The members of a wheelchair basketball league are playing a benefit game to meet their fundraising goal of $900. Tickets cost $15 and snacks cost $6.

The question is incomplete:

The members of a wheelchair basketball league are playing a benefit game to meet their fundraising goal of $900. Tickets cost $15 and snacks cost $6.

a. Write a linear equation that describes the problem

b. Graph the linear equation.

c. If the team sells 50 tickets,  how many snacks does it  need to sell to reach the  goal?

a.15x+6y= 900

b. The graph is attached.

c. 25

Step-by-step explanation:

a. From the information provided, the linear equation has to express that the number of tickets multiply for its price plus the number of snacks multiply for its price would be equal to $900:

15x+6y= 900

x= number of tickets

y= number of snacks

b.

When x= 0:

15(0)+6y= 900

y=900/6= 150

When y=0

15x+6(0)= 900

x=900/15= 60

With these points, you can graph the linear equation and the image is attached.

c. You have to replace the value of x in the equation and isolate y:

15x+6y= 900

15(50)+6y= 900

750+6y=900

6y= 900-750

6y= 150

y= 150/6

y= 25

You need to sell 25 snacks to reach the goal.

step-by-step explanation: where's the phrase?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
