Answer:

s = -2400t + 17400

Step-by-step explanation:

Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.

Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.

The length of a rectangle is represented by x+3 and the width by 2x-4. Write an expression for the area of this rectangle
madam [21]

Answer:

2x² +2x - 12

Step-by-step explanation:

area of rectangle = length X width

length = x+3

width = 2x - 4

Area = (x+3)(2x-4)

        = x(2x-4) +3(2x-4)

        = 2x² - 4x + 6x - 12

        = 2x² +2x - 12

Audrey uses 5/8 cup of Fruit in each smoothie she makes 6 smoothies to share with her friends how many cups of fruit does she us
olga55 [171]
To find the amount of cups of fruit used you must multiply the number of smoothies (6) by the amount of fruit need for each smoothie (5/8)
6 x 5/8 = 30/8
30/8 can be simplified to 15/4.
This is still an improper fraction, because the numerator is higher than the denominator. To fix this, you divide 15 by 4, which equals 3 3/4 cups

Water pressure increases 0.44 pounds per square inch (0.44 psi) with each increase of one foot in depth below sea level. Identif
prohojiy [21]

Answer:

Depth below sea level is the independent quantity,

Water pressure is the dependent quantity

Step-by-step explanation:

An independent quantity is a variable that can be changed in an experiment. While, dependent quantity results from the independent quantity or we can say, that depends upon the independent quantity.

Here,

The water pressure increases 0.44 pounds per square inch (0.44 psi) with each increase of one foot in depth below sea level,

So, for measuring the water pressure we took depth below sea level as a variable,

⇒ Depth below sea level is the independent quantity,

While, with increasing depth by 1 foot the pressure is also increase by 0.44 pounds per square inches ⇒ pressure depends upon the depth

⇒ Water pressure is the dependent quantity.
