Please help with 3! i don’t know how to graph it or work it out
seraphim [82]

Answer:

The graph is attached.

Step-by-step explanation:

\frac{2}{x} + \frac{y}{4} = \frac{3}{2}

\frac{y}{4} = -\frac{2}{x} + \frac{3}{2}

Multiplying both sides by 4 gives;

y = \frac{-8}{x} + 6

You can graph this solution using a graphing calculator to get the answer as attached.

Find the length of side xx in simplest radical form with a rational denominator.
borishaifa [10]

Answer:

x = 3sqrt(2)/2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

The two legs are equal, x

x^2 + x^2 = 3^2

2x^2 = 9

Divide each side by 2

x^2 = 9/2

Take the square root of each side

sqrt(x^2) = sqrt(9/2)

x = sqrt(9)/ sqrt(2)

x = 3 / sqrt(2)

x = 3 sqrt(2) / sqrt(2)*sqrt(2)

x = 3sqrt(2)/2

Find the greatest common factor of 15x2y3 and -18x3yz.
olganol [36]

For this case we have that by definition, the GFC (greatest common factor) of two numbers is given by the greater number that is a factor of both numbers. Then, let:

15x ^ 2y ^ 3\\-18x ^ 3yz

We decompose into factors:

15: 1,3,5,15

18: 1,2,3,6,9,18

The GFC is 3.

So, we have that the GFC of the expressions is:

3x ^ 2y

Answer:

3x ^ 2y

Step-by-step explanation:

Mission Information :

This question is incomplete this line is missing in the question " Rin reaches into the bag, pulls out a blue marble, and puts it in her pocket. Then Misaki reaches in and pulls out a marble. What is the total number of possible outcomes for Misaki’s marble"

Now coming to the solution ,

Given :

Red marbles=3

blue marbles=5

green marbles=2

yellow Marbles=8

Total number of outcomes can be determined by

=Red marbles + blue marbles + green marbles + yellow Marbles

= 3\ +\  5+2 +8=18

As mention in the given question the Rin is pulling the 1 marble ,Now Total number of outcomes

=18-1\\=17

Therefore 17 is the correct answer
