Answer:
(1/2(2x+14)-7) = 1x+7-7= x g(f(x))= 2(1/2x-7)+14= x-14+14= xWe have the result being two variables of linearity hence they are not inverses. In order to be inverses they should have had switched notations, ie: -x vs x9514 1404 393
Answer:
A: (f∘g)(x) = x
B: (g∘f)(x) = x
C: the functions are inverses
Step-by-step explanation:
A: (f∘g)(x) = f(g(x)) = f(2x +14)
= 1/2(2x +14) -7 = x +7 -7 = x
(f∘g)(x) = x
__
B: (g∘f)(x) = g(f(x)) = g(1/2x -7)
= 2(1/2x -7) +14 = x -14 +14 = x
(g∘f)(x) = x
__
C: When a function is operated on by its inverse, then original argument value is restored. That is the case for functions f and g, so the two functions are inverses.

One year, the population of a city was 132,000. Several years later it was 149,160.
Find the percent increase.
Answer: 13%
Step-by-step explanation:
To find the percent increase, first find the increase in figures:
= 149,160 - 132,000
= 17,160 people
Then find the percent increase in this manner:
= Increase / Previous population * 100%
= 17,160 / 132,000 * 100%
= 13%

Help please!!! Find the measure of A in the picture below.
Answer:
Step-by-step explanation:
If you draw in BD, you can show that triangle BCD = triangle BAD by SSS
That means that <A = <C parts of congruent parts are congruent.
<A + <C + 115 + 71 = 360
<A + <C + 186 = 360 All convex quadrilaterals have 4 interior angles that add to 360 degrees
<A + <C = 360 - 186
<A + <C = 174
So call <A and < C = x
x + x = 174
2x = 174
x = 174 / 2
x = 87
<A = 87

Which choice is equivalent to the quotient below?
40/8
Answer:
A.
Step-by-step explanation:
You simplify the square root until you narrow it down to the square root of 5.
The quotient of expression of √40/√8 is √5 which is correct option (A).
What is expression?Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
Given expression as :
⇒ √40/√8
Factor of √40 = √8×√5
⇒ (√8√5)/√8
Cancel out of√8
⇒ √5
Hence, the quotient of expression of √40/√8 is √5.
