Answer:
y= 5x+10
Step-by-step explanation:
Inverse basically means y is now x and x is now y.
y= x/5 -2 becomes x= y/5 -2
Remember to always leave your equation f(x) = ...
i.e. y =...
x= y/5 -2
add 2 both sides
x+2 = y/5
multiply 5 both sides
5(x+2) = y
Hence,
y= 5x + 10

Answer:
x=1, y=1. (1, 1).
Step-by-step explanation:
-5x+6=3x-2
-5x-3x+6=-2
-8x+6=-2
-8x=-2-6
-8x=-8
8x=8
x=8/8
x=1
y=3(1)-2=3-2=1
Answer:
I need to know the dimensions to solve
Answer:
d
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition y = 
when x = 
, then
= k( )² = 
k ( multiply both sides by 8 )
1 = 2k ( divide both sides by 2 )
k =
y = x² ← equation of proportion
When y = 
, then
= x² ( multiply both sides by 2 )
9 = x² ( take the square root of both sides )
x = ± 
= ± 3
with positive value x = 3 → d
-d would equal 3. just flip its around right?
