Using the line of best fit, it is found that the predicted length of a catfish that weighed 36 pounds is of 36 inches.

A linear function is modeled by:

y = mx + b

In which:

In this problem, the line passes through points (20,4) and (29,22), hence the slope is given by:

m = (22 - 4)/(29 - 20) = 2.

Then:

y = 2x + b.

Point (20,4) is replaced in the equation and used to find b, hence:

4 = 2(20) + b

b = -36

Then the equation is given by:

y = 2x - 36.

When the weight is of 36 pounds, x = 36, hence the prediction is of:

y = 2(36) - 36 = 36 inches.

Answer:

c. 4

Step-by-step explanation:

see how many cubes are already there. Then, subtract that answe from 12 to get how many you need.

Answer:

Count the units in total shown here:

There are 2 units both in the back and front.

So double of 2 means 4 units, there are 4 units on the back and front.

Now count the units between them:

There are 4 units across from them.

Add the units together:

4 + 4

= 8, there are 8 units in total shown in this figure.

But, we need to find how many more units should be added to these 8 units to get a result of 12 units altogether.

So, subtract the 8 units from the 12 units to get the remaining units you would need to add to 8 units to get 12.

12 - 8

= 4, you would need 4 more units so that this figure would have a volume of 12.

C. translated down 2 units

---The "-2" located on the outside of f(x) tells us that the y-values are being changed. With that, the graph can be moved up or down. The presence of the negative/subtraction sign tells us that the graph is moved down.

D. translated right 4 units

---The "-4" located with the x in f(x) tells us that the x-values are being changed. The only tricky thing about this is that the direction of the movement is actually the opposite of the sign. So with the negative/subtraction sign, the graph is moved to the right instead of the left.

Hope this helps!

Answer: Idealistically, you can write many numbers here, but for the sake of simplicity, I'll say... -7.60.

Step-by-step explanation: This isn't much in terms of written work, it's more mental math. When we're looking for a number greater than a negtaive number, but it still has to be negative, it will be less than the first number. So, what can be less than -7.81, anything -7.80 and above before you get to -7. The higher the number in the negative scale, the smaller it is. The lower the number on the negative scale, the larger it is. So make the number larger than -7.81, and less than -7.

Answer:

I'm sorry I don't understand you can give me anything other than math

The quantity of NOx the vehicle will release in 15 years for running 22000miles each year will be 458700 grams.

Multiplication is an operation that represents the basic idea of repeated addition of the same number.

here in the question we will multiply the Nox released by the vehicle per year to 15 years.

Given that: Vehicle releases 1.39 Nox per mile

Now if vehicle is running 22000 miles per year so the Nox released per year will be =22000x1.39=30580 grams per year

For 15 years the NOx released by the vehicle will be = 30580x15=458700 grams

Hence the quantity of NOx the vehicle will release in 15 years for running 22000miles each year will be 458700 grams.
