Answer:

x-intercept: 4

y-intercept: -12

Step-by-step explanation:

Well our formula is y=mx+b where m is the slope and b is the y-intercept. -12 takes the place of the b, so -12 is the y-intercept.

To find the x-intercept, we need to make y=0.

0=3x-12

<em>Add 12 to both sides</em>

12=3x

<em>Divide both sides by 3</em>

x=4

The x-intercept is 4 and the y-intercept is -12.

Answer:

The answer is (4, 0), (0, -12)

y = 3x - 12

x-intercept:

y = 0

0 = 3x - 12

12 = 3x

x = 12/3

x = 4

Intercept: (4, 0)

y-intercept

x = 0

y = 3 * 0 - 12

y = 0 - 12

y = -12

Intercept: (0, -12)

Help me please!!!<br> Determine whether the given number belongs to each set

nata0808 [166]

The given number $-34\frac{3}{8}$ is not a whole number, It is a Integer and Rational number.

<h3>What are Whole Numbers?</h3>

The complete set of natural number with entity '0' is called whole number.

For example: 0, 1, 2, 3, 4, and so on.

<h3 /><h3>What are Integer ?</h3>

Integers are the real number but they can be positive, negative and zero.

For example: -2, -5, -8, 0, 1, 54, 66 etc.

<h3>What are Rational Numbers?</h3>

Rational numbers are those which have a numerator and denominator.

For example: 2/5 here, 2 is numerator and 5 is denominator.

Here, we have given the number as $-34\frac{3}{8}$

it can be solved using - ( 34 x 8 + 3 ) / 8

now, the number becomes

→ - ( 272 + 3 )/8

→ - 275/8

It is not a whole number, it is a integer and it is a rational number too.

Hence,

The given number $-34\frac{3}{8}$ is not a whole number, It is a Integer and Rational number.
