Y = 4x - 3
y = -x - 13
Since both equations equal y, we will just substitute both equations to equal each other.
4x - 3 = -x - 13
+x on both sides
5x - 3 = -13
+3 on both sides
5x = -10
/5 on both sides
x = -2
Substitute x = -2 into one of the equations.
y = -x - 13
y = -(-2) - 13
y = 2 - 13
y = -11
To check answer, plug in both x and y values into one of the equations.
y = -x -13
-11 = -(-2) - 13
-11 = 2 - 13
-11 = -11
Answer:
x = -2
y = -11

Did the quiz, Trust me.
Answer:52 in each buss
Step-by-step explanation: 472 - 4 (the students in the car)= 468
468 divide by 9(how many busses)
= 52 (students in each buss)
9x + 4=472
9x=468
X= 52
Based on property of triangles, if two of the three sides are exactly doubled, so will the resulting length. Both answers are 18.
