Direct variation describes a simple relationship between two variables . We say y varies directly with x

This means that as x increases, y increases and as x decreases, y decreases

Given equation is y = kx,

if x is doubled,

so plug in x = 2x in the given equation so new y1 will become

y1 = k ( 2x)

y1= 2kx

y1 = 2 y

So y becomes doubles

According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?

natta225 [31]

$P(A | B) = \frac{P(A \cap B)}{P(B)}$

$P(A|B) = \frac{5/7}{7/8}$

$P(A|B) = \frac{5}{7} \div \frac{7}{8}$

$P(A|B) = \frac{5}{7}\times\frac{8}{7}$

$P(A|B) = \frac{5*8}{7*7}$

$P(A|B) = \frac{40}{49}$

The formula for electrical power is P, is P= I^2 R, where I is current and R is resistance. The formula for I in terms of. P and

Butoxors [25]

Ans

I = sqrt(P/R)

Step-by-step explanation:

You divide both sides by R first

P/R = I^2 R/R

So,

I^2 = P/R

take the square root of both sides

I = sqrt(P/R)

If 5x – 4 = 31, what is the value of x?

Lunna [17]

Answer:

x = 5 $\frac{2}{5}$

Step-by-step explanation:

Hi there!

So, to answer this problem, I'll use the reverse method.

31 - 4 = 27,

So how many times, can 5 go into 27?

The closest factor of 5 to 27 is 25.

5 can go in to 27, 5 times.

Continuing on, there is a 2 left over, so the answer to your question is

x = 5 $\frac{2}{5}$

5 · 5 $\frac{2}{5}$ - 4 = 31

Let me know if I am incorrect and I will attempt to find the right answer for you.
