Answer:

The correct option is 1.

Step-by-step explanation:

In figure 1, both the lines are coincident. It means all the points lie on the line are solutions of the system.

It means the system has many solutions and the systems share the same solution set.

In figure 2, both the line are parallel and two parallel lines never intersect each other. If the system of equations represent two parallel line, then the system of equal has no solution.

Therefore the second system represent no solution.

In figure 3, both the line intersect each other at one point. It means the system of equations has no solution.

Therefore the third system represent one solution.

Therefore the correct option is 1.

It is the graph where the two lines intersect, when they intersect there is a point where they connect, and that is your answer

You are making juice from concentrate. The directions on the packaging say to mix

mel-nik [20]

Answer:

25 can.

Step-by-step explanation:

Here is the complete question: You are making juice from concentrate. The directions on the packaging say to mix 1 can of juice with 3 cans of water to make orange juice. How many 12 fluid ounces cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?

Given: Ratio to make juice with concentrate:water is 1:3.

As required we need to prepare 200 6 ounce serving of Orange juice.

∴ $200\times 6= 1200\ ounce$

Let there be x ounce of concentrate and 3x ounce of water to make 1200 ounce of orange juice.

Now, $x+3x= 1200$

∴ x= 300 ounce

Next, lets find out how many cans of 12 ounce is required.

$\frac{300}{12} = 25\ cans$

∴ 25 cans is required to make 1200 ounce of orange juice.

Radius of 0.75 centimeters is rational or irrational

A radius of 0.75 would be rational because the decimal ends and does not repeat itself.

Write (1/3i)-(-6+2/3i) as a complex number in standard form

Eddi Din [679]

Answer:

$6+\frac{i}{3}$

Step-by-step explanation:

$\frac{1}{3\imath}-(-6+\frac{2}{3\imath})$

$\frac{1}{3\imath}+6-\frac{2}{3\imath}$

taking like terms together

$\frac{1}{3\imath}-\frac{2}{3\imath}+6$

taking LCM

$\frac{1-2}{3\imath}+6$

$\frac{-1}{3\imath}+6$

taking LCM

$\frac{-1+18\imath}{3\imath}$

splitting the term

$\frac{-1+18\imath}{3\imath}$

splitting the term

$-\frac{1}{3\imath}+\frac{18\imath}{3\imath}$

$-\frac{1\times3\imath}{3\imath \times \imath}+6$

$-\frac{i}{3\imath^2}+6$

we know that

$\imath^2=-1$

putting this value in above equation

$\frac{\imath}{3}+6$

Which is 2/3 of 18 <br>A. 27<br>B. 8<br>C. 12<br>D. 6

ahrayia [7]

Answer:

C. 12

Step-by-step explanation:

We know you have the number 18 and the fraction 2/3. The problem is we want to find out what 2/3 of 18 is. Well, if 18 divided by the denominator of that fraction (3) is 6 than we just add 6 because the question is asking for 2/3 NOT 1/3.
