I have to say this is wrong because you subtracted 3 and 3 is the variable term. So what you need to do is to add 9 to both side to get 3x by it self. Then divide by 3 and then x=6

How can you graph m(x)=5x and then compare it to f(x)=x?

erastovalidia [21]

Graph the line y=5x. Then graph the line y=x. Then look at them and describe in what ways they are the same or different.

Fill in the missing information. Tim Worker is doing his budget. He discovers that the average miscellaneous expense is $45.00 w

nlexa [21]

Answer:

$P(38.6$

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

$z=\frac{X -\mu}{\sigma}$

And replacing we got:

$z=\frac{38.6- 45}{16}= -0.4$

$z=\frac{57.8- 45}{16}= 0.8$

We can find the probability of interest using the normal standard table and with the following difference:

$P(-0.4$

Step-by-step explanation:

Let X the random variable who represent the expense and we assume the following parameters:

$\mu = 45, \sigma 16$

And for this case we want to find the percent of his expense between 38.6 and 57.8 so we want this probability:

$P(38.6$

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

$z=\frac{X -\mu}{\sigma}$

And replacing we got:

$z=\frac{38.6- 45}{16}= -0.4$

$z=\frac{57.8- 45}{16}= 0.8$

We can find the probability of interest using the normal standard table and with the following difference:

$P(-0.4$

svp [43]

Answer:

-2.8h-26+5d

Step-by-step explanation:

So just combine like terms

For the h, you’d get -2.8

For the d, you’d get 5

For the normal integer, -26

The complement of a right angle is an obtuse angle. true or false.

Genrish500 [490]

False because the obtuse angle is to large to complement the right angle to diffrent angles can not be both of their compliments
