Profits are simply the difference between the selling price and the cost price of an item.
The expression that represents the total profit is 3850x - 22100
The profit (p1) on the first item is given as:
The profit (p2) on the second item is given as:
So, the total profit (p) on the sales of both items is:
Substitute known values
Collect like terms
Hence, the expression that represents the total profit is 3850x - 22100

Hope that helped!!! k
There is no solution. if you are using the two equations to solve for y and x.
you can plug one equations into the other.
substituting one of the y gives...
3(x+4)=3(x-4)
÷ both sides by 3 gives x+4=x-4
get x on one side and numbers on the other
x-x =4+4
and x-x will give you a 0 for the left side
therefore 0 = 4+4.. not true.
Answer:
y = -4x + 19
Step-by-step explanation:
The line parallel to y = -4x + 1 would have the same slope of -4. The coefficient of x will be -4. We can put this into the equation y = -4x + a where <em>a</em> is the y-intercept and a ≠ 1. Now solve for <em>a</em>.
y = -4x + a
plug in 4 for x and 3 for y
3 = -4(4) + a
simplify
3 = -16 + a
+16 both sides
19 = a
a = 19
y = -4x + 19
