-2x + (1/2)y = 18

(1/2)y = 2x + 18

y/2 = 2x + 18

y = 2*(2x + 18)

y = 2*2x + 2*18

y = 4x + 36

The x intercept is the value of x, when the y value is 0.

0 = 4x + 36

0 - 4x = 36

-4x = 36

x = 36/-4

x = -9

The x intercept is  -9

I hope this helps.

Answer:

The x-intercept of the line with the equation is -9.              

Step-by-step explanation:

Given : Equation -2x+\frac{1}{2}y=18

To find : What is the x-intercept of the line with the equation ?

Solution :

To find x-intercept we put y=0.

Equation -2x+\frac{1}{2}y=18 substitute y=0,

-2x+\frac{1}{2}(0)=18

-2x=18

x=\frac{18}{-2}

x=-9

Therefore, The x-intercept of the line with the equation is -9.

What’s the volume of the pyramid
ValentinkaMS [17]

Answer:

The volume of the given pyramid is 300 cm³

Step-by-step explanation:

The volume of a pyramid, V_{pyramid}, is given as follows;

V_{pyramid} = \dfrac{1}{3} \times Base \ area \times Height

The height of the pyramid = 12 cm

The side length of the square base of the pyramid = 5 cm

The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²

Therefore, by substitution, we have;

V_{pyramid} = \dfrac{1}{3} \times 25 \ cm^2 \times 12 \ cm = 300 \ cm^3

The volume of the given pyramid, V = 300 cm³.
