Answer:
The first one:
−8x4−14x2−3
Step-by-step explanation:
(-4•2-1)(2•2+3)
-4•2 = -8
-8 - 1 = -9
(-9)(2•2+3)
2•2 = 4
4+3 = 7
(-9)(7) = -63
Now we find the one that equals -63:
-8•4-14•2-3
(-8•4)-14•2-3
-32-14•2-3
-32-(14•2)-3
-32-28-3
(-32-28)-3
-60-3
-60-3 = -63
BAM! THE ANSWER!
Answer:
D) 11.
Step-by-step explanation:
y = 5x + p and the point (-2, 1) is on the line, so substituting for (-2, 1):
1 = 5(-2) + p
p = 1 - 5(-2)
p = 1 + 10
p = 11.
Answer:
2x + 4y = 12 and y = -1/2x + 3
