jaime bought a jar of 50 vitamins. his two children each take one vitamin each day. the number of vitamins left in the jar after

Reil [10]

Answer:

Step-by-step explanation:

f(x) = 50 - 2x

x = 0 when the vitamins are bought and none have been taken 9 that is day 0).

So the intercept on the y axis 50 - 2(0) = 50 represents this situation ( day = 0 and number of vitamins = 50).

When all the vitamins have been taken f(x) = 0 so we have

50 - 2(25) = 0 This is the intercept on the x axis ( x = 25 days).

Use the commutative property of addition to simplify 12x - 36 - 6x.

nexus9112 [7]

$12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)$

<h2>Explanation:</h2>

The commutative property of addition states that:

$a+b=b+a$

So applying this property to our expression we have:

$12x - 36 - 6x=-6x+12x-36 \\ \\ \\ So \ here: \\ \\ a=12x-36 \\ \\ b=-6x \\ \\ \\ Combining \ like \ terms: \\ \\ 12x - 36 - 6x=6x-36 \\ \\ \\ Common \ factor \ 6: \\ \\ 12x - 36 - 6x=6(x-6) \\ \\ \\ Finally: \\ \\ 12x - 36 - 6x \ is \ simplified \ to \ 6(x-6)$
