Answer:

The coordinates of the vertex are (-5,-28)

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

f(x)=a(x-h)^{2}+k

where

(h,k) is the vertex of the parabola

In this problem we have

f(x)=(x+5)^{2}-28

a=1. h=-5,k=-28

therefore

Is a vertical parabola open upward

The vertex is a minimum

The vertex is the point (-5,-28)

x= −29/4

Answer:

Step-by-step explanation:

−7(x+2)=−3(x−5)

Step 1: Simplify both sides of the equation.

−7(x+2)=−3(x−5)

(−7)(x)+(−7)(2)=(−3)(x)+(−3)(−5)(Distribute)

−7x+−14=−3x+15

−7x−14=−3x+15

Step 2: Add 3x to both sides.

−7x−14+3x=−3x+15+3x

−4x−14=15

Step 3: Add 14 to both sides.

−4x−14+14=15+14

−4x=29

Step 4: Divide both sides by -4.

−4x −4

x=29/−4

x= −29/4

The slope of a line passing through the points (-2, 3) and (2, 7) is 1. a)True b) False
Paraphin [41]
<h3>Answer: True</h3>

Slope formula

m = (y2 - y1)/(x2 - x1)

m = (7 - 3)/(2 - (-2))

m = (7 - 3)/(2 + 2)

m = 4/4

m = 1
