This one is simple since we already have the two x variables.equal. All we have to do is subtract the equations from one another to get the answer.
So i will subtract the left side by the other left side and the right side by the other right side
-8x - 8y -(-8x + 2y) = 0 -(-20)
distribute negative sign
-8x - 8y + 8x - 2y = 0 + 20
do the math
- 10y = 20
Y = -2
plug t into an equation
-8x -8 (-2) = 0
-8x + 16 = 0
-8x = -16
x = 2
answer (2, -2)
Step-by-step explanation:
Enter the following numbers in the boxes provided sequentially.
First box : 7
Second box: 2
Third box: 3
Fourth box : 4
Fifth box: 8
Sixth box: 3
Answer:
2.7
Step-by-step explanation:
if you round 2.65 to the nearest tenth, it is 2.7
-4 and 2 are the solutions, since that is where they intercept the x axis, and when plugged into the equation, make it true.
