A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!
Answer:
Step-by-step explanation:
A parabolic graph with no real zeros never touches or crosses the x-axis.
If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.
If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.
Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3. (Note: this is strictly an example.) Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,
y = a(x - h)^2 + k. Here h = -2 and k = -1, and so the particular parabola is
y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.
In general form, this would be y = -a(x^2 + 4x + 4) - 1, or
y = -ax^2 - 4ax - 4a -1
and the constant terem (-4a -1) must be an odd negative integer
This is only one of an infinite number of possible equations for the parabola described above.

What is the product of the square of 3 and cube of 5?
The sum of 5.5 and twice a number is -10
What is the number?
n = 7.75
n=2.125
n= -7.75
n=-2.125
Answer:
n=-7.75
Step-by-step explanation:
Based on the given conditions, formulate: 5.5+2×X=-10
Rearrange unknown terms to the left side of the equation:2x=-10-5.5
Calculate the sum or difference:2x=-15.5
Divide both sides of the equation by the coefficient of variable:x=-15.5/2
Multiply both the numerator and denominator with the same integer:-155/20
Cross out the common factor:-31/4
get the result: -7.75
Answer: -7.75

Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.
I need to find an equation, a table, and a graph
Answer:
earnings = $125 + ($50/vacuum)x
Step-by-step explanation:
This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:
The equation represents the man's total earnings. The independent variable is x, the number of vacuums he sells.
Thus, earnings = $125 + ($50/vacuum)x. As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).
Plot a black dot at (0, $125). Now move 2 units to the right from this dot and from there up by $100 to (2, $225). Plot this new point. Then draw a line through the two points you've plotted.
Table:
x earnings
---- --------------
0 $125
1 $125 + $50 = $175
2 $125 + $100 = $225
and so on.
Question 10(Multiple Choice Worth 1 points)
(04.01 LC)
Marneshia walked three over eight of a mile in three over five of an hour. What equation can be used to calculate her unit rate in miles per hour?
a three eighths over three fifths = five eighths mile per hour
b three eighths over three fifths = one and three fifths miles per hour
c three fifths over three eights = one and three fifths miles per hour
d three fifths over three eights = five eighths mile per hour
Answer:
The Answer is A
Step-by-step explanation:
First you take 3/8 and 3/5. After that, you put 3/8 over 3/5. To get Miles per Hour, you want to put distance over time. Next you invert and multiply. When you are doing this you want to have it looking like this: [tex]\frac{3}{8}[/tex] * [tex]\frac{5}{3}[/tex]. Finally you multiply the top and the bottom and reduce the fraction. Your final answer will me 5/8.

Step-by-step explanation:
1. 223 is q added to 158
223 = q + 158
2. d divided by 34 is the same as d
d / 34 = d
3. 299/b = t
4. p = 204 × p
5. 103 is equal to m added to 343
103 = m + 343

Your friend, Susannah, manages a sandwich shop. She collects data on the number of turkey sandwiches sold per day for a week. Explain to her how to find the mean, median, mode, and range of the number of turkey sandwiches sold. How that would be helpful when she orders new turkey sandwich makings? Which measure do you think would be the most helpful for her and why?
Answer:
Step-by-step explanation:
Firstly for the the mean you add all the numbers and divide by how many they are.73+88+85+88+99+134+129 and divide it by 7 .
Secondly for the median arrange the numbers numerical form and pick the middle number.
Mode is finding the most common number.
Range subtract the largest number from the smallest number.the best measure is mean because it shows you all you bought and helps in finding the perfect amount

of the 400 of the sixth graders at school, 60% want more library books. how many students want library books?
Answer:
240
Step-by-step explanation:
it’s simple math!
Since 60% of the 400 kids want more Library books, all you need to do is:
100% - 60% = 40%
find 40% of 400:
400 x 0.4 = 160
then subtract 160 from 400 to get 60%:
400 - 160 = 240
therefore 240 is your answer! :)

At a farmer’s market, two vendors sell fresh milk. One vendor sells 2 liters for $3.80, and another vendor sells 1.5 liters for $2.70. Which is the better deal?
1. 1.5 liters at $2.70 is a better deal because the unit rate is 56 cents.
2. 2 liters for $3.80 because the unit rate is 53 cents.
2 liters for $3.80 because the unit rate is $1.90
3. 1.5 liters at $2.70 is a better deal because the unit rate is $1.80.
Answer: 2 liters for $3.80 because the unit rate is $1.90
Explain how to compare decimals. Use the numbers 6.75 and 6.732 to help you explain this process.
tysm I am struggling
Answer:
6.75>6.732
Step-by-step explanation:
We are given that
6.75 and 6.732
We have to compare two given decimal numbers.
First we convert like decimal number
In 6.75 there are two digits after decimal point.
In 6.732 , there are three digits after decimal point
Therefore, we put zero in 6.75 to convert like decimal number
Now, we get
6.750
Unit place of both decimal numbers are same and tenth place of both decimal number are same.
Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3
5 >3
Therefore, 6.750 is greater than 6.732
6.75>6.732
