Step-by-step explanation:
B/-7 = 4
Cross multiple
-7×4 = B
-28 = B
150 x .30 = 45
You saved $45 if you use the coupon for the skateboard
(a) False. The number 7 is NOT an element of set B as 7 is not in the set B (2, 3, 4 and 0 are though)
(b) False. 3 is a member of set A. It is the third element listed in the set. So saying "3 is not a member of set A" is a false claim
(c) True. The value 0 is found in set B. It is the last element listed.
Final Answer: Choice C)
(4,5),(-3,-1)
slope = (-1 - 5) / (-3 - 4) = -6/-7 = 6/7
y - y1 = m(x - x1)
slope(m) = 6/7
using points (-3,-1)...x1 = -3 and y1 = -1
now we sub...pay attention to ur signs
y - (-1) = 6/7(x - (-3) =
y + 1 = 6/7(x + 3) <===
