-1/5(x-4)=-2 how do you solve this equation

m_a_m_a [10]

Multiple both sides by 5/1 and get

-1/1 • (x-4) = -10/1

divide the numbers and get

-1 • (x-4) = -10

remove the parentheses

- x-4 = 10

move the constant to the right

-x = -10-4

calculate

-x = -14

change the signs

x= 14

Can someone help me find the midpoint?

ioda

Answer:

(6,-2.5)

Step-by-step explanation:

The formula for the midpoint between two points is:

$(\frac{x_{1} + x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

Now we substitute

We have than (9, -1) is $(x_{1}, y_{1})$ and (3, - 4) is $(x_{2}, y_{2})$

So:

$(\frac{(9) + (3)}{2},\frac{(-1)+(-4)}{2})\\\\(-1) + (-4) = -5\\9 + 3 = 12\\$

So, we have:

$(\frac{12}{2}, \frac{-5}{2})\\\\12 / 2 = 6\\-5 / 2 = -2.5\\\\(6, -2.5)$

I can do a graphic explanation if you want.

4 letters are typed, without repetition. What is the probability that all 4 will be vowels? Write your answer asa percent. Round

Marysya12 [62]

There are 26 letters in the alphabet, 5 are vowels, therefore, the probability of choosing a vowel the first time is:

$\frac{5}{26},$

and the second time is:

$\frac{4}{25}\text{.}$

Continuing with this reasoning, we get that the probabilities each time are:

$\frac{5}{26},\frac{4}{25},\frac{3}{24},\frac{2}{23}\text{.}$

Finally, the probability that you get all vowels is the product of the probabilities:

$\frac{1}{2990}\text{.}$

Writing the above result as a percentage we get:

$0.033\%.$

Answer:

$0.033\%\text{.}$
