Please help me any thing you can do just help me thank you

a. Plan C

b. Plan B

c. Between 8 and 14hrs.

Step-by-step explanation:

a. Plan C = 5hrs = $200 (as plan A = $300 and cost more.)

b. Plan B = 17hrs set rate = £400

c. We see a change at 8hrs for A and then C is more value at 17hrs. So we could say 16hrs if 17hrs is wrong. But 17 Im sure will be correct as we say the word until.

I will do the rest within 12hrs, as something has come up.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
