Answer:
The answer in decimal form is 18.9 so if you convert it to a fraction, the correct answer should be 8 9/10.
17! I think. If you have 15 students that speak French they could all be bilingual!
The slope is zero because the line is not moving
Answer:
Step-by-step explanation:
a) What point would be the Center of the circle C (above)? C
b) What line segment would be the Radius? BC
c) What line segment would be the Diameter? AD
d) What line Color is representing the Circumference? Dark Blue/Black?
e) What number represents the ratio of Circumference/Diameter? π
f) if the radius is 5 meters, what is the distance of the circumference?
5π ≈ 15.707... m
With graphs on paper you can visually see intersecting lines(one solution), identical lines
(infinite solutions), or parallel lines(no solutions).
This method works best for lines that have integers for solutions. The task of determining rational or irrational solutions from graphs is difficult.
The substitution method usually must be used for equations with higher exponents. The deawback of this method is having to work with fractions.
The elimination method is often the method of choice.
This method however requires that you learn to recognize when the systems produce parallel lines or have equations that represent the same lines.
