When you have a bag of chips and you have to divide among different people.
The value of x and y in the given equation is determined -1 and -2 respectively.
<h3>
Value of x and y</h3>
The value of x and y can be determined by solving the two equations simultaneously.
y = -2x - 4 ----- (1)
y = 4x + 2 ----- (2)
solve (1) and (2) together
-2x - 4 = 4x + 2
-6x = 6
x = -1
y = 4(-1) + 2
y = -4 + 2
y = -2

Answer:
x = -3, 6
Step-by-step explanation:
First, add 18 to both sides
x² - 3x - 18 = 0
+ 18 + 18
x² - 3x = 18
Add 9/4 to both sides because that is the square of half of -3
x² - 3x + 9/4 = 18 + 9/4
Multiply both sides by 4 to get rid of the fractions
(x² - 3x + 9/4 = 18 + 9/4)4
4x² - 12x + 9 = 72 + 9 = 81
Factor the left side of the equation
(2x - 3)² = 81
√(2x - 3)² = √81
Because of the square root, this will result in a positive number and a negative number
2x - 3 = 9
2x - 3 = -9
For both equations, add 3 to both sides then divide by 2
2x - 3 = 9
+ 3 +3
2x = 12
2x/2 = 12/2
x = 6
2x - 3 = -9
+ 3 + 3
2x = -6
x = -3
3rd quadrant. Below is a picture that explains what is positive and in what quadrant. I use the term <em>All students take calculus</em>. If you start in the 1st and go through 2nd, 3rd and forth:
A in all stands for All positive
S in students stands for sin and its inverse (csc) is positive.
T in take stands for tan and its inverse (cot) is positive.
C in calculus stands for cos and its inverse (sec) is positive.
The answers are A., C., and E.
The chart shows that Camila has a greater rate of change than Lydia, so B is incorrect. C and E are true because the graph shows that Camila's rate of change is $7/hour, making C true, which means that in 2 hours, she gets paid $14, making E true.
Answers: A., C., and E.
Hope this helps! :)
