Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1)
-2-(-1)
-1-1
Then that would give you -1/-2 so technically -1/2<< this is what you graph

Describe one difference between rewriting a literal equation and solving an equation in one variable.
sesenic [268]

Literal equation:

we know that

literal equation is equation of more one variable

for example: 2x+3y=1

And we can solve such equations only if we are given two such equation

because it has two variables

One variable equation:

such equation has single variables

for example:

3x=21

we don't need any other equation

we can solve for variables from single equation itself

because it has only one variable that is x

Select the correct answer. What is the domain of the function f(x) = 2x + 5?
lawyer [7]

The domain of the function is the complete set of possible values of the independent variable. (−∞,∞),{x|x ∈ R}

<h3>What is the domain function?</h3>

The domain is the set of values for which the given function is defined.

The given function;

f(x) = 2x + 5

The domain of the given function is all real numbers except where the function is undefined.

In this case, there is no real number that makes the function undefined.

The domain of the function is the complete set of possible values of the independent variable.

(−∞,∞),{x|x ∈ R}

The range is the set of all valid y values.

Solve for x in the figure below
fredd [130]

Answer:

x = 35.4

Step-by-step explanation:

Sum of all interior angles in a triangle = 180°

Therefore:

(x + 2)° + (2x + 2)° + (2x - 1)° = 180°

x + 2 + 2x + 2 + 2x - 1 = 180

Collect like terms

x + 2x + 2x + 2 + 2 - 1 = 180

5x + 3 = 180

Subtract 3 from each side

5x + 3 - 3 = 180 - 3

5x = 177

Divide both sides by 5

5x/5 = 177/5

x = 35.4
