Suppose you're given the formula p = 9m – 3n. if you know that n is 1⁄3 of m, how could you rewrite this formula?

a. p = m

b. p = 2(m – n) asap

c. p = 8m

d. p = 3(m – 2n)

Option C -

Step-by-step explanation:

Given : Formula If you know that n is of m.

To find : How could you rewrite this formula?

Solution :  

Step 1 - Write the formula,

Step 2 - Substitute,

Step 3 - Solve,

Therefore, The formula can be re-write as

So, Option C is correct.

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
