Answer:
x = 4/3; y = 11/3
Step-by-step explanation:
y = -x + 5 and 5x + 2y = 14
Since the first equation is already solved for y, we can use the substitution method.
Substitute y of the second equation with -x + 5.
5x + 2y = 14
5x + 2(-x + 5) = 14
5x - 2x + 10 = 14
3x + 10 = 14
3x = 4
x = 4/3
Now we substitute x of the first equation with 4/3 and solve for y.
y = -x + 5
y = -4/3 + 5
y = -4/3 + 15/3
y = 11/3
Solution: x = 4/3; y = 11/3
Salary option 1
salary: $115×52 weeks=$5980
commission: $125,000×0.095=$11,875
total: $5980+$11,875=$17,855
Salary option 2
salary: $450×52 weeks=$23,400
Difference
$23,400-$17,855
=$5545
Clearly, y = 4x.
_____
The cost is proportional to the number of bags, so you really only need one point to determine the constant of proportionality. The point (1, 4) will tell you directly what the cost of 1 bag of peanuts is.
Answer:
The equation is:
Step-by-step explanation:
Given the endpoints of a side of a rectangle
Finding the slope
Using the point-slope form of a line equation
substituting the values m = -1 and the point (1, 6)
Thus, the equation is:
