Answer:
-u-
Step-by-step explanation:
Use the slope-intercept form to find the s l o p e and y-intercept.
S l o p e: 2
y-intercept: (0,-1)
Since you mentioned the fundamental counting principle, I assume you are looking for the total number of possibilities.
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
Answer:
Solve equation [2] for the variable z
[2] z = -x + 3y
// Plug this in for variable z in equation [3]
[3] 2x - 2•(-x +3?) = 18
[3] 4x = 18
// Solve equation [1] for the variable x
[1] x = 2y + 1
// Plug this in for variable x in equation [3]
[3] 4•(2?+1) = 18
[3] 0 = 14 => NO solution
Hint: Try using the Pythagorean thereom to solve it.
