C=3.14 x 26
C=81.64
C=2(3.14 x 13)
C=81.64
Answer:
Assuming they bought the same shoes, $82.5
Step-by-step explanation:
80% of Original Shoe price = $82
Divide by 0.8 to find the original price.
82 / 0.8 = 102.5
102.5-20=82.5
Answer: 30y + 15x
If x is for sneakers, and y is for high heels, plug 15 in for a and 30 in for b. This means that x is how many sneakers she buys, and y is how many high heels she buys. The equation altogether represents the total amount of her purchases.
Answer:
(4, 3)
Step-by-step explanation:
If this point is reflected about the x-axis, the x-coordinate does not change. The original y-coordiate, -3, becomes +3.
A': (4, 3)
In order for a function to be odd, we know that f(-x) = -f(x)
Hence, the only graphs that are odd are the cubics.
Now, a monomial is defined as an equation with only one term in it. Since the first two is shifted, they must consist of at least 2 terms.
Hence, the only viable answer is the third graph.
