Here is the answer, the summation of the angles inside any triangle = 180 . Also, the same thing for any angles for straight line = 180.
I need help on 2 and 3 please

2. A 3. A 2 times x is 2x, 2 times y is 2y; therefore it is 2y +2x 2 times 3x is 6x, there is no possible way for the answer to be 5x
if you multiply the outside number by all the terms in the parenthesis you'll get; 2(x + y) = 2(x) + 2(y)= 2x + 2y giving you A as your answer in Q.#2. And for Q.#3 the its the same steps; 2(3x) = 2(3)(x) = 6xGiving you A as your answer cause; 5x is not equivalent and the others are equivalent to 6x by multiplying as I explained you. hope that helps :D
I am so confused on functions! Please help!
Answers
Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like f(x)=23y-5 (that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise.
What does it mean for an equation to express y in terms of x
Answers
This is also known as constant of variation.
So, lets give an example
y = 4 and x = 2
If y = 8, what does x equal?
4*2 = 8 y = 8
x = 2 2*2 = 4
x = 4
We solve for the missing value based on the other value.
