Because it was reflected across the x axis, the distance between the two points is twice the distance of the old point from the x axis, and the distance from the old point from the x axis equals the distance from the new point to the x axis. The distance from the x axis is the absolute value of the x=y value. 7.5 is the y value, meaning the point is 7.5 units away from y=0, the x axis. The new point is twice this from the old point. 7.5 x 2 = 15. The new point is 15 units away from the old point.
To solve -3y=-5x-12 you would
have to divide everything in the equation by -3
Y=5/3x+4
Answer:
56
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
20(32 + ?) = 1760 ( divide both sides by 20 )
32 + ? = 88 ( subtract 32 from both sides )
? = 56
Answer:
x = -3, y = -7
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
Solve 2x - 1 = 3x + 2 for x.
-x - 1 = 2
-x = 3
x = -3
Evaluate y when x = -3
y = 3 (-3) + 2
y = -7
(-3, -7)
