Simplify 6 - 2 3 + (-9 + 5) · 2.

a. -10
b. -12
c. 6
d. -8

-8 thus D.

Step-by-step explanation:

Simplify the following:

6 - 2×3 + (5 - 9) 2

-9 + 5 = -4:

6 - 2×3 + -4×2

-2×3 = -6:

6 + -6 - 4×2

-4×2 = -8:

6 - 6 + -8

6 - 6 - 8 = 6 - (6 + 8):

6 - (6 + 8)

6 + 8 = 14:

6 - 14

6 - 14 = -8:

 -8

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
