28/5, you cross multiply so 4/5=y/7 would become 5y=28 then you solve for y from there which becomes 28/5

PLEASE HELP!!!!!! 100 POINTS!!!!!!!!

FrozenT [24]

Answer:

Answers are below

Step-by-step explanation:

Hour 0 1 bacterium

Hour 1 3 bacterium

Hour 2 9 bacterium

Hour 3 27 bacterium

Hour 4 81 bacterium

Hour 5 243 bacterium

Hour 6 729 bacterium

After 24 hours, the number of the bacterium will reach 282,429,536,481.

B) This table represents exponential growth because of the number of bacterium always being multiplied by 3.

C) The reason that any number to the zero power is one is that any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

D) Y = 1 + 3 to the power of x

E) The rule would change by having all of the numbers multiplied by 100 since there is 100 bacterium at Hour 0.

At a price of $9 per box of oranges, the supply is 320,000 boxes and at a price of $8.50 per box, the supply is 270,000 boxes. F

We want to find a linear equation that models the given situation.

The solution is p = $0.0001*q - $23

The general linear equation is:

p = m*q + c

Where m is the slope and c is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope can be written as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Here we have the two points:

price = $9, boxes = 320,000

price = $8.50, boxes = 270,000

We can rewrite these as:

(320,000 , $9)

(270,000 , $8.50)

Then the slope of the line will be:

$m = \frac{\$ 9 - \$ 8.50}{320,000 - 270,000} = \$ 0.00001$

Then the line is something like:

p = $0.0001*q + c

To find the value of c we can use one of the two given points, I will use the first one, (320,000 , $9).

Replacing that in our equation we get:

$9 = $0.0001*320,000 + c

$9 - $0.0001*320,000 = c = -$23

Then the linear equation is:

p = $0.0001*q - $23

Find the midpoint of the line segment with endpoints (-9,-1,) and (7,0)

creativ13 [48]

Answer:

The midpoint is;

(-1,-0.5)

Step-by-step explanation:

To do this, we shall use the midpoint formula

That would be;

(x,y) = (x1 + x2)/2 , (y1 + y2)/2

(x1,y1) = (-9,-1)

(x2,y2) = (7,0)

(x,y)

= (7-9)/2 , (0-1)/2

= -2/2 , -1/2

= (-1, -0.5)
