Answer:

x = 34

Step-by-step explanation:

This is a right angle. This means that the square to the bottom right is 90 degrees. There is also an angle that is 124, but that is a linear pair to the angle on the inside. This means that 124+__=180 degrees

180-124= 56

So now we know 2 angles, which are 90 degrees and 56 degrees. Because we know that the sum of the angles of a triangle equal 180 degrees, we can subtract 90 and 56 from 180 to get our answer, 34.

Select the point that is a solution to the system if inequalities yx^2-6
labwork [276]

Answer:

The correct answer is A.

A(0,-2)

Step-by-step explanation:

Method 1

You just have to plot each point on the graph.

The one that falls within the solution region is the correct choice.

From the graph, A(0,-2) falls within the solution region.

See graph

Method 2

If you substitute the points into the inequalities, the only point that will satisfy both inequalities simultaneously is A.

The first inequality is

y\:

If we substitute A(0,-2), we get;

-2\:


-2\:


This statement is true.

The second inequality is

y\:>\:x^2-6

If we substitute A(0,-2), we get;

-2\:>\:(0)^2-6

This gives,

-2\:>\:-6

This statement is also true.

How do u do this?? What’s the answer???
V125BC [204]

Answer:

A. c = 0.31b

Step-by-step explanation:

$7.44 = 24 juice bottles

[Divide by 24 on both sides]

$0.31 = 1 juice bottle

The cost is equal to the amount per juice bottle times the number of juice bottles, so:

c = 0.31b

(A trick to use when you don't know the answer: If there are multiple answers with the same numbers but the decimal places are in different places, it is probably one of those answers.)
