Answer:
A number, such as 10 is a composite number because it is even.
The first answer, answer A. It's easy.
Slope intercept form is y = mx+ b
So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!
Let's do it!
- add 3x to the right side of the equation
<u>5y - 3x + 20 = 0</u>
<u>5y + 20 = 3x </u>
- move 20 to the right side
<u>5y = 3x - 20 </u>
- Divide both sides of the equation by 5
y = 3/5x - 4
This is our answer!

The correct answer is d.We have the following system of linear equations:
(I)

(II)

Let's use the elimination method, then let's multiply the equation (1)

and subtracting (I) and (II):
(I)

∴

(I)

(II)

____________________
(III)

∴

We can find the value of x by substituting y either in (I) or (II). Thus, from (I):

∴

∴

∴

∴

Let's substitute the values of x and y into (I) and (2)
(I)

(II)

Finally the answer is:
