Let x represent the first number, y represent the second, and z represent the third.
x + y + z = 92
z = 3x
x = y - 7
Solve x = y - 7 for y.
x = y - 7
x + 7 = y
Fill in y and z so that we only have to worry about x for now.
x + y + z = 92
x + (x + 7) + (3x) = 92
x + x + 7 + 3x = 92
5x + 7 = 92
5x = 92 - 7
5x = 85
x = 85/5
x = 17
Solve for y.
y = x + 7
y = (17) + 7
y = 24
Solve for z.
z = 3x
z = 3(17)
z = 51
So x = 17, y = 24, and z = 51.
If we look at where it is now, we would have multiplied the x and y values by 1/2. since we are working backwards, lets multiply by 2 instead...giving us the vertex for the pre-image....
J is now (0, -2) multiply by 2
J was (0, -4)
Answer:
x=21
Step-by-step explanation:
Notice the right angle. Perpendicular to it on the right, we have two complementary angles, 25, and 3x+2 (you can ignore the parentheses basically). Because they are complementary angles, they will add up to 90, so we can make an equation to solve for x:
25+3x+2=90
3x+2=65
3x=63
x=21
So x=21 is the correct answer. Let me know if you have any questions about my explanation.

Answer:
A) -7/9
Step-by-step explanation:
-4(x + 4x) = 2(2 - x) + 10
-4x - 16x = 4 - 2x + 10
-4x - 16x + 2x - 4 - 14 = 0
-18x -14 = 0
-18x = 14
x = - 14/18
x = - 7/9
