The answer is C. A way to find out is to add a few numbers from that group being specified. If you add 2 or even 100 to 3, the answer will be odd. If you add 12 to 3, you will get 15 which is a composite number. If you were to add 2 to 3, you will get 5 which is an odd number.

Answer & Step-by-step explanation:

In order to find the y-intercept of this equation, we must turn this equation into a slope-intercept equation. The equation for slope-intercept form is <em>y=mx+b. </em>We can do this by using these steps. Our goal is to get y by itself on one side.

6x - 2y - 9 = 0

Step 1: Add 9 on both sides of the equation.

6x - 2y = 9

Step 2: Subtract 6x on both sides of the equation. Once you subtract, make sure you put the -6x in front of 9 so we are following the rules of variables and exponents.

-2y = -6x + 9

Step 3: Divide -2 on both sides of the equation.

y = 3x - \frac{9}{2}

So, the y-intercept is -\frac{9}{2}

A metal worker has several 1-kilogram bars of a metal alloy that contain 23% copper and several 1-kilogram bars that contain 79%
astraxan [27]

Answer:

30 each of 23% bars and 18 each of 79% bars

Step-by-step explanation:

If x is the number of 1 kg 23% copper bars, and y is the number of 1 kg 79% copper bars, then:

x + y = 48

0.23x + 0.79y = 0.44(48)

Substituting and solving:

0.23x + 0.79(48-x) = 0.44(48)

0.23x + 37.92 - 0.79x = 21.12

16.8 = 0.56x

x = 30

y = 48 - x

y = 18

You need 30 each of 23% bars and 18 each of 79% bars.
