F(x) = 4 - x² g(x) = 6x
(g - f)(x) = g(x) - f(x)
(g - f)(3) = g(3) - f(3)
g(x) = 6x
g(3) = 6*3 = 18
f(x) = 4 - x²
f(3) = 4 - 3² = 4 - 9 = -5
(g - f)(3) = g(3) - f(3) = 18 - (-5) = 18 + 5 = 23
(g - f)(3) = 23
Answer:
x = 10
Step-by-step explanation:
First, to solve for x, you need to isolate the variable, meaning that it needs to be the only term on one side of the equation. To do this, we'll just cancel out the -3 by adding +3 on both sides of our equation.
x - 3 = 7
+3 +3
x = 10
Leaving us with our answer, x = 10
Hope this helped :)
Answer:
Absolute decrease = 33 million
Relative decrease = 22.45%
Step-by-step explanation:
The number of CD's sold the previous year (2009) was 147 million, and in 2010 it was 114 million. The absolute decrease is 147 million -114 million = 33 million.
The relative decrease is just the percent decrease and it is:
33 million/147 million =22.45% decrease.
Given
Erin Lytle's gross pay is $26,300
She takes a married exemption of $4,000
state income tax rate is 5.5%
Find out she pay in state income tax
To proof
Gross pay = $26,300
married exemption = $4,000
Let the she pay in state income tax = x
5.5 % written in the simpler form
= 
= 0 .055
than the equation becomes
x = 0.055 ( 26300 - 4000)
x = 0.055× 22300
x = $1226.5
Erin Lytle pay in state income tax is $ 1226.5
Hence proved
