Answer:
1. y = 30x
2. y = x+5
3. y = 2x
4. y = x+2
Step-by-step explanation:
1. The speed of a car is x miles per hour. The total distance the car covers is 30 minutes is y
Total Distance = y
Time = 30 minutes
Speed = x
So, equation will be y =30x
2. Tina's age y is 5 years more than her brother Tim's age x.
Tim's age = x
Tina's age y= x+5
So, y = x+5
3. The cost to produce a table y is two times the cost to produce a chair,x
Cost of chair = x
Cost of table = y = 2x
So, y = 2x
4. The time required to bake a chocolate muffin, y is 2 minutes more than the time required to bake a vanilla muffin x
Time to bake vanilla muffin = x
Time to bake chocolate muffin= y= x+2
so, y = x+2
Hello,
f^(-1)(f(x))=f^(-1)(1/2 * x)=2*(1/2 * x)=(2*1/2)*x=1*x=x
f(f^(-1)(x))=f(2x)=1/2* (2x)=(1/2*2)*x=1*x=x
In this case, all you have to do is divide 0.9 miles by 6, in which you get 0.15 miles. Multiply this by 5280 to get the answer in feet, which is 792 feet.
