Last year, students planted 8 tomato plants and 16 pepper plants in a school garden. This year, the students planted 15 tomato plants. They want to have the
same ratio of tomato plants to pepper plants as last year. Pepper plants cost
$4.33 each. What is the cost, in dollars, of the pepper plants for this year's garden?

what are you trying to solve here

step-by-step explanation:

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
