The table and the graph each show a different relationship between the same two variables, x and y:A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,180 and 4,240 and 5,300 and 6,360. On the right of this table is a graph. The x axis values are from 0 to 10 in increments of 2 for each grid line. The y axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2, 70 and 4, 140 and 6, 210 and 8, 280 is drawn.

How much more would the value of y be in the table than its value on the graph when x = 11?

Answer:

Answer:

The value of y be in the table is 275 more than its value on the graph when x = 11.

Step-by-step explanation:

The slope represent the changer is y with respect to change in x.

Slope=(y_2-y_1)/(x_2-x_1)

From the table it is noticed that the value of y increased by 60 as the value of x increased by 1. Therefore the slope of the function is 60. It is also calculated by the formula. The two points from the table are (3,180) and (4,240).

Slope=(240-180)/(4-3)=60

The point slope form is,

y-y_1=m(x-x_1)

The equation of function is,

y-180=60(x-3)

y-180=60x-180

y=60x

Put x=11

y=60* 11=660

Therefore the value of table is 660 at x=11.

The two points from the graph are (2,70) and (4,140).

Slope=(140-70)/(4-2)=35

The equation of line is,

y-70=35(x-2)

y-70=35x-70

y=35x

Put x=11

Therefore the value of line is 385 at x=11.

The difference between values of y at x=11 is,

660-385=275

Therefore the value of y be in the table is 275 more than its value on the graph when x = 11.

Which numbers should be multiplied to obtain 175^2 − 124^2?51 and 299

51 and 51

30501 and 30749

2601 and 2601

Answers

you have to multiply 51 and 299 you will gets 15249 wich is the same as 175^2 - 124^2

Your Answer:

A.) 51 and 299

Step-by-step explanation:

In order to find out what other numbers are multiplied to obtain x, our unknown value, we must first square 175² - 124². 175² is equal to 30625 and 124² is equal to 15376. When we subtract 30625 and 15376, we get 15249. Now that we have found out our once unknown value, we will multiply the numbers from the list of choices to see which to values lead up to the product 15249. After multiplying 51 and 299, we find that they equal 15249, our desired answer.

Hope this helps y'all :D

- 3x + 8y = 5
6x - 2y =10

Answers

Let us solve this system by substitution.

-3x + 8y = 5
6x - 2y = 10

According to equation 2,

6x - 2y = 10

6x = 10 + 2y

thus, x = 10 + 2y / 6

substituting the value of x in equation 1,

-3 ( 10 + 2y / 6) + 8y = 5

-30 - 6y + 8y = 5 x 6 = 30

-30 + 2y = 30

2y = 60

Thus, y = 30.

Substituting the value of y in equation 2,

6x - 2y = 10

6x - 2(30) = 10

6x - 60 = 10

6x = 70.

Thus, x = 70/6.

Thus, x = 70 / 6     ( and y = 30)
