Answer:

Step-by-step explanation:

We are given an equation , so we first need to simplify the equation

lets distribute the x on parenthesis first

2x^2 -x- 15 = x^2 + x.

Now bring all terms to the left so we get

2x^2-x-15-x^2-x=x^2+x-x^2-x

x^2-2x-15=0

Now since all terms are in one side , so we now factor the equation

(x-5)(x+3)=0

Now apply the zero product property to get

x-5=0 or x+3=0

x=5 or x=-3

solution x=-3 or x=5

C

Solve for m
MakcuM [25]

Answer:

m = 29/48

Step-by-step explanation:

Given that

x₂ = (y₂-y₁) +10 →(1

y₂ = y₁-x₁ → (2

y₁= 37

x₁ = 29

Now substitute the value of x₁ and y₁ into equation 2

y₂ = 37-29

y₂ = 8

Now substitute the value of y₂ and y₁ into equation 1

x₂ = (8-37) +10

x₂ = -19

As we know the slope (m) can be calculated as follows

m =(y₂ - y₁)/(x₂ - x₁)

m = (8- 37)/(-19 - 29)

m = (-29)/(-48)

m = 29/48

So our slope is 29/48
