Answer:
50%
Step-by-step explanation:
(V2−V1)|V1|×100
=(7.5−5)|5|×100
=2.55×100
=0.5×100
=50%change
=50%increase
Answer:
1. -4/7
2. 4/3
3. x^2 + 16x + 63
4. x^2 + 19x + 90
Step-by-step explanation:
1. (1, 8) and (8, 4)
slope = m = (8 - 4)/(1 - 8) = -4/7
2. (2, 4) and (5, 8)
slope = m = (8 - 4)/(5 - 2) = 4/3
3. (x + 9)(x + 7) =
= x^2 + 7x + 9x + 63
= x^2 + 16x + 63
4. (x + 10)(x + 9) =
= x^2 + 9x + 10x + 90
= x^2 + 19x + 90
Answer
Step-by-step explanation:
I believe the answer is 5 because if however many times you can multiply 2.5 into 12.5, you get the answer of 5.
