Answer:
f⁻¹(x) = -(x+4) / 5
Step-by-step explanation:
Given function is :
f(x) = -5x-4
We have to find the inverse of given function.
Step 1. Put y = f(x) in given function
y = -5x-4
Step 2. Add 4 to both sides of above equation
y+4= -5x-4+4
y+4 = -5x
Step 3.Divide by -5 to both sides of above equation
y+4 / (-5) = -5x / (-5)
-(y+4) / 5 = x
Step 4 . Swap sides
x = -(y+4) / 5
Step 5. Put x = f⁻¹(y) in above equation
f⁻¹(y) = -(y+4) / 5
Step 6. replace y with x
f⁻¹(x) = -(x+4) / 5 which is the inverse of f(x) = -5x-4.
Second answer: f - 52 = 63.
Okay, so you didn't really put anything for me to know what you wanted to solve, so I'm going to assume this is Scientific Notation:
We have:
10^5 = 100,000 x 4.84 would be: 484,000
10^2 = 100 x 3.9 would be: 390
10^7 = 10,000,000 x 8.91 would be: 89,100,000
The answer is that 4 dog toys are squeaky.
We are going to multiply 12 by 1/3 to find what one third of 12 is.
12*1/3
So when you multiply the numerators and denominators, you get 12/3 which can be simplified to 4.
Answer:
-3/5x + y = - 26/5
Step-by-step explanation:
First, I put everything in slope-intercept form, just because it's more simple for me.
y = 3/5x + b
Since we don't have b, we can use the coordinate they give us to solve for it.
-4 = 3/5 (2) + b
-26/5 = b
y = 3/5x - 26/5
Now, we can move the variables around to fit the form:
Ax + By = C
-3/5x + y = - 26/5
I hope this helped!
