Meg wants to take tennis lessons. In the chart, four instructors are listed with what they charge. Which instructor gives the best deal? Mark $100 for 10 hours Rick $80 for 9 hours Steve $75 for 8 hours Andy $60 for 5 hours
Mark charges $10.hour. Rick charges $8.89.hour. Steve charges $9.38/hour. Andy charges $12/hour. The best deal is to take tennis lessons from Rick.
So Rick would be the choice
Answer:
16x + 13
Step-by-step explanation:
(4x + 11) + (12x + 2)
combine like terms (add the x's and add the numbers)
4x + 12x = 16x
11 + 2 = 13
(4x + 11) + (12x + 2) =
16x + 13
Given equation is y=2x+7 and
Let's simplify the 2nd equation before we can start graph so that calculation will be easy
multiply both sides by 2 to cancel out fractions
y=2x+7
which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.
y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.
