Answer:

Step-by-step explanation:
Let y be the total price and x be the months passed,
Since the enrollment fee is $50, the y-intercept would be 50 regardless of the months passed. Also, since the price increases by $60 every month, we know the gradient is 60.
Therefore, the equation is
Answer:
Step-by-step explanation:
Let the amount donated to City Youth Fund = $x
And the amount donated to the Educational Growth Foundation = $y
Amount donated to the Educational Growth Foundation is at least four times the amount donated to City Youth Fund.
y ≥ 4x ------(1)
Total amount she can donate is up to $440
x + y ≤ 440 ------(2)
And the constraints are x ≥ 0 --------(3)
y ≥ 0 ------(4)
And solution set will be the common shaded area of both inequalities as shown in the graph attached.
(By using a graphing tool we can find the graph).
Answer:
13
Step-by-step explanation:
The coeficcent of a term xa where a is the variable is x. Thus 13a results in 13 as the coeficcent
The correct answer is C because the problem showed ( x + 20 ) and ( x + 8 ) two times in the problem. That explains why there is a two outside of the parentheses.
