10.50/1.20 c

Step-by-step explanation:

We need to find the number of chores

$13.50-$3.00 = $10.50

$10.50/$1.20 = 8.75

Janie can not do 8.75 chores, so we have to round up to 9.

In equality is 10.50/1.20 c

To graph a solution set, start at 9 and drag towards the right arrow, towards 10. Do not stop.

Hope this helps :)

I'm not the best at inequalities ;-;

a

step-by-step explanation:

a

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
