If f(x) is parallel to the line y=3/4x +2/5 which function could be f(x)?

The condition that 2 or more than 2 lines are parallel, is to have the SAME SLOPE.

So the line that is parallel to y=3/4(x) +2/5 is y = 3/4(x) +b
You can repace b by any number, you will always have a parallel line to the original function

F(x) must also have a slope (m) of 3/4, because parallel lines share a slope in linear functions (y=mx+b), so any answer that begins with 3/4x could be f(x).

-7x + 6x + 8 = x - 10<br> Solve for x pls

Art [367]

-x + 8 = x - 10
8 - x = x - 10
8 = x - 10 + x
8 = 2x - 10
8 + 10 = 2x
18 = 2x
18/2 = x
9 = x
x = 9

Can someone help with math?

algol [13]

Answer:

A. {4,3}

Step-by-step explanation:

x -2y = -2

y = - 3x +15

x - 2(-3x+15) = -2

x +6x - 30 = -2

7x = 28

x = 4

y = - 3x +15 = - 3*4 + 15 = -12 + 15 = 3

What is 4p-13p-p=-150 More 2 step equations. I don't get this one at all

raketka [301]

4p-13p-p=-150
-9p-p=-150
-10p=-150
<u>p=15
Order of operations. Doing so turns it into a simple division equation.</u>

At the local college, a study found that students earned an average of 14.8 credit hours per semester. A sample of 94 students w

ozzi

Answer:

By the Central Limit Theorem, the best point estimate for the average number of credit hours per semester for all students at the local college is 14.8.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of the sample:

14.8 credit hours per semester.

By the Central Limit Theorem, the best point estimate for the average number of credit hours per semester for all students at the local college is 14.8.
