Answer:
Step-by-step explanation:
- 3x-2y =7
- x+2y= -3
- 4x=4
- x=4/4
- x=1
- 3x-2y=7
- 3(1)-2y=7
- 3-2y=7
- -2y=7-3
- -2y=4
- 2y=-4
- y=-4/2
- y= -2
- Verify solution
- x+2y= -3
- 1+2y= -3
- 2y=-3-1
- 2y= -4
- y= -4/2
- y= -2
Answer:
y = -5
Step-by-step explanation:
-3x +9y = -57
Let x = 4
-3*4 +9y = -57
-12 +9y = -57
Add 12 to each side
-12+12 +9y = -57+12
9y = -45
Divide each side by 9
9y/9 = -45/9
y = -5
Answer: The distance is d = 13 .
Step-by-step explanation:
In order to find the distance between the two points, you need the distance formula:
where there is
and
.
-Use the those two points
and
for this formula:

-Then, you start solving:





So, therefore, the result is
.
