Natalie added 20 pieces of candy to a bowl. Two days later, half of the candy in the bowl is gone. If there are 14 pieces left i
Salsk061 [2.6K]

Answer:

8 pieces of candy

Step-by-step explanation:

Take the original amount of candy in the bowl to be x.

It says that 20 pieces of candy were added, therefore there are x+20 pieces of candy in the bowl.

Half of the candy is gone, therefore \frac{x+20}{2} pieces of candy are left in the bowl.

After half of the candy is gone, there are 14 pieces left, so we can say that \frac{x+20}{2} =14

Solve for x:

x+20 = 28

x=8

Which is the equation for line AB
miskamm [114]

The equation for line AB would be x = -5 but It looks like it is asking for line AD.

The equation of line AD can be written in slope-intercept form y=mx+b, m being the slope and b the y intercept.

The y intercept would be point D since it is on the y axis. The y intercept would be (0,6) or 6 in the equation.

The slope can be calculated by the slope formula which is m = y2-y1/x2-x1

For the slope form we have to plug in both points A and D

6-1 over 0+5 y x

The slope is y/x and 6-1=5 and 0+5=5. This means that the slope is 5/5 or just 1. Now that we have the slope, we can form the equation y=x+6.

Since we have to turn it into standard form, we move x to the other side of the equation using Subtraction property of equality to get as the final answer

-x+y=6
