Answer:
(-9, -7)
Step-by-step explanation:
To solve this, i used the elimination method.
17x - 19y = -20
x + y = -16
multiply both sides by -17
and that will give you =
17x - 19y = -20
-17x - 17y =272
then i added the equations.
-36y = 252 (divide both sides by -36)
y = -7
now that you have found the y value, the next step is to find the x value and for that you need to pick an equation and solve it.
x + y = -16
x + (-7) = -16 (replace y with -7)
x = -9
(x,y) = (-9, -7)
Answer:
y intercept:
slope: -1
Step-by-step explanation:
1) We know that y intercepts are when x equals zero! Since we have an equation, we can plug in the value 0 for x to find out the y intercept.
If we do this:
y= 4 x 0 -1
y=-1
This means that the y intercept is: (0,-1)
Y intercepts will be on the y axis. So, graph (0,-1) on your chart.
2) Next, we know that slope is change in y over change in x. So if the slope is -1, we can say that if we move down 1, we move to the right 1.
If we apply the slope to our y intercept you will get a line!
3) If you are still confused, here are some points that belong to this line. If you check, you will see that the slope is -1 ( down 1, to the right 1)!
a) (1, 3) ---> all I did to discover this point is plug in 3 for y in the equation.
b) (2, 7) ---> I plugged in 7 for y
Good luck! Hope this helped.

Answer:

Step-by-step explanation:
If you divide 4/5 you get 80%. Then if you divide 4/9 you get .4444444 which means Nicole's friend only ran 44% of Nicole's distance. That's what i got from there. You might have to multiply more, but that's all I've got from the information you gave me
