Answer: Option 'A' is correct.

Step-by-step explanation :

Since we have given that

Number of medals = 2

Number of runners = 8

We need to find the number of ways to award the medals.

We would use "fundamental theorem of counting" to find the number of ways.

So, number of ways is given by

8 × 7 = 56

Hence, option 'A' is correct.

A complete table with values for x or y that make this equation true:3x+y=15

Andreyy89

Answer:

Step-by-step explanation:

The given equation is: $3x+y=15$ ,

Now, putting x=2 in above equation,

$3(2)+y=15$

$y=15-6=9$

Now, put y=3 in the given equation,

$3x+3=15$

$3x=12$

$x=4$

Putting x=6,

$3(6)+y=15$

$y=15-18$ $y=-3$

Putting x=0,

$0+y=15$

$y=15$

Putting x=3,

$3(3)+y=15$

$y=15-9$

$y=6$

Putting y=0,

$3x+0=15$

$x=5$

Putting y=8,

$3x+8=15$

$3x=7$

$x=\frac{7}{3}$

ololo11 [35]

Answer:

The answer is depending on how long he us going to rent the car. If Spencer wants to rent the car for less than 150 days, the Porsche is cheaper for that. However, if Spencer wants to rent a car for more than 150 days, the Tesla is the cheaper option.

Step-by-step explanation:

You can write both Deals in slope inter form.

Tesla: y = 25x+75

Porsche: y=50x

Remember: slope inter form is y = mb + b

"mx" being the change in y over the change in 1 or (y1-y2/x1-x2)

"b" in the formula represents the y-axis
