Answer:
x = 81
Steps:
It says that y ~ √x
We have points (9, 18) as a guide.
We can write y = f(x) = a√x +b
Use points (9, 18) as a guide
18 = a√9 +b
18 = 3a + b
One solution might be a = 6, which means f(x) = 6√x
Thus when y = 54,
54 = 6√x
9 = √x
81 = x

Answer:
y =
x + 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y =
x + c ← is the partial equation
To find c substitute (5, 7) into the partial equation
7 =
+ c ⇒ c = 7 -
= 
y =
x +
← equation of line
-1/3m+1=-7
-1/3m+1-1=-7-1 subtract 1 from both sides
-3(-1/3m)=-3(-8) multiply -3 on both sides
m=24 solution
Simply rearrange the terms and simplify.
Subtracting 4x from both sides, we have:
-11y=-4x-6
Dividing by -11, we have:

This is in the proper form, so this is our final equation.
