g(x)= 1/7x-1, g^-1(6)
Answer:
[tex]g^{-1}(6)=49[/tex]
Step-by-step explanation:
Inverse function
Given the function:
[tex]\displaystyle g(x) = \frac{1}{7}x-1[/tex]
Find: [tex]g^{-1}(6)[/tex]
Find the inverse function of g.
[tex]\displaystyle y = \frac{1}{7}x-1[/tex]
Add 1:
[tex]\displaystyle y +1= \frac{1}{7}x[/tex]
Multiply by 7:
[tex]7(y +1)= x[/tex]
Swap letters:
[tex]y=7(x+1)[/tex]
Call this the inverse function:
[tex]g^{-1}(x)=7(x+1)[/tex]
Evaluate at x=6
[tex]g^{-1}(6)=7(6+1)=49[/tex]
[tex]\boxed{g^{-1}(6)=49}[/tex]

Step-by-step explanation:
Evaluate and solve for the variable and show your work please.
x – 7 = 4 + 10
12 – c = 8
–4 – 10 = 4y + 3y
–42 + 20 = –2x + 13x
x – 7 = 4 + 10 (x=21)
x−7=4+10
x+−7=4+10
x−7=(4+10)(Combine Like Terms)
x−7=14
x−7=14
Step 2: Add 7 to both sides.
x−7+7=14+7
x=21
---------------------------------------------------
12−c=8 (c=4)
12+−c=8
−c+12=8
Step 2: Subtract 12 from both sides.
−c+12−12=8−12
−c=−4
Step 3: Divide both sides by -1.
−c
−1
=
−4

c=4
----------------------------------
−4−10=4y+3y (y=−2)
−4+−10=4y+3y
(−4+−10)=(4y+3y)(Combine Like Terms)
−14=7y
−14=7y
Step 2: Flip the equation.
7y=−14
Step 3: Divide both sides by 7.

------------------------------------
-42=20=-2=13x (x=−2
Simplifying
-42 + 20 = 2x + 13x
Combine like terms: -42 + 20 = -22
-22 = 2x + 13x
Combine like terms: 2x + 13x = 15x
-22 = 15x
Solving
-22 = 15x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15x' to each side of the equation.
-22 + -15x = 15x + -15x
Combine like terms: 15x + -15x = 0
-22 + -15x = 0
Add '22' to each side of the equation.
-22 + 22 + -15x = 0 + 22
Combine like terms: -22 + 22 = 0
0 + -15x = 0 + 22
-15x = 0 + 22
Combine like terms: 0 + 22 = 22
-15x = 22
Divide each side by '-15'.
x = -1.466666667
Simplifying
x = -1.466666667

PLEASE HELP 15 POINTS The sum of the measures
of seven out of ten angles
in a decagon is 1086°. If the
three remaining angles are
equal in measure, what is the
measure of each angle?
Answer:
118
Step-by-step explanation:
1440-1086= 354
354/3=118
The measure of each angle is 118 degrees
The given parameters are:
Shape: DecagonSeven angles add up to 1086The remaining three angles are congruentThe sum of interior angles of a decagon is 1440.
Let each of the remaining three angles be represented with x.
So, we have:
[tex]1086 + 3x = 1440[/tex]
Collect like terms
[tex]3x = 1440 - 1086[/tex]
[tex]3x = 354[/tex]
Divide both sides by 3
[tex]x = 118[/tex]
Hence, the measure of each angle is 118 degrees

Ferdinand Freight Company charges a flat rate of $200 plus $0.75 per pound to transport freight in
the metro area. This cost is represented by the function below where w is the weight of the freight
in pounds and c(w) is the cost given the weight of the freight
c(w) = 200+ 0.750
Answer:
$1325
Step-by-step explanation:
c(w) = 200 + 0.75w
c(1500) = 200 + 0.75(1500)
c(1500) = 200 + 1125
c(1500) = 1325

y= 3x - 10
y= 30r - 10
Answer: the first equation would start at -10 on a graph, and go up 3 over 1. For the second equation it would still start at -10, but go up 30 over 1. The slope of equation 1 -s 3, the slope of equation 2 is 30. That is how they are different.

Answer:
x = -3
Step-by-step explanation:
Step 1: Write equation
12 = 6 - 5x + 3x
Step 2: Solve for x
Combine like terms: 12 = 6 - 2xSubtract 6 on both sides: 6 = -2xDivide -2 on both sides: -3 = xRewrite: x = -3Step 3: Check
Plug in x to verify it's a solution.
Substitute: 12 = 6 - 5(-3) + 3(-3)Multiply: 12 = 6 + 15 - 9Add: 12 = 21 - 9Subtract: 12 = 121. K + 12 > 20, if k = 15

jaun painted 4 portraits in 20 minutes. at that rate how many would he paint in 3 hours
Answer:
36 portraits
Step-by-step explanation:
4 portraits per 20 minutes. 20 minutes x 9= 3 hours. 9x4 portraits=36 portraits.
Answer:
48 portraits
Step-by-step explanation:
He can do 4 in 20 minutes. So, first figure out how many he can do in an hour. That's another 40 minutes. 40 minutes he does 8 portraits. So, 8 portraits plus 4 portraits is 16. That's one hour of painting. 16 portraits times 3 is 48, which is the amount he would paint in three hours.
