So, y-intercept is (0,3) and x-intercept is (3/7,0)

Step-by-step explanation:

We are given:

$y=-7x+3$

We need to find y-intercept and x-intercept

Finding y-intercept

To find y-intercept we put x =0

Solving:

$y=-7x+3\\y=-7(0)+3\\y=3$

So, y-intercept is (0,3)

Finding x-intercept

To find x-intercept we put y =0

Solving:

$y=-7x+3\\0=-7x+3\\-7x=-3\\x=-3/-7\\x=3/7$

So, x-intercept is (3/7,0)

So, y-intercept is (0,3) and x-intercept is (3/7,0)

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800

Alenkinab [10]

For this case we can model the problem as a cylinder.
The volume of a cylinder is given by:
$V = Ab * h
$
Where,
Ab: base area
h: cylinder height
Substituting values in the equation we have:
$800 = Ab * 46
$
From here, we can clear the area of the base
Answer:
An equation that can be used to find the area of the circular base is:
$800 = Ab * 46$
