Find the x-intercept and y-intercept

Mathematics
1 answer:
Aneli [31]3 years ago
8 0

Answer:

x - intercept:  (-22, 0)

y - intercept: (0, 11)

Step-by-step explanation:

Given the linear equation

-3x + 11y = 66

<em><u>Determining the x-intercept</u></em>

We know that the x-intercept can be computed by setting the value y=0 and solving for x.

substitute y = 0

-3x + 11y = 66

-3x + 11(0) = 66

-3x + 0 = 66

-3x = 66

Divide both sides by -3

-3x/-3 = 66/-3

x = -22

Thus, the ordered pair representing the x-intercept : (-22, 0)

<em><u>Determining the y-intercept</u></em>

We know that the y-intercept can be computed by setting the value x=0 and solving for y.

substitute x = 0

-3x + 11y = 66

-3(0) + 11y = 66

0 + 11y = 66

11y = 66

Divide both sides by 11

11y/11 = 66/6

y = 11

Thus, the ordered pair representing the y-intercept : (0, 11)

Therefore, we conclude that:

x - intercept:  (-22, 0)

y - intercept: (0, 11)

What are the two words that allow you to check your division problem backward?
Dahasolnce [82]

Answer:

inverse operation

Step-by-step explanation:

Inverse means opposite. The opposite of division is multiplication. For example, if you divided 15 by 3, the answer is 5. If you multiply 5 by 3, the answer is 15. You know your answer is correct by checking it with the inverse operation.

Hope this helps!! Have a wonderful day :3

HELP QUICK !’ ***What is the area of a circle with a diameter of 126 in?
Vladimir79 [104]

Answer:

49,850.64

Step-by-step explanation:

To find the area of a circle, you must use the formula pi r ^2 (pi r squared).

In this case, we are using 3.14 for pi, so we can add that into the formula.

3.1r^2

We also know the radius, so we can add that in too.

3.14 x 126 ^2

Now solve.

126^2 = 15,876

15,876 x 3.14 = 49,850.64

49,850.64 is the answer.

Hope this helped!
