He front of an a-frame house is in the shape of a triangle. the height of the house is 20 feet. the area of the a-frame is 600 square feet. write and solve an equation to find the base of the a-frame house.

Equation:

Base: 60 feet.

Step-by-step explanation:

The formula for calculate the area of a triangle is:

Where:

A: is the area of the triangle.

b: is the base of the triangle.

h: is the heigth of the triangle.

Knowing the area of the triangle and its height, you can write the equation:

Where b is the base in feet of the A-frame house.

To solve it:

Multiply both sides of the equation by 2.

Divide both sides of the equation by 20.

Then:

The base of the A-frame house is 60 feet.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
