Isolate the variable by dividing each side by factors that don't contain the variable.
Answer = x=-2
Answer:
-11
Step-by-step explanation:
You need to find the difference in y-coordinates and divide that difference into a 7:3 ratio. Then you add that to the y-coordinate of point J.
Difference in y:
-20 - 10 = -30
7 + 3 = 10
7/10 * (-30) = -21
Add -21 to 10:
10 + (-21) = -11
The y-coordinate is -11.
We can use proportions
12/x = 10/5
12*5 = 10x
60 = 10x
x = 6
Check
12/6 = 10/5
2 = 2
It’s so stupid but useful at the same time, it will help you in college
Hope you do well :)
