Answer:

y = +3/2x + 12

Step-by-step explanation:

get slope

get midpoint

get b

(-7,8) and (-1,4)

get slope

(y₂ - y₁) / (x₂ - x₁)

slope is -2/3

perpendicular slope is the negative reciprocal :

+3/2

y=mx + b

y=+3/2x + b

get midpoint :

(x₁ + x₂)/2, (y₁ + y₂)/2

(-4,6)

get b

y=mx + b

6=+3/2(-4) + b

6= -6+ b

b = 12

y = +3/2x + 12

<h3>What are quadratic equations?</h3>

Given the equation for height as a function of time is h(t) = -16t2 + 1,296

The height of the brick on the ground is h(t) = 0. Substitute h(t) = 0 into the equation as shown:

-16t2 + 1,296 = 0

Subtract 1296 from both sides

-16t² + 1,296 - 1296 = 0 - 1296

16t² = 1296

t² = 1296/16

t² = 81

t = 9secs

Hence the brick will fall to the ground after 9 secs.

Given the function f(x) = -3x2 + 4x + 6, find f(2) and f(3). Choose the statement that is true concerning these two values.

denis23 [38]

Answer:

The value of f(2) is larger than the value of f(3).

Step-by-step explanation:

$f(x) = -3x^{2} +4x+6\\f(2) = -3*2^{2} +4*2+6=2\\f(3) = -3*3^{2} +4*3+6=-9\\$
