First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x
Now you may subtract those two
7-4x= 3x
The formula for converting Fahrenheit to Celsius is:
~Multiply by 1.8 (or 9/5) and add 32.
Hope this helps!!!
As the number of computers that go up, the cost goes up by $500. So when 5 computers are bought it will be $2,500
Steps to finding the inverse:
1. Replace f(x) with y.
2. Swap x and y.
3. Solve the equation for y.
f(x) = 2x - 10
1. y = 2x - 10
2. x = 2y - 10
3. Add 10 to both sides
x + 10 = 2y
Divide both sides by 2
(x + 10)/2 = y
y = (x + 10)/2
f^-1(x) = (x + 10)/2
Answer:
10 minutes
Step-by-step explanation:
Let's call the Acme Company A and Beltone as B
Let m be the number of minutes
A = $21 + $0.05m
B = $15 + $0.11m
- A = B
- $21 + $0.05m = $15 + $0.11m
- $6 + $0.05m = $0.11m
- $6 = $0.06m
- 10 = m
It will take 10 minutes for both prices to be equal.
