Answer:

$x = 10$

Step-by-step explanation:

To find x-intercept/zero, substitute y = 0.

$2x + 4 \times 0 = 20$

Any expression multiplied by 0 equals 0.

$2x + 0 = 20$

When adding or subtracting 0, the quantify does not change.

$2x = 20$

Divide both side of the equation by 2:

$x = 10$

Answer:

Step-by-step explanation:

x- intercept is where the equation intersect the x-axis. So, at x-axis y = 0

2x + 4*0 = 20

2x = 20

Divide both sides by 2

2x /2 = 20/2

x = 10

Graph linear system and estimate the solution y=5x + 2 y=3x

NeTakaya

Y = 5x + 2
y = 3x

5x + 2 = 3x
- 5x - 5x
      2 = -2x
   -2 - 2
       -1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)

Create a six sided cube that shows examples of different solids and explain how to calculate the surface area and volume of each

gulaghasi [49]

We are given a six-sided cube. To determine the surface area and the volume of the cube, we need to know the area of one side:

All sides of the cube are squares with side, s. The area of one square is

A = s^2

The surface area of a cube is the sum of all areas of the sides. So

SA = 6 sides * s^2
SA = 6s^2

The volume of the cube is

V = s^3

The volume of the cube represents the total solid area of the cube which includes the space inside the solid.

What is the Median for the following set of numbers? â€‹21 23 76 47 55 135 45 30 17

Leno4ka [110]

Answer:

Median = 45

Step-by-step explanation:

We are given the following data set:

21, 23, 76, 47, 55, 135, 45, 30, 17

Median is the number that divides the data into two equal parts.

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$
