It’s the last answer because the slope equals 1 which basically equals just x. And the y intercept is -5

Graph solve for y 5y-x=20

Tomtit [17]

$5y-x=20$ <em>add x to both sides</em>

$5y=x+20$ <em>divide both sides by 5</em>

$\boxed{y=\dfrac{1}{5}x+4}$

It's the equation of a line. We need only two points to the plot the graph.

Choice any two values of x. Put them to the equation of a line and calculate the values of y.

for x = 0:

$y=\dfrac{1}{5}(0)+4=0+4=4\to(0,\ 4)$

for x = 5:

$y=\dfrac{1}{5}(5)+4=1+4=5\to(5,\ 5)$

Find the rate of change for a linear function that passes through the points (-5, 1) and (1, 10).

Lyrx [107]

The slope of the function for rise/run would be 3/2, this is because;
The function passes through (-5,1) and (1,10). Lets find the change on the y and x axis.
For the x axis;
-5 to 1.
That is a change of positive 6.
-5+6=1
For the y axis;
1 to 10.
That is a change of positive 9.
1+9=10
For the slope we must put rise (change in y axis) over run (change in x axis) to get 3/2 when simplified from 9/6.
For every 2 units of rise in the x axis the y axis rises by 3.

The surface area A of a cube is equal to the sum on the areas of the 6 square faces that form the cube. If each face has side le

algol [13]

Answer:

18 units

Step-by-step explanation:

Hello, I can help you with this.

Step 1

identify

we have a equation, let's look it

A=6s2

The surface area A of a cube=6(area of a face)

area of face= side*side

Area=6*side*side

Step 2

isolate side from the equation

$side^{2}=\frac{Area}{6}\\side=+\sqrt{\frac{Area}{6}}$

we are looking for a distance, so , we will use only the positive root

Step 3

replace the value of 1944 square units into the equation

$side=+\sqrt{\frac{Area}{6}}\\side=+\sqrt{\frac{1944}{6}}\\side=\sqrt{324}\\\\side=18\\$

so, the value x of a side of a cube with a total

the side of a cube is 18 units when the surface area of the cube shown is 1944 units2

Have a good day.
