Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.

Answer:
45.6°
Step-by-step explanation:
The attached result was found by typing "arccos(7/10) in degrees" into a web browser search box.
Your calculator can give you the same result. The inverse cosine function often shares a key with the cosine function. It is often marked as cos⁻¹. Be sure that the angle mode is set to degrees, not radians.
A is the correct answer. We all know that 100 is divisible by 4, so any multiple of 100 is also divisible by 4 (ex. 500, 1500, etc.)z Therefore, any number can be divisible by 4 regardless of what is in the hundreds place and above. What counts is the last two digits of the number, the tens and ones places. For example, let's look at 334 and 324. 34 is not divisible by 4, therefore 334 is not divisible by 4. 24 is divisible by 4, therefore 324 is divisible by 4. Check in a calculator for proof!
To build the graph that represents the function

you have to put two points (x, y): (-2, 0) and (0, -4). Then just draw the line across these points like that:
