Answer:

A. {3,4}

Step-by-step explanation:

In order to find the x values which would make the entire function undefined, you would have to factor the bottom equation. Factoring x^2+7x+12 gives you (x+3)(x+4). If you set each of these equal to 0, you end up with the x values being 3 and 4.

If five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?
tensa zangetsu [6.8K]

Answer:

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

Answer:

half a slice = 0.55 $

In the above figure, m AOC=26 and m BOD= (2x+39). If AOC and BOD are vertical angles whats the value if x?
Reika [66]

If AOC and BOD are vertical angles, the value of x is x = -6.5

<h3>How to determine the value of x?</h3>

The angles are given as:

m AOC = 26

m BOD = (2x+39).

From the question, we have

AOC and BOD are vertical angles

Vertical angles are equal.

So, we have:

AOC = BOD

Substitute the known values in the above equation

2x + 39 = 26

Subtract 39 from both sides

2x = -13

Divide bot sides by 2

x = -6.5

Hence, if AOC and BOD are vertical angles, the value of x is x = -6.5
