What is the value of p if the line that passes through (2,-4) and (p,8) has a slope of 1/2?

Irina18 [472]

Answer:

Step-by-step explanation:

(2,-4)....x1= 2 and y1 = -4

(p,8).....x2 = p and y2 = 8

slope(m) = 1/2

now use the slope formula (y2 - y1) / (x2 - x1) and sub in what we know...

slope(m) = (y2 - y1) / (x2- x1)

1 / 2 = (8 - (-4) / (p - 2)

1 / 2 = (8 + 4) / (p - 2)

1/2 = 12 / (p - 2) .....now multiply both sides by (p - 2)

1/2(p - 2) = 12

1/2p - 1 = 12

1/2p = 12 + 1

1/2p = 13

p = 13 / (1/2)

p = 13 * 2/1

p = 26

so the value of p is 26

You buy x bottles of soda for $1.50 using a gift card that you got as a reward for getting good grades

nadya68 [22]

Answer:

$0\leq x \leq 10$

Step-by-step explanation:

The function is $f(x)=15-1.50x$ where x is the number of bottles of soda.

The domain means the set of "allowed" x values.

Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:

$f(x)=15-1.5x\\0=15-1.5x\\1.5x=15\\x=\frac{15}{1.50}\\x=10$

This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>

$0\leq x \leq 10$
