Answer: True
The domain and range swap when you go from the original function to the inverse. This is because the x and y swap places. Recall that the domain is the set of possible x inputs and the range is the set of possible y outputs.
Zoe to Hannah is 3 to 7.
We want to know x.
24 to x
three goes into 24 eight times so multiply 7 by eight
x=56
Step 1:
The variable is the number of weeks needed to equalize Alexa and her sisters savings.
Step 2:
7x + 60 = 5x + 120
Step 3:
7x+60=5x+120
Subtract 60 from both sides.
7x+(60-60)=5x+(120-60)
7x=5x+60
Subtract 5x from both sides
7x-5x=5x+60-5x
2x=60
Divide both sides by 2.
2x/2 = 60/2
x=30
Step 4:
7(30) + 60 = 5(30)+ 120
210+60=150+120
270 = 270
Step 5:
To find the unknown amount of weeks, you need to rewrite the equation isolate x on the left-hand side of the equation. I just subtracting/simplified the equation until I could solve it.
(tbh got stuck on this one)
Tan = opp/adj
Opp of C = 36
Adj of C = 15
Tan = 36/15 simplified = 12/5
hope this helps :)
I believe it is 4 because 12/3=4
