Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)

Step-by-step explanation:

Self explanatory question, you set a quadratic equation to zero

For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0

Then, you would factor, that equals to (x – 8)( x + 2) = 0

(X-8)=0 (X+2)=0

X+2=0

-2 =-2

X=-2

X-8=0

+8 =+8

X=-8

To check you would simply plug in the values into the quadratic equation. They would both equal 16=16

:) Multiple choices are difficult but the best answers are C or D GO WITH YOUR GUT!

Nezavi [6.7K]

Answer: They are away for $2\dfrac{3}{4}\ hours$ from home.

Step-by-step explanation:

Since we have given that

Time to get there = $\dfrac{1}{4}$

Time to get back = $\dfrac{1}{4}$

Number of soccer games = 3

Time for each soccer games = $\dfrac{3}{4}$

So, total time for 3 games would be

$3\times \dfrac{3}{4}=\dfrac{9}{4}$

So, the time for which they will be away from home is given by

$\dfrac{1}{4}+\dfrac{9}{4}+\dfrac{1}4}=\dfrac{1+9+1}{4}=\dfrac{11}{4}=2\dfrac{3}{4}\ hours$

Hence, they are away for $2\dfrac{3}{4}\ hours$ from home.

ale4655 [162]

Answer: 72

Step-by-step explanation:

From the question, we are informed that a disc jockey can play 7 records and that there are 9 records to select from for a particular segment of a radio show.

The number of ways that the program for the segment be arranged will be:

= 9! / 7!

= (9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (7 × 6 × 5 × 4 × 3 × 2 × 1)

= 9 × 8

= 72
