The sum of a number, x,and 1/2 is equal to 4. Which set of equations correctly represents x

I am pretty sure it would be 1/2 + x = 4

Step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
