Answer:

We can easily say the x intercepts are +3 and -7

Or we can multiply (x-3) *  (x+7)

x^2 + 4x -21 = 0

a = 1 b = 4 c = -21

We solve with the quadratic equation

x = 3

x = -7

So that proves our answers are correct.

Write the equation of the line with the given slope and y- intercept. 1.Slope is -2 and a y-intercept of 5.
Monica [59]

Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5


Since the slope is \frac{3}{4}, then m=\frac{3}{4}. Since the y-intercept is -3, b=-3.

Then, we can create the equation: y=\frac{3}{4}x-3

A construction crew is lengthening a road. The road started with a length of 59 miles, and the crew is adding 3 miles to the roa
AlekseyPX

L = total length

D = number of days

they add 3 miles per day which = 3D

equation:  L = 59 +3D

 if they worked for 34 days, replace D with 34 to get:

L = 59 +3(34) =

L=59 + 102

L=161 miles total length after 34 days

AlexFokin [52]

Answer:

-3

Step-by-step explanation:

-2(2x+5)-x=5(x+1) +15

distribute

-4x-10-x=5x+5+15

add common terms

-5x-10=5x+20

move common terms to the same sides

-30=10x

divide

x=-3

Answer:

  ∠K = ∠M = 55°

Step-by-step explanation:

The two marked angles are opposite the sides marked as congruent. That means the angles are congruent, so we have ...

  4x -1 = 2x +27

  2x = 28 . . . . . . . . add 1-2x to both sides

  x = 14

  4x -1 = 4(14) -1 = 55

The measures of the angles are ...

  ∠K = ∠M = 55°
