Aphone company offers two monthly plans. plan a costs $18 plus an additional $0.10 for each minute of calls. plan b costs $22 plus an additional $0.08 for each minute of calls.

answer:

you werent clear with question but here.

step-by-step explanation:

first, you need to write to expressions to model each situation:

plan a: 10+0.15x

plan b: 30+0.1x

next, set the expressions equal to each other and solve for x:

10+0.15x=30+0.1x

*subtract 0.1x from both sides to isolate the variable*

10+0.05x=30

*subtract 10 from both sides*

0.05x=20

*divide both sides by 0.05*

x=400

the plans would have the same cost after 400 minutes of calls.

to find how much money the plans cost at 400 minutes, plug 400 into either expression.   we'll use plan a:

10+0.15(400)

10+60

70

the plans will cost $70.

hope this !

where are the options?

step-by-step explanation:

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
