Answer: The equation has a positive y-intercept
This is because the constant is +10
If you decrease something by 4 percent,
you are keeping (100% - 4%) or 96% of the original
so multiply by the original amount by 96 percent or .96
If you have 100 pennies, and you give 4 away ( 4 percent decrease), you still have 96 pennies. You are keeping 96 percent of what you started with. This works no matter how much you start with.
Example:
you have 40 dollars
4% decrease
40 * .04 = 1.6 take this away
40 - 1.6 = 38.4 left
you keep 96 percent
40 * .96 = 38.4 left
Answer:
37.89051724=x
Step-by-step explanation:
We can use similar triangles and proportions to solve. Put the same side of the small triangle over the large triangle.
MA MB
------- = ----------
MN MP
80.5 -35 x
------------- = ----------
70.5 96.6 -x
Simplifying
45.5 x
------------- = ----------
70.5 96.6 -x
Using cross products
45.5 (96.6-x) = 70.5x
Distribute
4395.3 - 45.5 x = 70.5x
Add 45.5x to each side
4395.3 - 45.5 x+45.5x = 70.5x+45.5x
4395.3 = 116x
Divide each side by 116
4395.3/116 = 116x/116
37.89051724=x
