Ok, so we know one point is (4,2) and the other is (-4, 0)

Slope: -2/-8 = 1/4

y ? 1/4x + b

0 = -1 + b

b = 1

y < 1/4x + 1

The math department needs to buy new textbooks and laptops for the computer science classroom. The textbooks cost $116.00 each,

Sav [38]

Answer:

6 laptops

Step-by-step explanation:

First, find the amount spent on the textbooks:

30(116)

= 3480

Subtract this from the total amount they have to spend:

6500 - 3480

= 3020

Divide this amount by 439 to find how many laptops they can buy:

3020/439

= 6.8

Round down to 6 since you can only have full laptops:

= 6

So, they can buy 6 laptops

How many gallons are in 161.25 sq ft

nataly862011 [7]

There are none. "Square foot" is a unit of area, not volume.
Square feet are flat, and can't hold water.

If you meant to ask about 161.25 CUBIC feet, I can help you there:

(161.25 ft³) x (1,728 in³/ft³) x (1 gallon/231 in³) = <u>1,206.234 gallons</u> (rounded)

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across

nasty-shy [4]

Answer:

Domain is $[0,18]$

Average rate of change of bacteria per minute is -3333.33.

Step-by-step explanation:

Domain is the possible values of $x$ .

From the graph, it's clear that the $x$ values ranges from 0 to 18 as the end points of the graph are $(0,60)$ and $(18,0)$

So, domain of the function is $[0,18]$ .

Now, average rate of change is negative as there is bacteria decay.

Average rate of change is given as the negative ratio of y intercept to the x intercept.

Here, x-intercept is 18 and y-intercept is 60000.

So, average rate of change is given as,

$R_{avg}=-\frac{60000}{18}=-3333.33$

Therefore, average rate of change of bacteria per minute is -3333.33.

I have quiz need this question! PLS I will mark brainiest

rewona [7]

We will need to shade the region above f(x) and the region below the function g(x).

<h3>How to transform the graph into the solution set?</h3>

We have:

f(x) = x² - 2

g(x) = -x² + 5

Both of these are already graphed, and we want to transform it into:

y > f(x)

y ≤ g(x)

The first inequality means that we need to graph f(x) with a dashed line, because f(x) is not part of the solution, and then we shade all the region above f(x).

For the other inequality, we use a solid line (because the points on the line are solutions) and then we shade the part below the curve.
