It's a Rational and Integer. Because it's a decimal it can't be anything else.
Answer:
3x +4 = -2x -1
Step-by-step explanation:
The line that goes up to the right has a y-intercept of +4. This is where it crosses the y-axis. It's slope (rise/run) is 3/1 = 3, so its equation in slope-intercept form is ...
y = mx +b . . . . where m is the slope, b is the y-intercept
<u>y = 3x +4</u>
The other line has a negative slope and a y-intercept of -1. The slope of that line is rise/run = -2/1 = -2, so its equation is ...
<u>y = -2x -1</u>
__
The solution point will have the x-coordinate that is the solution of the equation ...
y = y
3x +4 = -2x -1 . . . . . . substituting the above expressions for y.

Answer:
(C)11.72+[(0.2)(11.72)]
(D)(1.2)(11.72)
Step-by-step explanation:
From the table:
The Total =$11.72
They would like to tip the server 20 percent. Therefore, their total bill will be :
![11.72+(20\%$ of 11.72)\\=11.72+[(0.2)(11.72)]](https://tex.z-dn.net/?f=11.72%2B%2820%5C%25%24%20of%2011.72%29%5C%5C%3D11.72%2B%5B%280.2%29%2811.72%29%5D)
We can also re-write this by factorizing as shown below:
![11.72+[(0.2)(11.72)]\\=11.72[1+0.2]\\=(1.2)(11.72)](https://tex.z-dn.net/?f=11.72%2B%5B%280.2%29%2811.72%29%5D%5C%5C%3D11.72%5B1%2B0.2%5D%5C%5C%3D%281.2%29%2811.72%29)
The correct options are C and D,
