Y=3x<br>2y-5x=4 <br>I need the work and answer for it

telo118 [61]

U plug in the y
2 (3x) -5x=4
simplify
6x -5x =4
solve
x=4
so now you know x=4 so plug that in for x
y= 3(4)
y=12
check your answer
2(12)-5(4)=4
solve
24-20=4
4=4
so you now you got the answer right !

hope that helps!

A normal distribution has a mean 20 and standard deviation 5. What is the z score that corresponds to the value x=222

sashaice [31]

Answer: The z score that corresponds to the value x=22 is 0.4 .

Step-by-step explanation:

Given : A normal distribution has a mean 20 and standard deviation 5.

i.e. $\mu=20$

$\sigma=5$

Let x be the random selected variable.

We know that to find the z-score corresponds to the value x is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 22, we have

$z=\dfrac{22-20}{5}=\dfrac{2}{5}\\\\\Rightarrow\ z=0.4$

Hence, the z score that corresponds to the value x=22 is 0.4

The slant asymptote of f(x)=x^2-4x+1/2x-3 is y=1/2x-5/4 <br> t or f

sveta [45]

Answer:

True

Step-by-step explanation:

Given that a function is

$f(x)=\frac{x^2-4x+1}{2x-3}$

We are to find the slant asymptote if any for this function

Since numerator is of degree 2 and denominator 1, let us divide and then check

Doing long division we find

$f(x)=\frac{1}{2} [x-\frac{5}{2} ]-\frac{11}{4(2x-3)}$

Thus we find the asymptote y= the quotient obtained i.e

$\frac{1}{2} [x-\frac{5}{2} ]\\=\frac{x}{2} -\frac{5}{4}$

Hence asymptote is

$y=1/2x-5/4$

Statement given is true.
