This table gives a few (x,y) pairs of a line in the coordinate plane

Mathematics
1 answer:
umka21 [38]3 years ago

Answer:

-41

Step-by-step explanation:

Use 2 points to find the equation of the line using the 2-point form of the equation of a line. Then we write the equation in the slope-intercept form to find the y-intercept.

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

We can use points (-36, -117) and (-27, -98), so

x1 = -36

x2 = -27

y1 = -117

y2 = -98

y - (-117) = \dfrac{-98 - (-117)}{-27 - (-36)}(x - (-36))

y + 117 = \dfrac{19}{9}(x + 36)

y + 117 = \dfrac{19}{9}x + 76

y = \dfrac{19}{9}x - 41

The y-intercept is -41.

10 out of every 65 students order pizza for lunch. There are 416 students at her school. How many students will eat pizza at her
Studentka2010 [4]

Answer:

64

Step-by-step explanation:

First, you divide 416 by 65. This gets you 6.4. But it's not 1 in 65 eating pizza, it's 10 out of 65, so then you multiply 6.4 by 10, getting 64.

Lulu wants to get fit. She started with 50 laps a day and she intends to add 10 laps every week. Write a mathematical expression
vlabodo [156]

Answer: 10x + 50

Step-by-step explanation:

lets say that x is equal to the amount of weeks that she runs. She starts off the first week with 50

Then, since she is adding 10 every week, you would do 10x, or 10 times the amount of weeks that she runs.

Since you originally started with 50, you have to add the 50 to the 10x.

So you get...

<h3>10x + 50</h3>

For example

on week 2, if you plug in 2 to x you get

10(2) +50

20 + 50

70 laps after the second week

Solve the following quadratic equation.
Nonamiya [84]

Given:

Consider the given equation is

(x-18)^2=1

To find:

The values of x.

Solution:

We have,

(x-18)^2=1

Taking square root on both sides, we get

x-18=\pm\sqrt{1}

x-18=\pm 1

Adding 18 on both sides, we get

x-18+18=\pm 1+18

x=\pm 1+18

Now,

x=1+18 and x=-1+18

x=19 and x=17

Therefore, the correct option is A.
