Answer:

The probability of rolling a factor of 9 is 1/2, or 50%.

Step-by-step explanation:

The number 9's factors are 1, 3, and 9. Three of the six sides of the cube have a factor of 9. Therefore 3/6 of the sides are factors of nine.

Simplify 3/6 to 1/2 to get a probability of 50%.

You can use the what of a quadratic equation to determine the number and type of solutions of the equation?

adoni [48]

You can use the determinant (square root) of a quadratic equation to determine the number and type of solutions of the equation.

$\sqrt{b^{2}-4ac}$ > 0 → 2 real solutions

if $\sqrt{b^{2}-4ac}$ is a perfect square, then rational sol'ns

if $\sqrt{b^{2}-4ac}$ is not a perfect square, then irrational sol'ns

$\sqrt{b^{2}-4ac}$ = 0 → 1 real solution (double root)

$\sqrt{b^{2}-4ac}$ < 0 → 2 imaginary(complex) solutions

Given the following linear functio, determine the slope of a line parallel to f(x)

andrew11 [14]

Answer:

Option C is correct.

C. 4/3

Step-by-step explanation:

Given:

The given linear function of a line.

F(x)=4/3x+2

We need to determine the slope of a line parallel to F(x)=4/3x+2

Solution:

First we compare the given function of the line with standard form of a line. $y = mx + c$

Where m = slope of the line.

And c = y-intercept

So, the slope of the line $m=\frac{4}{3}$ and y-intercept $c=2$

We know that the slope of the parallel lines are same.

Therefore, the slope of a the parallel line $m=\frac{4}{3}$ .
