If two functions are inverse of each other, they are basically switching the x- and y-axes.
Take for example, p(x)=2x, is a line passing through the origin with a slope of two. Its inverse, q(x)=x/2, is a line passing through the origin with a slope of 1/2, the reciprocal of 2. If you plot the two lines, you will notice that the two lines are symmetrical about y=x, or a 45 degree line from the x-axis.
This also explains y=x (which lines on the line of reflection) has its inverse also equal to y=x!
Answer:
a) y=650x+0
b) 24,000=650x
24,000/650=x
x=37
I hope this is good enough:
if you can you don't have to put the +0 its just to fill it all out
I’m pretty sure it’s ‘a’ sorry if wrong
Answer: 30 percent of people who do not brush theit teeth every night.
Step-by-step explanation:
Given : 7 out of 10 people brush their teeth every night.
That means 3 out of 10 people do not brush their teeth every night. (7-10=3)
Now, the percent of people who do not brush their teeth every night =
Hence, 30 percent of people who do not brush theit teeth every night.
