Which of the following is a solution to
the equation 0 = x2 – 8x – 13?

x= 32 ± √29

Step-by-step explanation:

x² - 8x - 13 = 0

ax² + bx + c = 0

Comparing equations we get,

a=1

b=(-8)

c=(-13)

Using quadratic formula,

x= b² ± √ b²-4ac

2a

Substituting the values

x= 64 ± √( 64 + 52)

2

= 32 ± √29

Hope this answer helps you

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
