What is the correct factorization of x^2 - 2x - 15?

iragen [17]

Answer:

option b

Step-by-step explanation:

${x}^{2} - 2x - 15$

${x}^{2} - 5x + 3x - 15 = 0$

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

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

x = -3 (Not possible)

x = 5

So, x = 5

Solve for y 8x-7y=23 (fill all of the boxes)

bezimeni [28]

Answer:

i think this is the correct answer

Step-by-step explanation:

Simplifying

8x + -7y = 23

Solving

8x + -7y = 23

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

8x + -7y + 7y = 23 + 7y

Combine like terms: -7y + 7y = 0

8x + 0 = 23 + 7y

8x = 23 + 7y

Divide each side by '8'.

x = 2.875 + 0.875y

Simplifying

x = 2.875 + 0.875y
