Last one:  Symmetric with respect to the y-axis

Step-by-step explanation:

About the Y-AXIS

because  think about using a few points  x = -2, x = -1 , x = 1, x = 2

notice that  2*(-2)^4  =  2 *(2)^4

and 2*(-1)^4 = 2*(1)^4

dimulka [17.4K]

Answer:

Step-by-step explanation:

Let the angles be 4x , 5x

4x + 5x = 180   { supplementary}

      9x = 180

        x = 180/9

        x = 20

Larger angle= 5x = 5* 20 = 100

Help please...I don't get this (40 points and I'll give brainliest)
dexar [7]

A x = 0

using the law of exponents a^{0} = 1

for (6² )^ x = 1 then x = 0

B note that 6^{0} = 1 ⇒ x = 1

2 → 2^8 × 3^(-5) × 1^(-2) × 3^(-8) × 2^(-12) × 2^(28)

= 2^(8 -12 + 28) × 1 × 3^(- 5 - 8)

= 2^24 × 3^(- 13) = 2^(24)/3^(13) = 10.523 ( 3 dec. places)

4. Determine whether the statement is true or false. Prove the statement directly from the definition if it is true, and give a
natta225 [31]

Answer:

The statement is false.

Step-by-step explanation:

Let a and b represent two odd integers.

The average (A) is defined by:

A=\frac{a+b}{2}

In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.

Notice that it is easier to try to find a counterexample.

For example, a=3 and b=5

A= \frac{3+5}{2} = \frac{8}{2} = 4

The result of the average is even, therefore the statement is false.

The previous calculation is a counterexample.
