Answer:

The midpoint is (3,8)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the two coordinates together and divide by 2

( 4+2)/2 = 6/2 = 3

To find the y coordinate of the midpoint, add the two coordinates together and divide by 2

( 7+9)/2 = 16/2 = 8

The midpoint is (3,8)

Divide<br> 4^2 divided by 4^6 =

alekssr [168]

Answer:

Step-by-step explanation:

so you are saying do:

$4^{2} /4^{6}$ which is 16 /4096

16/4096=0.00390625

<u>another way you can do this is</u>

$4^{2} /4^{6}$

just subtract the powers

2-6=-4

so the answer is $4^{-4}$

Write a rule for the linear function in the table.

JulijaS [17]

Answer:

I guess that you want to know the transformations:

We start with:

f(x) = y = 4*x + 3

a)the transformed function is:

f(x) = y = -4*x - 3

So the sign changed.

This means that we go from (x, y) to (x, - y)

This is a reflection over the x-axis which changes the sin of the y component.

b) Now we go to f(x) = 4*x + 3

So the coefficient in the leading term changed.

This is a horizontal contraction:

A horizontal contraction of factor K for the function g(x) is: g(K*x)

In our case, we have:

f(K*x) = 4*(k*x) + 3 = x + 3

4*k*x = x

4*k = 1

k = 1/4

Then the transformation is an horizontal contraction of scale factor 1/4.

It takes 1 1/3 hours to set up 1/3 of an hour to run and 2/3 of an hour to verify the results. How many hours will it take to co

liraira [26]

Answer: It will take $\frac{7}{3}$ of an hour to complete the test.

Step-by-step explanation:

We need to convert the mixed number $1\ \frac{1}{3}$ to an improper fraction:

$1\ \frac{1}{3}=\frac{(1*3)+1}{3}= \frac{4}{3}$

Now, we need to make the following add the fractions in order to calculate how many hours will it take to complete the test. Then, we get:

$\frac{4}{3}+\frac{1}{3}+\frac{2}{3}=\frac{4+1+2}{3}=\frac{7}{3}$

Therefore, it will take $\frac{7}{3}$ of an hour to complete the test.

Q # ..19 anybody help me?

Goshia [24]

The equation of the line with slope m and passing through the point $(x_0,y_0)$ is

$y-y_0=m(x-x_0).$

Since m=6 and the coordinates of the point are (8,3), then the equation is

$y-3=6(x-8).$

Answer: correct choice is B.
