Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)
Answer:
-19-28i
Step-by-step explanation:
Simplify and write the answer in standard form, a+bi.
Answer: A Domain: {-5, 0, 4, 6} Range: {-9,0, 9, 13}
Step-by-step explanation:
Domain is the x-values, least to greatest.
Range is the y-values, least to greatest.
The answer would be 15.7142857143
You can get the answer by calculating (5/7) × 22
