If 21 is the final answer to the equation then x would be 9
x (3-5) + (4b)
= x ( -2) + (4b), since x=8 b=3
= -16 + 12
= -4
What I did there is substitution
Replacing x with 8 ,and b with 3
So -16 is the product of (-2) and 8
And 12 is the product of 4 and 3
FYI: -2 is the result of 3 - 5
Answer:
3m² + 7m - 6
Step-by-step explanation:
2m (3/2m + 1) + 3(5/3m - 2)
(3m² + 2m) + (5m - 6)
3m² + 2m + 5m - 6
3m² + 7m - 6

Answer:
Step-by-step explanation:
<u>Proportional relationship is:</u>
- y = kx, where k is the constant of proportionality
We have a point (5, 2). it means x = 5, y = 2
<u>Substitute x and y and find k:</u>
