Determine the value(s) for which the rational expression 2x^2/6x is undefined. If there's more than one value, list them separat

Dmitry [639]

Answer:

Step-by-step explanation:

Hello, dividing by 0 is not defined. so

$\dfrac{2x^2}{6x}$

is defined for x different from 0

This being said, we can simplify by 2x

$\dfrac{2x^2}{6x}=\dfrac{2x*x}{3*2x}=\dfrac{1}{3}x$

and this last expression is defined for any real number x.

Thank you

2x + 5y= 18 4x + 20y= -36 Solve and Explain first to get right gets brainliest

Jet001 [13]

because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18

(2x+10y)-(2x+5y)=-18-18

5y=-36

then y=-7.2

because 2x=18-5y

so x=(18-5y)/2=(18-5*(-7.2)）/2=27

A Math professor scores all tests with a maximum of 100 points. A student must have an average of 90 on six tests to receive an

nignag [31]

Answer:

No, he cannot

Step-by-step explanation:

Lets say the student takes the maximum socre on his last test, so he gets 100. Now, his average on the six texts will be:

(75+85+90+95+94+100)/6 = 89.83

So, if taking 100 is not enough to get to the average of 90, this means he would need a score greater than 100, which is impossible as 100 is the maximum. So, the student CAN'T get an A

What is 4/3 subtracted by 2/5

Tomtit [17]

Here is you're answer:

In order to find the answer you have to find the common denominator and then subtract.

$\frac{4}{3} - \frac{2}{5}$
Find the common denominator:
$CD = 15$
$4 - 2 = 2$
$=\frac{2}{15}$

Therefore you're answer is "2/15."

Hope this helps!
