Mia has a budget of $250 to spend on a health club membership. The monthly membership fee is $20, and there is a one-time regist

Leokris [45]

So we cant go over $250

35+20n=250

now that i put the question in an expression we can take the 35 away from both sides

35+20n=250
-35. -35
_____________
20n=215

now divide 20 by both sides to get (n) alone

20n=215
________

n= 10.75

we round down because we cannot exceed the limit, thus

Determine which of the following graphs is the graph of 8x + 9y - 72.

Fittoniya [83]

Step-by-step explanation:

To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.

Step 1: 8x + 9y - 72 = 0

Step 2: 8x + 9y = 72

Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C

Y-INTERCEPT (vertical line): ( $\frac{c}{b}$ , 0 )

X-INTERCEPT (horizontal line): ( 0 , $\frac{c}{a}$ )

Insert your numbers how it shows in the standard form equation and you should get something like this:

Y-INTERCEPT: ( $\frac{72}{9}$ , 0 )

Simplified Y-INTERCEPT: ( 8 , 0 )

X-INTERCEPT: ( 0 , $\frac{72}{8}$ )

Simplified X-INTERCEPT: ( 0 , 9 )

Insert that into your graph and you should be able to get your answer.
