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.
I think it’s B
Hopefully this helps!!
Slide 14: you have to measure it
Slide 11: No they do not form a proportion because they are not related. You can do 20 push ups per minute, while your friend can do 19.
Slide 15: 4. Actual is 15 5. Actual is 35 6. Model is 4 7. Model is 2.5
Slide 13: 1. Proportional 2. Proportional 3. Not proportional 4. Proportional
Slide 12: m=77 a=10 g=16 w=160
Hope I’m not too late!
