I believe the answer is -27t - 4
When we add or subtract polynomials, the addition or subtraction is applied to the coefficients of the terms of equal powers.
For the given polynomials, we are required to do subtraction as follows:
(-4.1 x^2 + 0.9 x - 9.8) - (1.7 x^2 - 2.4 x - 1.6)
= -4.1 x^2 + 0.9 x - 9.8 - 1.7 x^2 + 2.4 x + 1.6
= (-4.1-1.7) x^2 + (0.9+2.4) x + (-9.8+1.6)
= -5.8 x^2 + 3.3 x - 8.2
The final expression (solution) is:
-5.8 x^2 + 3.3 x - 8.2
First we need to figure out how much Susan made per hour
117/9 = 13 dollars per hour
Then find out how much she makes in 7 hours
13 • 7 = 91 dollars
$91 in 7 hours
Answer:
18
Step-by-step explanation:
hope this helps! :D
have a miraculous day!! <3
X=-16
X/2+6=-2
Subtract 6 from both sides
X/2=-8
Multiply by 2
X=-16
