9. You have a record of your age x (in years) and your height y (in inches) on

Rashid [163]

Answer:

Step-by-step explanation:

The y's can be a duplicate and g(x) can still be a function. Since travelling back in time is not possible, all most all ages along the x axis will produce a function as long as x>0.

It doesn't have to be much over 0 to start counting it. As soon as birth occurs height can be measured and usually is.

Given the graph of a line y=−x. Write an equation of a line which is perpendicular and goes through the point (8,2).

coldgirl [10]

Answer:

y = x - 6

Step-by-step explanation:

The slope of y = -x is -1, so the slope of any line perpendicular to y = -x is +1. Thus,

y = mx + b becomes 2 = 1(8) + b, so that b = -6.

The desired equation is y = x - 6.

Check: Does (8,2) lie on this line? Is 2 = 8 - 6 true? YES.

kow [346]

Answer: They are similar many ways.

Step-by-step explanation:

1. There is a law that guides both of them. Because each has a strick law.

2. They both need practice. Practice they say makes one perfect. When u practice both of them, you become familiar on how to use them.
