Our system of equations is:
y = x - 4
y = -x + 6
We can solve this system of equations by substitution. We already have one equation solved for the variable y in terms of x, so we can substitute in this equivalent value for y into the second equation as follows:
y = -x + 6
x - 4 = -x + 6
To simplify this equation, we first are going to add x to both sides of the equation.
2x - 4 = 6
Next, we are going to add 4 to both sides of the equation to separate the variable and constant terms.
2x = 10
Finally, we must divide both sides by 2, to get the variable x completely alone.
x = 5
To solve for the variable y, we can plug in our solved value for x into one of the original equations and simplify.
y = x - 4
y = 5 - 4
y = 1
Therefore, your final answer is x = 5 and y = 1, or as an ordered pair (5,1).
Hope this helps!
I think it would be a one in six chance of happening 1/6, because there are only 6 sides
To my calculation, i think it will be 9 peach pies
Answer:
24 inches
Step-by-step explanation:
Pattern for the length is time 6.
Do 6 x 4, which will equals 24
Our Answer is- 24 inches.
Another way:
6 - 10 = +6
12 - 18 = +6
18 -24 = +6
Therefore- 18 - 24 = +6
24 Inches
Answer:
The number of days is approximately 8.
Step-by-step explanation:
Given : A medical scientist has a 15-gram sample of I-13, And would like to know it's half-life in days. he also knows that k=0.0856.
To find : The half-life, in days, of I-131 using the information at the left?
Solution :
The decay model is given by 
We have given that,
The substance's half-life is the time it takes for the substance to decay to half its original amount.
i.e. 
The value of k is k=0.0856.
Substitute the values in the formula,
Taking natural log both side,
Therefore, The number of days is approximately 8.
