Mary is saving money for college expenses. She saves the same amount each month. The table shows the amount of money Mary has sa
Phoenix [80]

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=Kx

where

K is the constant of proportionality or slope of the linear equation

In this problem

x ----> is the number of months

y -----> is the total amount savings

we have the ordered pairs

(4,80) and (7,140)

so

Find the value of K

K=y/x

For (4,80)

K=80/4=20

For (7,140)

K=140/7=20

The value of K is the same for both ordered paits

that means------> is a proportional relationship

therefore

the linear equation is

y=20x

the answer is the option A, C and D

Please help with this one
anyanavicka [17]

Ok this inequality tells you the number of devices you can have before the new plan costs more than the old plan. The new plan expression is $4.50x + $94m =  y ( total cost). The old plan is $175m = y (total cost). You can see m (number of months) in both equations, you don't need it this time since we're going to to compare both to one month. Since they're both equal to y you can make them equal to each other. $4.50x + $94 = $175. Now you want to figure when the new plan is less than the old plan you switch the equal sign for a less than sign. $4.50x + $94 < $175; this will help you find the inequality you want. From there just use algebraic steps to find that x has to less than 18 or

x < 18.
