I first used substitution to get my answer and then used graphing to check. You can easily get a graphing equation by rearranging the second equation.<span />
Answer:
7/10 = 63/90
4/9 = 40/90
Step-by-step explanation:
Rewriting input as fractions if necessary:
7/10, 4/9
For the denominators (10, 9) the least common multiple (LCM) is 90.
LCM(10, 9)
Therefore, the least common denominator (LCD) is 90.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
7/10 = 7/10 × 9/9 = 63/90
4/9 = 4/9 × 10/10 = 40/90

Using the product rule, which states that (uv)' = u'v + uv':
If y = (e^-2x)(sec3x)
y' = (e^-2x)'(sec3x) + (e^-2x)(sec3x)'
y' = -2(e^-2x)(sec3x) + (e^-2x)(3 sec3x tan3x)
y' = 3(e^-2x)(sec3x tan3x) -2e^-2x (sec3x)
This matches choice B.
Stem-and-Leaf-plot represents data by separating each value into two parts. Dot plot uses a graph in which each data value is plotted as a point along a horizontal scale of values. The difference is Dot Plots use graphs to organize data and Stem-and-Leaf plot separates the data into two parts
