What are the intercepts of the equation 7x-2y-14z=56?

The intercepts are

(8,0,0),(0,-28,0),(0,0,-4)

Step-by-step explanation:

we have

step 1

Find the x-intercept

The x-intercept is the value of x when the value of y and z are equal to zero

so

For y=0, z=0

substitute

solve for x

The x-intercept is (8,0,0)

step 2

Find the y-intercept

The y-intercept is the value of y when the value of x and z are equal to zero

so

For x=0, z=0

substitute

solve for y

The y-intercept is (0,-28,0)

step 3

Find the z-intercept

The z-intercept is the value of z when the value of x and y are equal to zero

so

For x=0, y=0

substitute

solve for z

The y-intercept is (0,0,-4)

therefore

The intercepts are

(8,0,0),(0,-28,0),(0,0,-4)

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
