Hope this helps
Step-by-step explanation:
Answer:
dy/dx = 9x²+2
dy = (9x²+2) dx
dy/dt = (9x²+2) dx/dt
if x = 2 and dx/dt=5 then
dy/dt = (9*2²+2)*5 = 38*5 = 190
Answer:
Will's share = 48
Olly's share = 32
Step-by-step explanation:
Will's share : Olly's share = 3:2
Will's share = 3x
Olly's share = 2x
3x + 2x = £ 80 {Combine like terms}
5x = 80 {Divide both sides by 5}
x = 80/5
x = 16
Will's share = 3x = 3*16 = 48
Olly's share = 2x = 2*16 = 32
The answer is 4x^2 +5x+9
You will first solve the same variables such as x^2
11x^2 - 7x^2 = 4x^2
now you will solve the variables with x
-3x +8x = 5x
so the answer you will get will be 4x^2 +5x = 9
