Find the slope and the equation of the line through the points (-4,9) and(8,12)

lianna [129]

The formula for a slope is $\frac{y_2 - y_1}{x_2 - x_1}$ . Inserting those values into the equation, we get (12 - 9) / (8 - (-4)) = 3/12 = 1/4

Dr. W Sweet Rides Car Rental charges a flat fee of $24 and an additional $0.35 for every mile the car is driven. Which function

murzikaleks [220]

Answer:

$c = 0.35 x + 24$

Step-by-step explanation:

First, let's go over the information we have. We know that no matter what, Dr. W Sweet will charge a base fee of $24, and that for each additional mile, he will charge 35¢. Now let's make an equation reflecting this information:

cost = 35¢ (number of miles) + $24 (starting fee)

We can also write this like this:

$c = 0.35x + 24$

If you want to test this equation, put in a value for the x variable, like so:

Value: 25 miles

$c = 0.35(25) + 24 \\ c = 8.75 + 24 \\ c = 32.75$

For this situation, the cost will be $32.75. I hope this helps! If you have questions, comment on this response, I should write back reasonably quickly.

The area of a square is represented by the expression 16x^4y^8. What is the length of each side of this square

Leona [35]

Answer: $4x^2y^4$

Step-by-step explanation:

Given

The area of the square is $A=16x^4y^8$

Suppose a is the side length of the square

The area of the square is given by

$\Rightarrow A=(\text{side length})^2$

So, we can write

$\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4$

length of each side is $4x^2y^4$

What is the median of the following set of numbers?

Gnesinka [82]

21, 45, 121, 300, 312, 333, 347, 421, 614,

The median is the middle number of a data set therefore you need to arrange the data is order from smallest to largest as I have done above. Then you need to find the number in the middle which is 312 in this case by finding the number which has the central position (position 5 in this case) of the data set. If there are an even number of numbers in the data set, you add them together and divide by 2 though that is not necessary this time as there are an odd number of numbers.
