Two cell phone companies have different rate plans. Runfast has monthly charges $10 plus $4 per gig of data. B A &D’s monthl

melomori [17]

BA&D's plan is better for those who use less data. The intersection point of the two plans is (2, 18), which means that both plans cost $18 when you use 2G of data. Anything using more data than that is less expensive with BA&D's plan.

To find the intersection point,
6+6g=10+4g

We cannot have a variable on both sides, so we will subtract 4g from both sides:
6+6g-4g=10+4g-4g
6+2g=10

Subtract 6 from both sides:
6+2g-6=10-6
2g=4

Divide both sides by 2:
2g/2 = 4/2
g = 2

This is the point where the plans cost the same. If we try a number smaller than 2 in both plans,
6+6(1) = 6+6 = 12
10+4(1) = 10+4 = 14

BA&D's plan is less.

consider the distance equation d=rt, where d is the distance (in feet), r is the rate (in feet per second), and t is the time (i

vesna_86 [32]

Answer:

yes, they are proportional

Step-by-step explanation:

A proportion is a relation that can be modeled by a straight line through the origin. The equation will have the form ...

y = kx

where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.

If you start with the equation relating distance, rate, and time:

d = rt

and you fix the time at 50 seconds, then the equation becomes ...

d = 50t

This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.
