A set of weights includes a 4lb and 6 pairs of weight plates. Each of plates weights 20lb. If x pairs of plates are added to the barbell , the total weight of the barbell and plates in pounds can be represented by f(x) =20x +4. What is the range of the function for this solution ?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

r and t.

both are 64 degrees.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
