The answer is a. the first step is to divide the whole bottom equation by -1 because x can’t be negative. you then plug in y + 9 into the first equation to solve. so the equation would be (y + 9) + y = 11. you do this because in substitution you plug in one of the equations into the other equation. you then get 2y + 9= 11. you would next subtract 9 to both sides which leaves you with 2y= 2, divide by both sides, y = 1. you then plug the why value into the first equation to figure out the value for x. so it would be x + 1 = 11, subtract 1, x equals 10.

sorry this was hard to explain! hope this helps!

The parking space shown at the right has an area of 209 ft2. A custom
jeyben [28]

Given:

The parking space shown at the right has an area of 209 ft².

A custom truck has rectangular dimensions of 13.5 ft by 8.5 ft.

To find:

Whether the truck fit in the parking space or not?

Solution:

If the area of the truck is more than the area of the parking space, then the truck cannot fit in the parking space otherwise it will fit in the parking space.

The area of a rectangle is:

Area=length\times width

Area of the rectangular truck is:

Area=13.5\times 8.5

Area=114.75

The area of the truck is 114.75  ft² which is less than the area of the parking space, 209 ft².

Therefore, the truck can fit in the parking space because the area of the truck is less than the area of the parking space.

Please help! Identify the rule! Will give brainiest!!
pychu [463]

Answer:

  y = 3x -1

Step-by-step explanation:

When x goes up 2 units from 5 to 7, y goes up 6 units, from 14 to 20. That's 3 times as many units as the change in x.

When x goes up 4 units from 7 to 11, you goes up 12 units, from 30 to 32. That's 3 times as many units as the change in x.

So, the slope of the function is constant at 3. If y were 3x exactly, the output numbers would be 15, 21, 33, each of which is 1 higher than the actual output. Hence the output must be one less than 3x, or ...

  y = 3x -1

to find 1,188 divided by 12. I think about 1,200 divided by 12 that's groups 100of 12. 1,188 has fewer group of 12
Sergio [31]

To find 1,188 divided by 12. I think about 1,200 divided by 12 that's groups 100 of 12. 1,188 has fewer group of 12

Answer: If we divide 1200 by 12, we will get 100 12's in 1200.

But our question is 1188 divided by 12.

So the difference between 1200 and 1188 is 12. Therefore there will be 99 12's in 1188.

Therefore, 1188 divided by 12 is 99.

Also I have shown in the image attached how 1188 divided by 12 is 99.
