Answer: A

Explanation: Line A intersects with the y-axis at +1 and has a slope of 3/1x. This would form the equation y = 3x + 1 in y = mx + b form. Therefore, A matches the equation.

Hope this helps! :)

What is the vertex of (x) = –16x² + 64x + 80.

cricket20 [7]

Answer:

Step-by-step explanation:

f(x) = a(x - h)² + k - the vertex form of the equation of the parabola with vertex (h, k)

$f(x) = -16x^2+ 64x + 80\\\\f(x) = -16(x^2- 4x) + 80\\\\f(x) = -16(\underline {x^2-2\cdot2x\cdot2+2^2}-2^2) + 80\\\\f(x) = -16\big[(x-2)^2-4\big] + 80\\\\f(x) = -16(x-2)^2+64 + 80\\\\\bold{f(x)=-16(x-2)^2+124\quad\implies\quad h=2\,,\quad k=124}$

<u>The vertex is </u><u>(2, 124)</u>

parking garage has 5 floors. If 117 cars can be parked on each floor, how many total cars can park in the garage? Drag numbers t

mr Goodwill [35]

Answer:

585 cars

Step-by-step explanation:

Given

$Floors = 5$

$Cars = 117$ per floor

Required

Determine the total number of cars

This is calculated by multiplying number of cars per floor by number of floors.

$Total = Floors*Cars$

$Total = 5 * 117$

$Total = 585$

<em>Hence, there are 585 cars in total</em>
