Answer:
-18

Answer:

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
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.
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
✳︎ ✳︎ ✳︎ ✳︎ ✳︎ ✳︎ 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! :)
