F(x)=3x-2 what is the x intercept

1 answer:

5 0

So the equation basically is 3x-2=y. The x intercept is when y is 0. We need to move the equation so it equals x.

3x-2=y
Let's add 2 to both sides.
3x=y+2
Now divide.
(y+2)/3=x

Let's make y=0.
(0+2)/3
2/3=x

So, the x intercept is (0,2/3). We could even look on a graph (below).

A penny, nickel, and dime are simultaneously flipped. What is the probability that heads are showing on at least 6 cents worth o

Nastasia [14]

Answer:

5/8

Step-by-step explanation:

The number of possible outcomes after flipping 3 coins is $2 \times 2 \times 2 = 8$. If the dime isn't heads, we need both the penny and nickel to be heads. If the dime is heads, the other two could be anything. So there are a total of $1+(2 \times 2)=5$ ways for us to get at least 6 cents. The answer is $\boxed{\dfrac58}.$
