Answer:
y = 57
Step-by-step explanation:
y α x
y = kx ; k = Constant of proportionality
81 = k* 54
k = 81/54
k = 1.5
Value of y when x = 38
y = kx
y = 1.5 * 38
y = 57
Hence, y = 57 when x = 38

Answer:

Step-by-step explanation:
f(x) + n - shift the grapf n units up
f(x) - n - shift the grapf n units down
f(x + n) - shift the grapf n units to the left
f(x - n) - shift the grapf n units to the right
-f(x) - reflection about the x-axis
f(-x) - reflection about the y-axis
============================================
Look at the picture.

move the graph 2 units to the right and 1 unit up

move the graph 4 units down

reflection the graph about the X axis.
Answer:
(-11, -12)
Step-by-step explanation:
we need one variable to x out
on the note of x, lets cancel out the xs
6x+3y=-102
3x+y=-45 < same as 6x+2y-90
6x+3y=-102
-
6x+2y=-90
y=-12
substitute y in
3x-12=-45
3x=-33
x=-11
(-11, -12)
