Suppose a family starts out 50 miles from home at time t = 0. they travel away from home at a constant speed of 45 miles an hour. what is the equation that tells you how far they'll be from home t hours later?

The required equation tells how far they'll be from home t hours later is  

Step-by-step explanation:

Given : Suppose a family starts out 50 miles from home at time t = 0. They travel away from home at a constant speed of 45 miles an hour.

To find : What is the equation that tells you how far they'll be from home t hours later?

Solution :

Let d is the distance covered in time t at a speed s

The relation between them is

They travel away from home at a constant speed of 45 miles an hour.

The distance covered is

The family starts out 50 miles from home at time t = 0.

So, The total distance they covered is

Therefore, The required equation tells how far they'll be from home t hours later is  

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
