Answer:
3 adults 2 children
Step-by-step explanation:
(3 x 10) + (2 x 6)
30+12=42
The answer is x=5 or x=1/2.
For this case what you should know is that the slope of the line can be calculated as:
Tan x = sin x / cos x
The lines x = 2 and x = 3 have an angle of 90 degrees with respect to the x axis:
Tan 90 = sin 90 / cos 90 = 1/0 = inf
Therefore, both lines have a rate of change that tends to infinity.
answer
Both lines have the same slope (infinity) Both are greater than m = -1
Answer: - 60i - 14j
Step-by-step explanation:
- 18i + 16j - 42i - 30j = - 60i - 14j
ANSWER
(-2,-1)
(3,14)
EXPLANATION
The given system is


or

Equate both of them:

This implies that,


x=-2 or x=3
When x=-2, y=y=3(-2)+5=-1
(-2,-1) is a solution.
When x=3 , y=3(3)+5=14
(3,14) is also a solution.
