Answer:
x=0
y=6
Step-by-step explanation:
3y- 12x = 18
2y-8x= 12
rearrange the equation
2y-8x=12
add 8x to both sides
2y=8x+12
divide both sides by 2
y=4x+6
now substitute it into 3y-12x=18
3(4x+6)-12x=18
simplify
12x+18-12x=18
simplify
18=18
x=0
substitute to find y
2y-8(0)=12
2y=12
y=6
Recheck:
3(6)-12(0)=18
18=18
2(6)-8(0)=12
12=12
Answer:
-38/4, -2 38/4, -4 38/4, -6 38/4
Step-by-step explanation:
x+(x+2)+(x+4)+(x+6) = -26
4x+12=-26
4x= -38
x=-38/4
Equation of a line: y=mx+b
m=slope(-1)
b=y-intercept(-7)
y=-1x-7 or y=-x-7
Answer:
The correct to the question about is simply C. A is ruled out because it doesn't represent refections
Answer:
3
Step-by-step explanation:
Points A and B lie on the horizontal line y = 1. The length of segment AB is then the difference of the x-coordinates of the points:
5 -2 = 3
The length of side AB is 3 units.
