I forget all my vocabulary so hopefully someone else can correct me if the words I use aren't correct. But the following is definitely a function. "Although two x values correspond to a singular y value, the function passes a vertical line test. Meaning that it is ok to have values of x that equal the same y values, however two values of y assigned to the same x value would make the function undefined."

Hope this helps! The only vocabulary in this that you would really need is "corresponding," and (if you learned about it, you may not have yet) "vertical line test"

What's the answer? Plz explain.

Remark

Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.

Solution.

The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.

When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.

When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.

So the answer is C <<<<< Answer.

When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.

The answer is 45 because on the bottom there is a 105 and since the 30 degrees is equal with the one across from it you do 180-105-30 or 105+30 then 180-135

Solve for x 33x+10=5-2x

nignag [31]

Our equation: 33x + 10 = 5 - 2x

Step 1:

To solve for x, we need to remember to isolate the variable (that is our way to solve for x). To do that, we add 2x on the right side of the equation to cancel -2x out. Then, we add 2x on the left of the equation. The equation becomes:

$35x+10=5$
