Answer:

Step-by-step explanation:

A triangle always has 180° so that means 40° (2x+9)° and another angle add up to 180°.

We can find out two angles in order to find out the third, one of them is 40° the other is 180°-105° because there are 180° on a line.

you get 75.

75°+40°=115°

180°-115°=65°

2x+9=65°

Make x the subject of the formula:

2x=56

(take away 9)

x=28

(divide both sides by 2)

What are the domain and range of the function f(x) = 3x + 5

fredd [130]

Step-by-step explanation:

Here,let x = 1,2,3 and 4

Then,

Domain =(1,2,3,4)

Again,

f(1)= 3*1 + 5

=3 + 5

f(2)=3*2 + 5

=6 + 5

=11

f(3)=3*3 + 5

=9 + 5

=14

f(4)=3*4 + 5

=12 + 5

=17

Therefore, Range=(8,11,14,17)

Whats the answer to x^3 y^0 z^-2

Elina [12.6K]

Answer:

$\frac{x^3}{z^2}$

Step-by-step explanation:

There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.

As we all know that any variable or number to the power of 0 is equal to 1. This means that $y^0 = 1$ .

We also know that a negative power can bring the variable down and make it a fraction. This means that $z^-^2=\frac{1}{z^2}$

Now that we got these two sorted we are able to write it in a simplified form.

Answer: $\frac{x^3}{z^2}$
