First factor the quadratic equation then find the other factor.

To factor the quadratic equation, find two numbers that add to 5 and multiply to -36.

I got 9 and -4.

So, the factors are (x + 9) and (x - 4).

So, C x - 4 is the answer.

I need the following solutions to the following equations.
Alja [10]

Answer:

x = 6

y = -9

x = -25

Step-by-step explanation:

<u>1st Equation</u>

Step 1: Write out equation

3(4x - 3) - 19 = 8x - 4

Step 2: Solve

12x - 9 - 19 = 8x - 4

12x - 28 = 8x - 4

4x - 28 = -4

4x = 24

x = 6

<u>2nd Equation</u>

Step 1: Write out equation

-6y + 14 = 32 - 4y

Step 2: Solve

-2y + 14 = 32

-2y = 18

y = -9

<u>3rd Equation</u>

Step 1: Write out equation

-28 + 5 - 3x = 2 - 2x

Step 2: Solve

-23 - 3x = 2 - 2x

-23 = 2 + x

-25 = x

x = -25

Complete the point-slope equation of the line through (-8, -8) and (-7, 9)
neonofarm [45]

Answer:

Request equation :

y-17x=128

Step-by-step explanation:

As we know that if (x1,y1) & (x2,y2) be two points then it's point slope form equation can be written as

y-y1 = (y2-y1)/(x2-x1) {x-x1}

now we have (-8,-8) and (-7,9) then the equation will become

y-(-8)=(9-(-8))/(-7-(-8)) {x-(-8)}

i.e, y+8=17(x+8)

i.e, y -17x =128
