Which equation describes the inverse of f(x) = 7x + 8?
Answer:
y = 1/7x - 8/7
Step-by-step explanation:
y = 7x+8
x=7y+8
x-8 = 7y
1/7x-8/7 = y
The inverse of the given function f(x) = 7x + 8 is equal to
g(x) = [x - 8] / 7.
What is a Function?A variable y is said to be a function of the independent variable x if there is a relationship between them such that whenever a numerical value is assigned to x, there is a rule that determines a specific value of y.
As per the given data:
We are given a function f(x) and we have to find its inverse.
For finding the inverse of a function, we need to express x in terms of f(x).
7x + 8 = f(x)
7x = f(x) - 8
x = [f(x) - 8] / 7
Let's assume the inverse of f(x) is g(x).
g(x) = [x - 8] / 7
The inverse of the given function f(x) = 7x + 8 is equal to g(x) = [x - 8] / 7.
Hence, The inverse of the given function f(x) = 7x + 8 is equal to
g(x) = [x - 8] / 7.

Sally's income per month is $1500. She wants to create a budget to be able to afford everything. How much can she spend on "fun" things if she has to pay $500 a month for rent, $50 for phone bill, $100 for groceries, $100 for miscellaneous bills. and $300 for a car payment.
Answer:
450$
Step-by-step explanation:
So lets add otgether everything that she NEEDS to buy, to see how much of 1500$ she can use on what she WANTS to buy.
So:
500+50+100+100+300
=
1050
This is the total cost of what she NEEDS to buy
Now lets subtract this from her income:
1500-1050
=
450
So we now know that the amount of money she has left to spend on what she WANTS is 450$
Hope this helps! :)

Solve for x.
3x < 12
Answer:
X can be anything below 4
Answer:
x should be 1,2, or 3
Step-by-step explanation:
because if you take 3x4 it would be 12 (the same) so that's wrong. so it would have to be lower than that

Step-by-step explanation:
If f(x)=x^2-2x+11, find f (-2)
Answer: f( -2) = 19
Step-by-step explanation:
plug '-2' into every place 'x' is in
so the new equation would be
f(-2) = (-2)^2 - 2(-2) + 11
and now solve :)
f ( -2) = 4 - ( -4) + 11
f (-2) = 4 + 4 + 11
f ( -2 ) = 19
Angie bought 3 1/2 pounds of apples to make a pie. There are 16 ounces in one pound. How many ounces of apples did she buy?
A.16
B.35
C.56
D.74
Answer:
C
Step-by-step explanation:
So, there are 16 ounces in a pound.
There are 3 1.2, or 3.5 pounds.
To find the total ounces, lets multiply the ounces per pound by the total amount of pounds:
16*3.5
=
56
So your answer is 56!
Hope this helps! :)

Answer:
a = [tex]4\sqrt{3}[/tex]
b= 4
Step-by-step explanation:
It's a 30-60-90 triangle based on the given picture. A right triangle too
Use sine, cosine, and tangent to solve for the side.
To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.
OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and [tex]x\sqrt{3}[/tex] for long leg
So either way, b = 4
To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.
OR you can use the same rule, 30-60-90 triangle to save time
a will end up = [tex]4\sqrt{3}[/tex]
8(39 + 11)
a (8 +39) * (8 + 11) = 893
b. (8 x 39) * (8 x 11) = 27456
C. (8 +39) + (8 + 11) = 66
d. (8 x 39) + (8 x 11) = 400

En un estacionamiento cobran $12.00 la hora y $3.00 por 1/4 de hora ¿Cuánto debo pagar si estacione mi coche a las 11.15am y los saque a las 3.00pm
Ayuda plis doy coronita.
Answer:
$45
Step-by-step explanation:
De 11.00am a 3.00pm hay 4 horas de diferencia.
Eso seria 12x4=$48
Pero necesitamos restarle 1/4 de hora, por lo que se estaciono a las 11.15am y no a las 11.00am
1/4 de hora o 15min= $3.00
48-3=45
