Answer:
Step-by-step explanation:
since they are both equal to 'y', you can eliminate the y but letting the value of y equal to each other
if they are not both equal to 'y', then solve the equation by putting y itself on 1 side
1. sub y=-2x into 2nd equation
-2x = 3x + 25
then solve for x
-5x = 25
x= -5
2.
y-2 =12x
y = 12x +2
(sub this equation into y=x+2)
12x + 2 = x + 2
11x = 4
x = 4/11
hope this makes sense, please let me know if it doesn't and i'll help out some more
i'm not that great at explaining, sorry
Answer:
Step-by-step explanation:
x - 2 (x - 
) = 2 (4 - x) + 10
x − 2 × 
=2(4−x)+10
x−(−x)=2(4−x)+10
x+x=2(4−x)+10
2x=2(4−x)+10
2x=8−2x+10
2x=−2x+18
2x+2x=18
4x=18

Answer:
The slope intercept form is. y = 1/4x - 4
Answer:
6%
Step-by-step explanation:
principal =6000$
time=9years
simple interest=3,240$
now,
Rate=SI ×100/P×T
=3240×100/6000×9
=324000/54000
=6%
