help me please thanks!

Answer:

D

Step-by-step explanation:

We are dealing with system of equations and can use graphing, elimination, or substitution. However, the equation is set up in a way such that it will be easier to use elimination. You can add the two equations and in doing so you will see the x and -x cancel out. The remaining equation is 2y = 0. So, y = 0. Substitute that into one of the equations and you get that x = 3. Therefore your answer is "D".

A dance troupe is on tour and performing their show in venues of various sizes. The scatter plot shows adult and youth ticket sales data for their last eight performances. A line of best fit has been drawn.

Based on the equation for the line for best fit, about how many youth tickets would the troupe sell for a performance where 150 adult tickets are sold?

A. 82

B. 88

C. 118

D. 243
