Elmo has two different part tike jobs and he works 20 hours per week at each job. He earns $8 per hour at one job. Which expression represents how much Elmo earned last week if he earns d dollars per hour at his other job?

Earned = 160 + 20d

Step-by-step explanation:

Seeing as Elmo works 20 hours per week at each job, that means he worked 20 hours at the $8 job and 20 hours at the $d job.

First find how much he earned from his $8/hr job.

(20)8 = 160

Elmo earned $160 at this $8/hr job.

Next, we know he earns $d/hr at his other job, and he works 20 hours at that job as well.

(20)d = 20d

Add the earnings from both jobs together.

160 + 20d = total earnings

step-by-step explanation:

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
