Let
x--------> the amount you have left to spend
y--------> the cost of a shirt you want
z------> the amount of the gift card
we know that
--------> equation 
--------> equation

therefore
<u>the answer is the option</u>
x+15 is less than or equal to 60
Answer:
x = 2
Step-by-step explanation:
For quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a).
Here, we have a=2, b=-8, so the axis of symmetry is ...
x = -b/(2a) = -(-8)/(2(2)) = 8/4
x = 2
Answer:
Plug in and determine solution
Step-by-step explanation:#9-11 plug in the degrees C on the left side of the table into the equation and that should give you the degrees F, something like with #9; F = 9/5 (0) + 32.
#12-13, they have a relationship because Celsius can be converted to Farenheit and vise versa
The inverse of a function is determined by substituting f(x) by y and expressing the function in terms of x = ... Then exchange the places of x and y. In this problem, y = 0.5 x -1; x = 2(y+1) . Then g(x) = y = 2x +2. The graphs are linear but g(x) has a larger slope compared to f(x).
