<em>About how</em>
As with any graphing problem, when doing it by hand, one chooses enough points to give the general shape of the curve. In some cases, quite a few points may be required. It is often helpful to use a spreadsheet for calculating the point values. Here, we've graphed the equations using "technology"--a graphing calculator.
Answer:
6 year's old
Step-by-step explanation:
Grandma is G and Robin is R
G=7R
G+12=3(R+12)
G+12=3R+36
7R+12=3R+36
7R-3R=36-12
4R=24
R=6
Robin is 6 years old
The answer to this expression would be 1.2x
Answer:
