Hey there!!

How do we find an equation?

We will need to find the slope and the y-intercept :

How do you find slopes?

Ans - In order to find slope, we will need to use the slop formula which is

( y₂ - y₁ ) / ( x₂ - x₁ )

Now let's take two points on the graph :

I would take ( 0 , 3 ) and ( 1 , 6 )

( 6 - 3 ) / ( 1 - 0 )

3 / 1

Hence, the slope is 3

The basic equation :

y = mx + b

m = slope and b = y-intercept

slope = 3

y = 3x + b

Now, let's take a coordinate and plug in the values :

... ( 1 , 6 )

6 = 3 + b

b = 3

The final equation : y = 3x + 3

Hope my answer helps!!

What are the intercepts of 2x + 3y – 6z = 30?
ycow [4]

Intercept of equation 2x + 3y - 6z = 30 is (15, 0, 0) , (0, 10, 0) and (0, 0, -5)

<h3><u>Solution:</u></h3>

Given equation is:

2x + 3y - 6z = 30

We have to find the intercepts

Intercept are the point where equations cut the x- axis, y- axis and z- axis.

<em><u>Thus, at x- axis :</u></em>

y and z both are zero

So substitute y = 0 and z = 0 in given equation

2x + 3(0) - 6(0) = 30

2x = 30

x = 15

<h3>Thus the intercept is (15, 0, 0)</h3>

<em><u>Thus at y - axis:</u></em>

x and z both are zero

So substitute x = 0 and z = 0 in given equation

2(0) + 3y -6(0) = 30

0 + 3y + 0 = 30

3y = 30

y = 10

<h3>Thus the intercept is (0, 10, 0)</h3>

<em><u>Thus at z - axis:</u></em>

x and y are both zero

So substitute x = 0 and y = 0 in given equation

2(0) + 3(0) - 6z = 30

-6z = 30

z = -5

<h3>Thus the intercept is (0, 0, -5)</h3>

Thus, intercept of equation 2x + 3y - 6z = 30 is (15,0,0) ,(0,10,0) and (0,0,-5)

vlada-n [284]

Answer:

B. 4

Step-by-step explanation:

The cost of a customer smartphone bill can be modeled by the equation c=10g+50
Vika [28.1K]

Answer:

c=10(g+5)

Step-by-step explanation:

Given that,

The cost of customer smartphone bill is given by the equation as follows :

c=10g+50

Where

g is the number of gigabits of data the customer per month

We need to factor this cost polynomial

The common between 10 and 50 is 10

Taking 10 common. So,

c=10(g+5)

Hence, the required factor is equal to c=10(g+5).

Myra is playing a board game. After 12 turns, Myra has landed on a blue space 3 times.
maks197457 [2]

In 12 turns, she lands in a blue space 3 times.

12/3 =4

In 100 turns, it is expected that Myra would land on a blue space '100/4' times

100/4= 25

Which sums up to 25 turns
