If we let the number of flip-flops be x in the equation and that the cost would be y ( in terms of x) and the income would be z ( in terms of x), these equations will likely intersect each other during breakeven. That is, when the total revenue that the company will gain from sales of the flip-flops just be equal with the total cost.
You have to start with the left triangle and find the side lengths. Since it is a 45-45-90, both sides are the same. Rule for this is hyp= sqrt2 * leg
Since hyp = 6sqrt2, the leg is 6.
The leg is also the hypotenuse of the triangle on the right side.
x is the side across from the hypotenuse and it is the short leg so x = (1/2)6
x = 3
Slope intercept: y = mx + b
3y = 2x + 10
Y = 2/3x + 10/3
Perpendicular = opposite sign and reciprocal slope
Y = -3/2x + b
-10 = -3/2(10) + b
-10 = -15 + b, b = 5
Equation: y = -3/2x + 5
Answer:
x = -9
y = -8
Step-by-step explanation:
here's the solution :-
=》y = 2x + 10
=》y = x + 1
plunging the value of y from equation 1 into equation 2
=》2x + 10 = x + 1
=》2x - x = 1 - 10
=》x = -9
value of x = -9
now, plugging the value of x in equation 2, we get :-
=》y = x + 1
=》y = -9 + 1
=》y = -8
The answer is 4.25
In the first step he never distributed the 1/12 to the 18. He only distributed to the 14
