Answer:

C) 50

Step-by-step explanation:

You first look at the 40 given to you. Then you know the angle opposite of it will be 40 also because of the law that opposite angles are the same. Once you have two angles in the triangle you can add 40 plus 90 in which you get 130 but that does not equal 180. So you can see that angle 1 is 50 because 50 and 130 equals 180.

Say that xyz is your number, then y=4z and x+3=y

Since it is a multiple of 4, y has to be 4 or 8, which means z has to be 1 or 2, since it is 1/4 of y and then since x is 3 less than y, x would have to be 1 or 5...so the numbers are....141 or 582

Simplify the expression above

Answer:

3x^2 + 2x - 3y - 10

Step-by-step explanation:

7y + 2x - 10y +3x^2 - 10x

I like to put it in order starting with exponents like this

3x^2 + 2x - 10x + 7y - 10y

then combine like terms

3x^2 - 8x - 3y

that is as simplified as it gets.

Answer:

(10,0)

Step-by-step explanation:

When it comes to rotations by 90 degrees or 270 degrees, you just have to switch the order of x- and y- coordinates. Then find the sign by considering which quadrant will it be. In this case, it is originally on the positive y-axis and now it would be +ve x-axis.
