OLEGan [10]

Answer:

r

Step-by-step explanation:

Since r is not given, the length we can be find using the Law of Sines using is length r.

The Sine formula or the Law of Sines

q/Sine Q = r/Sine R

q=9.5

r is the unknown

9.5/Sine 18° = r/ Sine 135°

each of the variables a, b, c, d, e and f represents a different positive real number. given the equations below, which variable
slega [8]

Answer:

The greatest value is "e"

Step-by-step explanation:

We have the following equations:

a. 1.31 a = f

b. 1.12b=f

c. 1.01c=f

d. 0.98d=f

e. 0.31e =f

Then solving for "a", "b", "c", "d" and "e" we have:

a. a = f /1.31

b. b=f/1.12

c. c=f /1.01

d. d=f / 0.98

e. e=f / 0.31

Now, given that in all the equations "f" represents the same number, the gratest value it's going to be the option in which "f" is divided by the smaller number.

The option in which f is divided by the less number is option e because, in this case, f is divided by 0.31.

2: Write out a system of equations that has infinite solutions. Explain why it has infinite
Rasek [7]

Answer:

Below!

Explanation:

A system of equations with infinite solutions defines that both the equations are identical and are overlapping when the lines are graphed. An example could be y = 5x + 9 and y = 5x + 9. These sets of equations have infinite solutions because they are the same and when graphed, they overlap.
