Answer: x=−3 or x=13

Step-by-step explanation:

Step 1: Subtract 39 from both sides.

x2−10x−39=39−39

x2−10x−39=0

Step 2: Factor left side of equation.

(x+3)(x−13)=0

Step 3: Set factors equal to 0.

x+3=0 or x−13=0

x=−3 or x=13

Write an equation in point-slope form for the line through the given point with the given slope.

zlopas [31]

Answer:

y+1 = -1(x+10)

Step-by-step explanation:

The point slope equation of a line is

y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line

y - -1 = -1 (x --10)

y+1 = -1(x+10)

Solve for<br> a. 7a-2b = 5a+b

Stels [109]

<span>So we have a problem with two unknows and one equation. We have to express one over the other like this: 7a - 2b = 5a + b. First we separate one kind on the left side and the other kind on the right side: 7a - 5a = b + 2b. Then: 2a = 3b. Now we divide both sides by 2 and get: a= 3b/2.</span>
