Step-by-step explanation:
Find the inverse of function f. f(x)=9x+7
A. F-1(x)= -9x-7
B.F-1(x)= 1/9x-7/9
C.F-1(x)= 7x+9
D.F-1(x)= 7/9x-1/9
Answer:
B
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9x + 7 ( subtract 7 from both sides )
y - 7 = 9x ( divide all terms by 9 )
[tex]\frac{1}{9}[/tex] y - [tex]\frac{7}{9}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus
[tex]f^{-1}[/tex] (x) = [tex]\frac{1}{9}[/tex] x - [tex]\frac{7}{9}[/tex] → B

Answer:
formula to solve
Step-by-step explanation:
Regular Weekly Pay = Hourly Wage x Hours Worked
Overtime Weekly Pay = Hourly Wage x 1.5 x Overtime Hours
Overtime Hours = The amount of hours worked above-and-beyond 40
hours. If you worked 55 hours in a week, your overtime hours would
be 15.
Total Weekly Pay = Regular Weekly Pay + Overtime Weekly Pay
Total Salary = Weekly Pay x Work Weeks per Year
Example: If you earn $8.35 per hour, work 50 weeks a year, and
average 50 hours/week:
Regular Weekly Pay = 8.35 x 40 = $334
Overtime Weekly Pay = 8.35 x 1.5 x 10 = $125.25
Total Weekly Pay = $334 + $125.25 = $459.25
Total Salary = $459.25 x 50 = $22,962.50
An eagle takes off from the top of a cliff that is 125 meters high and flies upward. After t seconds, the height at which the eagle is flying is given by the equation h(t) = 125 + 1.25t2 where t is in seconds. Find the instantaneous velocity of the eagle at t = 3 seconds. Round your answer to one decimal place.
Answer:
The instantaneous velocity of the eagle at the given time is 7.5 m/s.
Step-by-step explanation:
Given;
height of the cliff, h = 125 m
the height at which the eagle is flying, h(t) = 125 + 1.25t²
The velocity of the eagle is given by;
v = dh/dt
v = 2.5t
The instantaneous velocity of the eagle at t = 3 seconds is given by;
v = 2.5(3)
v = 7.5 m/s
Theerefore, the instantaneous velocity of the eagle at t = 3 seconds is 7.5 m/s.

A share of stocks gained 12 points, then lost 114 points, and then gained 218 points. Find the overall change in its value.
Answer:
The overall change is 116points gained
Step-by-step explanation:
Points gained = 12points
Points lost = 114points
Points gained = 218points
Unknown:
Overall change in its value = ?
Solution:
The overall change = Total points gained - Total points lost
= (218 + 12) - 114
= 116points
The overall change is 116points gained
Answer:
its 116
Step-by-step explanation:
12 - 114
-102 + 218 = 116

Answer:
The answer is option DStep-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Z
To find the value of ∠Z we use tan
We have
[tex] \tan(∠Z) = \frac{28}{25} \\ ∠Z = { \tan }^{ - 1} \frac{28}{25} \\ ∠Z = 48.239700...[/tex]

1. Mr. Samuels' bank account was in the red, at – $50. For two weeks, he worked at a few odd jobs and made $12, then $24, then $14. What will Mr. Samuels' bank account statement say after he deposits the money, he earned from working these odd jobs? Draw a number line and model the process that leads you to your ans
Answer:
0
please check the attached image for a number line
Step-by-step explanation:
Because Mr Samuels account is in the red, his account would be in the negative. Cash additions to the account would be an addition to the account. This would reduce the negative amounts in the account
-$50 + $12 + $24 + $14 = 0

Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.17x + $15.89
Complete question :
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.17x + $15.89. How much did Hans pay for his trip?
Answer:
$92.39
Step-by-step explanation:
Given that:
Total distance = 450 miles
Amount charged for fees and taxes = $15.89
Amount charged ti redeem each mile = $0.17
In the equation:
Y = $0.17x + $15.89
X = distance Hans is flying
Y = cost of trip
Y = $0.17(450) + $15.89
Y = $76.50 + $15.89
Y = $92.39
AABC is isosceles.
AB = 3x - 4 and BC = 5x - 10.
AB = [?]
If AB = BC then set up the equation 3x - 4 = 5x - 10
Subtract 3x.
-4 = 2x - 10
Add 10.
6 = 2x
Divide by 2.
3 = x
AB is 3x - 4 so
3(3) - 4
9 - 4
5.
AB = 5
If AB is not equal to BC then this is not solvable.
But if they are I am sure AB = 5.
Hope this helps

−1 as a standard form.
A negative exponent means to move the decimal point to the left the number of the exponent.
10^-1 you would move the decimal 1 place to the left.
5.401 x 10^-1 = 0.5401
[tex]\huge\boxed{0.5401}[/tex]
We have the equation...
[tex]\boxed{5401*10^-^1=(?)}[/tex]
Multiply 5401 by 10⁻¹.
[tex]\boxed{5401*10^-^1=0.5401}[/tex]
Therefore, your final answer is [tex]\boxed{0.5401}[/tex]
