Answer:
7/5
Step-by-step explanation:
3x + 5 + 2x - 12 = 0
5x - 7 = 0
5x = 7
x = 7/5
Multiple-3(x+0.6) and 6(x+2.4) you will get -3x-1.8=6x+14.4 then you add -3x + 6x you will get -9x=14.4+1.8 you add 14.4+1.8 that will give you 16.2 then divide that by -9
First simplify the equation and next multiply the 20 with the x^2 and find a number that adds together to give you the middle
The increase in price was 10%
2.5*.1=.25
2.5+.25=2.75
hope this helps
: Let y = f(x) = x^1/3
Then dy = 1/3*x^(−2/3) dx
Since f(64) = 4.
We take x = 64 and dx = ∆x = 1
This gives dy = 1/3*(64)^(−2/3)* (1) = 1/48
∴65^(1/3) = f(64 + 1) ≈ f(64) + dy = 4 + 1/48 ≈ 4.021 <span>
