2[x - 4 ]+ 8 = 18

Solve for X

x=9

Step-by-step explanation:

2(x−4)+8=18

(2)(x)+(2)(−4)+8=18(Distribute)

2x+−8+8=18

(2x)+(−8+8)=18(Combine Like Terms)

2x=18

2x=18

Step 2: Divide both sides by 2.

2x÷2=18÷2

x=9

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
