The table below shows the total number of hours Jessica, Emily, and Trina each studied after a given number of weeks. Weeks Jessica Emily Trina

2 5 5 5

4 10 10 10

8 20 15 20

10 40 20 25

One of the relationships between weeks and total hours studied is proportional.

Whose number of total hours studied is proportional to the number of weeks studied?

For the proportional relationship, write an equation to represent y , the total number of hours studied, in terms of x , the number of weeks.

Explain how you determined your equation.

step-by-step explanation:

it works trust me

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

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
