Help me with the steps for y = 4x + 2 please.
Aleks04 [339]
You are correct. 4 is the slope and 2 is the y intercept. 

Reasoning:

y = mx + b is the slope intercept form of a line
m stands for slope
b stands for y intercept

In your case, m = 4 and b = 2.

A rectangle is inscribed in a circle of radius r. if the width of the rectangle is x, what is the height of the rectangle?
user100 [1]

The diagonal of length 2r forms the hypotenuse of a right angled triangle with  one leg ( the width of the rectangle) = x. So by Pythagoras:-

(2r)^2 = h^2 + x^2      where h = height of the rectangle

h^2 = 4r^2 - x^2

h =  √ (4r^2 - x^2)     answer

Alik [6]

Answer:

If you're trying to solve for r. r=35

3r=105

3r=105

Step 2: Divide both sides by 3.

3r/3 = 105/3

r=35
