Which of the following equations will not contain point (4, 12). explain

a. y= 3/4x + 9
b. y= -1/2x + 14
c. y= 1/2x +8
d. y= -2x + 20

for brainlest answer : )

Option C.

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have the point (4,12), therefore, to know which equation will not contain that point, you must substitute x=4 into each equation and if it contains the given point, you will obtain y=12.

2. Therefore, you have:

3. When you substitute x=4 into the equation of the option C, you obtain that y=10, therefore, that equation will not contain the point (4, 12).

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
