from left to right.
Therefore, we can eliminate the 2nd and 3rd graphs since in those two, h(x) has a positive leading coefficient.
Now, we can just pick a test point and determine whether our graph is the first or the fourth.
Let's let x = -2. So, we have the equation:
[tex]h(x)=f(x)g(x)[/tex]
Substitute all Xs for -2s:
[tex]h(-2)=f(-2)g(-2)[/tex]
Looking at the graphs, we can see that f(-2) is 8. g(-2) is 0.5. Substituting this back, we get:
[tex]h(-2)=8(.5)=4[/tex]
So, h(-2) should be 4.
For the first graph, h(-2) is indeed 4.
For the second graph, h(-2) is 6.
So, the correct graph that represents f(x)g(x) is the first graph.
And we're done!
What are the measures of each interior and exterior angles of regular quadrilateral MNOP?
Answer:
A regular polygon is a polygon that is equilateral and equiangular.
The only regular quadrilateral is the square.
We know that all the interior angles of a square are 90° each, so we are fine with that.
Now, for the exterior angles.
If we fix our position in the vertex, we can do from one side, to the same side, a full rotation of 360°.
Now, if we only do an external rotation, this means, from one side to other side, we will do a rotation of 360° minus the interior angle:
this is:
360° - 90° = 270°
Below is an image as a guide of this.

Duke Energy reported that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio was $104 per month (Home Energy Report, Duke Energy, March, 2012). A researcher believes that the cost of electricity for a comparable neighborhood in Chicago, Illinois is higher. A sample of homes in this Chicago neighborhood will be taken and the sample mean monthly cost of electricity will be used to test the following null and alternative hypotheses.
Assume the sample data lead to rejection of the null hypothesis.
What would be your conclusion about the cost of electricity in the Chicago neighborhood?
The input in the box below will not be graded, but may be reviewed and considered by your instructor. What is the Type I error in this situation?
The Type 1 error in this situation What are the consequences of making this error?
The input in the box below will not be graded, but may be reviewed and considered by your instructor. What is the Type II error in this situation?
Answer:
When the null hypothesis is rejected
The conclusion is that there is enough evidence to support the claim of the researcher
When a type I error occurs
The consequences is that the conclusion that there is enough evidence to support the claim of the researcher is actually incorrect
When a type II error occurs
The consequences is that the conclusion that there is enough evidence to support the claim of the researcher is actually correct
Step-by-step explanation:
From the question we are told that
The cost of electricity per month is [tex]\mu = \$104[/tex]
The null hypothesis is [tex]H_o : \mu = \$104[/tex]
The alternative hypothesis is [tex]H_o : \mu > \$104[/tex]
Generally if the null hypothesis is rejected then the conclusion would be that there is enough evidence to support the claim of the researcher
Generally a Type I error is a an error that occurs when the null hypothesis is incorrectly rejected
So in the case of this question the consequence of making this type of error is that the conclusion that there is enough evidence to support the claim of the researcher is actually incorrect
Generally a Type II error is an error that occurs when the null hypothesis is incorrectly not rejected
So in the case of this question the consequence of making this type of
error is that the conclusion that there is enough evidence to support the claim of the researcher is actually correct

Olivia buys 4 masks that each cost the same amount and a scarecrow. She spent a total of $176.75. If the scarecrow costs $56.75, write an equation she can use to find the cost of each mask. * 10 points 4m + 56.75 = 176.75 5m + 56.75 = 176.75 4m - 56.75 = 176.75 5m - 56.75 = 176.75
4m+56.75=176.75
Solve the equation to find the cost of each mask.
Ramona believes that plants exposed to radio waves will become extra tall. She decides to plant two
seeds in 20 separate pots. She placed 10 pots near a radio for 5 days and the other 10 pots in a room
without a radio. Each plant had the same size pot and the same amount of soil and water She
compared the height of the exposed plants to those not exposed. The average height of the plants
exposed to the radio waves was 6.5 cm. The average height of the plants unexposed was 70 cm
Answer:I have this same problem but if you’re asking for the independent and other questions here’s the answer. Independent variable is the radio since that’s the only change happening to the 10 other pots. Dependent variable is the height of the plant since that’s what Ramona wants to see change as the output. Control group is the 5 pots without the radio i’m pretty sure. The constants are the amount of seeds, pots, soil, and water.

Can someone help me please!!
Answer:
y = (-3x/5) +1
Step-by-step explanation:
We know that the line passes through the point (-5 , 4)
AND
the slope is given to be -3/5
let's look at the slope a bit more
we know that the formula for slope of a line is Rise / Run
Which means that the rise of this line is -3 after spanning 5 units to the right
Hence, the line goes down 3 units after moving 5 units to the right
We know that to find the equation of a line through the point-slope equation, we need the slope as well as the y-intercept of the line
since we are already given the slope, we need to find the point where the line intersects the y-axis
Now, back to the given point the line passes through
this point has a x - coordinate of -5 and we know that after moving 5 units to the right, the line moves 3 units downwards
So, if the line moves 5 units to the right from the given point, it will reach the y- axis and we know that it's y-coordinate will decrease by 3
Hence, the y-intercept will be 3 units below the given y -coordinate
y - intercept = (4 - 3) = 1 = y-intercept
Now, using the slope-intercept formula to get the equation:
y = (slope)*x + (y-intercept )
y = (-3/5)x + (1)
y = (-3x/5) + 1
F(x) = -2x^2 + 6x-3, opens (down or up) and has a (maximum or minimum) value
Answer: D
Step-by-step explanation:
(Using the formula in my attachment)
x^2 − 6x + 19
(x - 3)^2 = x^2 - 6x + 9
9 - e = 19
e = -10
(x - 3)^2 - e
(x - 3)^2 - - 10
(x - 3)^2 + 10
when x - 3 = 0, x = 3
Subsitute 3 into the equation
(3 - 3)^2 + 10
0 + 10
Minimum (3,10) in this case f(3) = 10

(X+2) 3 = (x-4) 5
distribute on both sides: 3x + 6 = 5x - 20
add 20 to both sides: 3x + 26 = 5x
subtract 3x from both sides: 26 = 2x
divide both sides by two: 13 = x
