Answer:
A. Yes. Each x value has only one y value. No x value has 2 different y values.
B. For the table, y is 8 when x is 11.
Plug in the value to determine the y value for the equation.
f(x)= 5(11)-21
f(x)= 55-21
f(x)= 34
Since 34>8, the value of the equation f(x) is greater when x=11.
C. 99=5x-21
120=5x
x=24
Final answer: 24
Step-by-step explanation:
<u>The answer is A. Multiply both sides of the top equation by 2</u>
So since we know that 4 × 2 = 8, it would only make sense to multiply both sides by 2 so that the top equation has the x coefficient be 8.
The answer is: "4" .

<u>Note</u>: The question asks for a whole number.
"The area of the triangle above will equal one half of a rectangle that is 5 units long and <u> 4 </u><u /> units wide. (Input only whole numbers, such as 8.).
______________________________________________________
<u>Note</u>: The diagram shows a "right triangle" ; which would be "one-half" of a rectangle, with units of "length" being "5 units" (as mentioned in this very question prompt; and a width of "4" units (as shown in the diagram; hence the answer is "4" units).
Furthermore, the formula/equation for the area, "A" , of a triangle is:
A = (1/2) * b * h ;
that is:
Area = (1/2) * (base length) * (perpendicular height).

As such, the answer, "4" (units) makes sense.

F. 30 is the correct answer, for mean you just have to add all the ages together and divide by the number of customers
Answer:
-40
Step-by-step explanation:
f(5)= -(5)^2-3(5)
-25-15=-40
