X+90+61=180 ( the sum of the three angles in a triangle is 180 °)
x+151=180°
x=180-151
x=29°
For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function

Answer:
1200 copies
Step-by-step explanation:
In order to find how many copies can be printed in 10 minutes, first we need to find how many copies the machine can print in one minute. Let that be x.
480= 4x
Divide both sides by 4
120=x
Now, we need to multiply that by how many minutes we need to find.
120* 10= 1200
Thus, the machine can print 1200 copies in 10 minutes.
