Answer:
x=8/9
Step-by-step explanation:
-3.1x+7-7.4x=1.5x+6(x-3/2)
-3.1x-7.4x+7=1.5x+6x-9
-10.5x-1.5x-6x=-9-7
-18x=-16
18x=16
x=16/18
simplify
x=8/9
The correct answer is:
26.5%.
Explanation:
"Percent" means "per hundred", or "out of 100."
Our fraction is out of 200. To change this to something out of 100, we would divide the numerator and denominator by 2:
g(x) = 2x3 + 3x2 - 4x + 2
Find (f – g)(x).
Answer:
-x^3-3x^2+2x+4
Step-by-step explanation:
Just calculate each coefficient of the polynomial separately.
x^3-2x+6-(2x^3+3x^2-4x+2) = (1-2)x^3+(0-3)x^2+(-2-(-4))x+(6-2) = -x^3-3x^2+2x+4.
Answer:
- x³ - 3x² + 2x + 4
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) - g(x)
= x³ - 2x + 6 - (2x³ + 3x² - 4x + 2) ← distribute by - 1
= x³ - 2x + 6 - 2x³ - 3x² + 4x - 2 ← collect like terms
= - x³ - 3x² + 2x + 4 ← in standard form
Answer:
Step-by-step explanation:
To find the inverse of a function, we must replace y for x and then solve for y.
Now we can substitute x=2 into our inverse function
