This table shows a linear relationship. x: 6 12 18 24 30 y: 252 504 756 1008 1260 Based on the information in this table, which equation can be used to model the relationship between x and y

Answers

Answer:

The difference between value of y at x=11 is 385, the correct option is third.

Step-by-step explanation:

The difference between value of y at x=11 is 385, the correct option is third.

The equation of a line which passing through two points is given below,

The two points from the table are (3,240) and (4,320), the equation is,

Put x=11

Therefore according to the table the value of y is 880 at x=11.

The two points from the table are (2,90) and (4,180), the equation is,

Put x=11,

Therefore according to the table the value of y is 495 at x=11.

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

Therefore third option is correct.

expand (6y-2y+5y)9 and factor 80-10y. I will give brainliest

Answers

(6y-2y+5y)9

= 54y-18y+45y

80-10y

=10(8-y)

Answer:

45y-18y+54y & 10(8-y)

Step-by-step explanation:

For the first problem, you need to distribute the 9 to the 5y, -2y, and the 6y

If you do this and multiply the 9 by each of the terms you get:

45y-18y+54y

Now we can work on the second problem

When factoring, we have to find a common factor.

In this expression, the common factor is 10 because both 80 and 10 are divisible by 10!

So we but the 10 on the outside of the parentheses and divide 80 and 10 by 10 which gets us an answer of:

10(8-y)

If you were to distribute this, you would get 80-10y so we know it is correct

Hope this helps, have a great day, and please award brainliest!

#1 you dilate by a scale factor of 2 so you just multiply all the sides by 2 to get your answer. 15x2=30 and 8x2= 16.

#2 it is a reduction because m', s', and v' are smaller then m, s, and v

#3 the scale factor is 2/3 because you do the image over the pre-image so -2,2 / -3,3 is 2/3 same is 4,2 / 6,3 and 2,-2 / 3, -3
