Suppose that y varies inversely with x, and y = 6 when x = 7. (search it on brainly and type it for the answer, I can't search o
Rainbow [258]

Answer:

k=42

Step-by-step explanation:

y ∝ 1/x

making an equation from the equation above, we can assume:

y = K/x Where k is a constant

Let's clear K

K = xy

If y = 6 when x = 7, then:

K = (7)(6) = 42

Verifying

y = K/x

y = 42 / 7 = 6

A padlock has a four-digit code that includes digits from 0 to 9, inclusive. What is the probability that the code does not cons
Eduardwww [97]
Since there is no repetition allowed, there are 10 possibilities for the 1st digit, 9 for the 2nd, 8 for the 3rd, and 7 for the 4th. This gives a total of (10)(9)(8)(7) = 5040 four-digit codes.
For all odd digits to be used, there are 5 possibilities for the 1st digit (1,3,5,7,9), 4 for the 2nd, 3 for the 3rd, 2 for the 4th. This gives a total of (5)(4)(3)(2) = 120 codes that only use odd digits.
Therefore there are 5040 - 120 = 4920 codes that do not consist of all odd digits. The probability is 4920/5040 = 41/42.

Write the equation in slope intercept form. what are the slope and y-intercept? -3x - 10y = 7
blondinia [14]
slope intercept is basically solve for y y=mx+b m=slope b=yintercept -3x-10y=7 add 3x to both sides -10y=3x+7 divide both sides by -10

Are 2 + 6x and 2(3x + 1) equivalent
Solnce55 [7]

✳︎ ✳︎ ✳︎ ✳︎ ✳︎ ✳︎ Hello There! :)

To determine whether the two expressions are equivalent, we take the second expression and distribute 2:

2(3x+1)

6x+2=2+6x

And now we know the two expressions are equivalent. If you look, you will remember the Commutative Property that states:

a+b=b+a

In this case, a=6x and b=2.

So we know that the two expressions are equivalent.

Hope this helps! :)
