Answer:

solve for X

17-4x=33

-4x=33-17

-4x=16

-4x/-4=16/-4

x=-4

Step-by-step explanation:

1. move the constant (17) to the right side

2. subtract the numbers on the right side (33-17)

3. Divide both sides of the equation by -4 (/4)

4. write the answer x= -4

Solved.

Identify the function in which y varies directly with x
ZanzabumX [31]

Answer:

y = kx

Step-by-step explanation:

You'll need to share the possible answer choices in all future posts.  

A function in which y varies directly with x has the form

y = kx, where k is the constant of proportionality.

With more data, it'd be possible for you and me both to identify this constant.

This is AP Statistics Question. Can you help me with this?
LenKa [72]
The confidence interval is given by

\mu_s\pm Z_{\alpha_0}\sigma_s

where \mu_s is the sample mean and \sigma_s is the standard error of the mean. In turn, the standard error of the mean is \sigma_s=\dfrac\sigma{\sqrt n} where n is sample size.

We have

\sigma_s=\dfrac6{\sqrt{25}}=1.2

The endpoints of the confidence interval correspond to the finite endpoints of the rejection region. That is,

\begin{cases}\mu_s-1.2Z_{\alpha_0}=28\\\mu_s+1.2Z_{\alpha_0}=32\end{cases}

for which we can solve for Z_{\alpha_0}. We get

Z_{\alpha_0}=\dfrac53\approx1.67

which is the critical value for a confidence level of \alpha_0\approx90.44\%.

How do you write square root of 72 in algebra?
cupoosta [38]
You would have the square root symbol (called a radical) over the number 72. But if you mean to simplify it, you can keep in mind that 9 x 3 = 72 and the square root of 9 is 3, so then your answer would be

3(radical)3

Hope that's not too confusing!

5x+4y=16 -2x-4y=-4 <br>Show your step by step process.<br>Solve the system of linear equations.​
slava [35]

Answer:

x=1 and y= 5\frac{1}{4}

Step-by-step explanation:

To solve this, lets take the first equation and find the x value.

Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.

5x+4y=16

-5x       -5x

4y=-5x+16

÷4   ÷4  ÷4

y=\frac{-5}{4}+4

or

y=-1\frac{1}{4}+4

or

y= 5\frac{1}{4}

Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:

5x+4(\frac{-5}{4}+4)=16

5x-5+16=16

5x+11=16

    -11 -11

5x=5

÷5 ÷5

x=1 and y= 5\frac{1}{4}
