Y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value and 'm' is the slope.

y - 8 = -1.2(x - 7)

Distribute -1.2 into the parenthesis:

y - 8 = -1.2x + 8.4

Add 8 to both sides:

y = -1.2x + 16.4

Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).
spin [16.1K]
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7

A membership at a yoga studio costs $35 per month. Write an equation for the cost of the membership, c, that you pay if you keep
Usimov [2.4K]
Since there is no base down payment or anything the equation i think would just be 35m = c
If there was say a one time payment of $20 and then the monthly payments it would look like 20+35m=C
I hope this helps :)

Write an equation that you can use to solve for x.<br><br> Enter your answer in the box.
patriot [66]
X + 60 = 100 (because they are vertical angles, which means that because they are directly opposite of each other, they are of the same measurements).

Solve for x. Isolate the x, subtract 60 from both sides

x + 60 = 100

x + 60 (-60) = 100 (-60)

x = 100 (-60)

x = 40

40° should be your answer

hope this helps
