What is the slope of this graph
Answer:
-7/8
Step-by-step explanation: If you use RISE/RUN, then you will see that they RISE is 7 and the RUN is 8 so therefroe,you would get 7/8. The graph is pointing down so, it is negative. Overall, your answer should be -7/8.
(5,9), (5-3)
what is the slope?
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you want to find out what the slope is, you have to remember what the formula is first....
[tex]m=\frac{y}{x} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
so in this case -3 would be the [tex]y_{2}[/tex] because it's the y in the ordered pair and it's the second one. Then one of the 5's would be [tex]x_{2}[/tex] and 9 would be [tex]y_{1}[/tex] and then the other 5 would be [tex]x_{1}[/tex].
now if we plug it in
[tex]\frac{-3-9}{5-5} =\frac{-12}{0}[/tex]
now we can tell that we can't divide by zero so the slope would be unidentified and that's it.

3x= 5 + 2(3 + 4x)
How to solve this?
Answer:
Step-by-step explanation:
Simplifying
3x = 5 + 2(3 + 4x)
3x = 5 + (3 * 2 + 4x * 2)
3x = 5 + (6 + 8x)
Combine like terms: 5 + 6 = 11
3x = 11 + 8x
Solving
3x = 11 + 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
3x + -8x = 11 + 8x + -8x
Combine like terms: 3x + -8x = -5x
-5x = 11 + 8x + -8x
Combine like terms: 8x + -8x = 0
-5x = 11 + 0
-5x = 11
Divide each side by '-5'.
x = -2.2
Simplifying
x = -2.2
Answer:
x = -11/5
Step-by-step explanation:
3x = 5 + 2(3 + 4x)
~Distribute left side
3x = 5 + 6 + 8x
~Combine like terms on the left side
3x = 11 + 8x
~Subtract 8x to both sides
-5x = 11
~Divide -5 to both sides
x = -11/5

An airplane flies with a constant speed of 660 miles per hour. How long will it take to travel a distance of 2475 miles?
9514 1404 393
Answer:
3.75 hours
Step-by-step explanation:
Travel time can be found using the relation ...
time = distance/speed
time = (2475 mi)/(660 mi/h) = 3.75 h
It will take 3 3/4 hours to travel that distance.
Reason abstractly. Are all horizontal lines parallel? Use slope
explain how you know.
Answer:
All horizontal lines are NOT parallel.
Step-by-step explanation:
We learned that lines go on forever.
If one line is slightly slanted, and the other line is completely straight, these lines are not parallel, as they will meet at some point.
Hope this helped :)

Find the linear function with the following properties.
f(−4)=6
Slope of f=−6
Given:
f(−4)=6
Slope of f=−6
To find:
The linear function with the given properties.
Solution:
We have,
f(−4)=6
It means, the value of linear function is 6 at x=-4. So, the linear function passes through the point (-4,6).
Slope of f=−6
The point slope form of a linear function is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope of the linear function.
On substituting the values, we get
[tex]y-6=(-6)(x-(-4))[/tex]
[tex]y-6=-6(x+4)[/tex]
[tex]y-6=-6x-24[/tex]
Add 6 on both sides.
[tex]y-6+6=-6x-24+6[/tex]
[tex]y=-6x-18[/tex]
The function form of this linear equation is
[tex]f(x)=-6x-18[/tex]
Therefore, the required function is [tex]f(x)=-6x-18[/tex].

Bob is trying to see if his shadow is longer than Kevin’s. Kevin is 3 feet tall, and Bob is 2½ feet tall. Kevin’s shadow is 5 feet long. Help Bob find the length of his shadow
Given parameters:
Height of Kevin = 3ft
Height of Bob = 2.5ft
Hieght of Kevin's shadow = 5ft
Unknown:
Length of Bob's shadow = ?
We can simply set up simple ratio to solve this problem.
The ratio of Kevin's height to Bob's height is 3 : 2.5
The ratio of their shadow should also be 5: Bob's shadow height
Equating the two of them should give a fairly constant ratio;
[tex]\frac{3}{2.5} = \frac{5}{Bob}[/tex]
3Bob = 5 x 2.5
Bob's shadow height = [tex]\frac{5 x 2.5}{3}[/tex] = 4.2ft
The height of Bob's shadow is 4.2ft.

Paper clips are sold in small boxes and in large boxes.
There is a total of 1115 paper clips in 4 small boxes and 5 large boxes.
There is a total of 530 paper clips in 3 small boxes and 2 large boxes.
Work out the number of paper clips in each small box and in each large box.
Answer:
Small boxes contain 60 paperclips and large boxes contain 175 paperclips.
Step-by-step explanation:
1. Set up two simultaneous equations:
Use s for small boxes and l for large boxes. (You could use any letters)
4s + 5l= 1115
3s + 2l= 530
2. Number the equations:
4s + 5l= 1115 (1)
3s + 2l= 530 (2)
3. Multiply both equations to get the same number of ls (for different questions the letters might be different):
(1) x 2:
8s + 10l= 2230 (3)
(2) x 5:
15s + 10l= 2650 (4)
4. Subtract one from the other to get rid of the ls:
(4) - (3)
8s + 10l= 2230
- 15s + 10l= 2650
7s =420
5. Solve for s:
s= 420/7= 60
6. Substitute the s value into one of the original equations to find l:
4 x 60 + 5l= 1115
240 + 5l= 1115
5l= 1115 - 240
5l= 875
l= 875/5= 175

Maggie's brother is 5 years younger than twice her age. The sum of their ages is 22.
How old is Maggie?
Answer:
9 years old
Step-by-step explanation:
Let maggie's age be m,
and let maggie's brother's age be b
b = 2m - 5,
m + b = 22
Substitute "2m - 5" for b in the second equation (substitution)
m + (2m - 5) = 22 -> Remove parenthesis
m + 2m - 5 = 22 -> Combine like terms
3m = 22 + 5 = 27 -> Divide either side by 3
m = 27/3 = 9
Solution: Maggie is 9 years old
