Answer:
Step-by-step explanation:
With this being a proportional relationship, the y-intercept MUST be 0.
Thus, the relationship has the form y = C(x) = ($5/movie)x, where x is the number of movies purchased.
To graph this, first plot a dark dot at (0, 0). Then, starting at (0, 0), move your pencil point 1 unit to the right and from this new position 5 units up. Plot a dark dot at (1, 5). Now draw a straight line through (0, 0) to the right through (1, 5).
Opposite angles are equal so the equation is
x + 71 = 108 (A)
Answer:
420
Step-by-step explanation:
For this problem we can use a proportion to solve.
Set up the proportion.
Cross multiply.
Divide.
So, it would cost $13,200 to have a 1,100 square foot roof installed.
