Answer:
6x + 10t
Step-by-step explanation:
We know that each cheese pizza (c) is $6, and each four topping pizza (f) is $10.
Knowing this, the total of all the pizzas is going to be 6* the amount of cheese (c) plus 10* the amount of four-toppings.
6x + 10t
Answer:
18
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use the slope formula:
*Slope is rise over run, hence y (vertical) over x (horizontal)*
Notice that the one in the denominator is positive. This is because the x value for point M is negative one and you're subtracting it from the four. When there are two negative like this, it turns into a positive (+).
Answer:
A. The dilated line lies on the original line.
Step-by-step explanation:
Dilation changes sizes, but not slopes or angles. The dilated line is guaranteed to have the same slope as the original.
The center of dilation is "invariant" (doesn't move) as a result of the dilation. Here, the point (3, 0) is the center of dilation. It is the x-intercept of the original line, so will also be on the dilated line.
The dilated line has the same slope as the original and goes through a point that the original line goes through. Hence it lies on the original line.

How do you do this question?
1. make use of the properties of dilation, as we have done above.
2. plot some points on the original line—(0, 3) and (3, 0) are the intercepts—apply the dilation, and see where the line goes. (You will find (0, 3) ⇒ (-6, 9), and (3, 0) ⇒ (3, 0). Both are on the original line.)
