Answer:
1st option.
0 to 100 miles per hour
Step-by-step explanation:
as we can see the question states that a particular car' s gas mileage DEPENDS upon its speed.
Since, the independent variable is the domain of the function the speed of the car will act as the domain of the given function.
out of all the option option 1 gives us values of speed( cause its unit is miles/ hour - unit of speed).
so the domain is
0 to 100 miles per hour.
Answer:
15years
Step-by-step explanation:
6000×10×t÷100=9000
600t=9000
t=9000÷600
t=15years
Just 82 because in order for the number to be 83 it would have to be a 5 after the decimal (82.575= 83). Anything lower than a 5 after the decimal (82.375), would be 82. I hope this helps!
Answer:
70/9
Step-by-step explanation:
Let's solve your equation step-by-step.
4−138=6(1−3x)
Step 1: Simplify both sides of the equation.
4−138=6(1−3x)
4+−138=(6)(1)+(6)(−3x)(Distribute)
4+−138=6+−18x
(4+−138)=−18x+6(Combine Like Terms)
−134=−18x+6
−134=−18x+6
Step 2: Flip the equation.
−18x+6=−134
Step 3: Subtract 6 from both sides.
−18x+6−6=−134−6
−18x=−140
Step 4: Divide both sides by -18.
−18x/-18=−140/-18
x=70/9
