Determine whether each function is even, odd, or neither. g(x) = |x-3| neither g(x) = x + x² neither
Lelechka [254]

Answer:

So, both the functions are neither even and nor odd.

Step-by-step explanation:

A function is even if g(x) = g(-x) and odd if g(x) = - g(x).

g(x) = |x-3|

g (-x ) = | -x -3 |

So, the function is neither even and nor odd.

g (x) = x + x²

g (- x) = (- x) + (- x) ² = -  x + x²

So, the function is neither even and nor odd.

What is 7/2 divided by 49/4?
ruslelena [56]

Answer:

\frac{2}{7}

Step-by-step explanation:

\frac{7}{2} ÷ \frac{49}{4} needs to be flipped and multiplied.

It will become \frac{7}{2} · \frac{4}{49}.

Simplify the fractions by replacing 7 with 1 and 49 with 7, since 7 is 1/7 of 49. Then, turn the 2 into a 1 and the 4 into a 2, since 2 is half of 4.

You will be left with 1 · \frac{2}{7}, which equals \frac{2}{7}

A parallelogram has one angle that measures 90°. What are the measures of the other three angles in the parallelogram?
k0ka [10]

Answer:

All the others are 90 degrees too

Step-by-step explanation:

In a parallelogram opposite angles are congruent. Also in a quadrilateral the sum of angles is 360 degrees. since their are two pairs of congruent angles you could make an equation and it would look like this: 180+2x =360. x would be 90 making every angle 90 degrees
