5x - y = -3......this is just a matter of subbing in ur answer choices to see which one makes the equation true.
5x - y = -3.....subbing in (-2,-7)...x = -2 and y = -7
5(-2) - (-7) = -3
-10 + 7 = -3
-3 = -3 (correct)
so ur answer is : B. (-2,-7) <==
Answer:
36 +23i
Step-by-step explanation:
(3+8i) (4-3i)
FOIL
first: 3*4 = 12
outer: 3*-3i = -9i
inner: 8i *4 = 32i
last: 8i * -3i = -24i^2 = -24 (-1) = 24
Add these together
12+-9i+32i +24
Combine like terms
36 +23i
