ANSWER:
STEP-BY-STEP EXPLANATION:
We have the following equation:
The inverse is the following (we calculate it by replacing f(x) by x and x by f(x)):
The domain would be the range of the original equation, and it would be the range of values that f(x) could take, which was from -4 to positive infinity, that is, f(x) ≥ -4.
Therefore, the domain is x ≥ -4.
So the correct answer is D.
1/3 of an hour is 20 minutes. If show 10 laps in 5 minutes, just divide 20 by 5, which gives you 4, then multiply 4 times 10. She can swim 40 laps in 1/3 of an hour. Hope that helps. Mark Brainliest if it does. Thank you!
I think that x would be 1.5.
6 = 4x, 6/4 = 1.5, so 1/5 = x
The answer is that it's a right triangle. One angle is 90°
First, you would find out how much 1 gallon of gas would cost
You would calculate $19.46 divided by 14 gallons
Your quotient is $1.39
Then, you would divide how much money you actually have ( $8.70 ) by how much 1 gallon is ( $1.39 )
You get 6.25...
But since you cannot by 1/4 a gallon, you would round your quotient down to 6
Solution : 6 gallons
Mark brainliest if this helped :D
