X = -9, y = -3.4
You can get this by adding through and getting the x's to cancel. Then use the y value to solve for the x.
Answer:
6. X= 121
7. x= 18
8. X= 7
9. x= 31
Step-by-step explanation: do u need the steps?
I think between B and C I think B is better
God bless!! <3
The graph in the top right—-when trying to figure these out, just plug numbers in for x to find the y.
For example: plug 0 in for x on both equations—
2^0 -1=0 so you get it passing thru 0,0
0+2=2 so it passes through 0,2
If you were to find the price estimate flooring for a room, you would first find the square measurements of the room. This means you need to fine the area of the room in feet. For example, you have a perfect square room with two sides that equal 15 ft. You multiply those two sides so the estimate square footage of the room is 300 square feet.
Depending on the price of the flooring you want, you then multiply the cost of the flooring by 300 square feet to get a estimated price.
I hope this helps!
