A. It is always true
B. -4*6=-24
3*-7=-21
C. Whenever you have a negative being multiplied by a positive the product is always negative
8. D: The <em>longest sides of the quadrilaterals are 30 and 10</em>. That is a 30 : 10 ratio, which simplifies to <em>3 : 1, or </em>3/1. It's not 1 : 3 because it is the ratio between the large (comes first) to the small (comes second) figure.
9. B: <em>x corresponds to 26</em>, and from the previous problem, we figured out that <em>the sides of the larger figure are 3 times larger than the corresponding one on the smaller one</em>. So <em>x is 1/3 the length of 26</em>, which is 26/3.
Answer:
22 pi
Step-by-step explanation:
Use y=mx+b
m = 4
x = 0
y = -1
-1 = (4)(0) + b
