The most confused that i have been
Trava [24]

Answer:

(-5, -3)

Step-by-step explanation:

To graph the two equations, you can look at two things, the slope and the y-intercept.

The two equations are in slope-intercept form, y= mx + b. m is the slope and b is the y-intercept. The slope is rise/run and the y-intercept is where the line crosses the y-axis.

In the first equation, the slope is -1 and the y-intercept is -8. So, to graph you would start at (0, 8) and move up one unit and then left one unit to get the next point.

For the second equation, the slope is 2/5 and the y-intercept is -1. So, to graph you would do the same thing. Start at (0, -1) and then go up 2 units and right 5 units to get the next point.

I've attached a graph below if you need it.

First, write out the equation as you have it:

x/5=15

Then, multiply both sides of the equation by 5/1:

5/1(x/5)=15(5/1)

Your result is:

x=75

Danny, Pedro, Derick, Jose, and Willy went to a soccer game. They each got a $3-off coupon to buy themselves a ticket to the gam
kondor19780726 [428]
I think it’s 22.4
the total is 37 then divided by 5 for each person. after you divide you add the $3 coupon so for each person would be 3 by 5 to equal 15. so 37 divided by 5 is 7.4 and then add 15 to get 22.4. If this is wrong please correct me :)
