Answer:
The correct answer is (5,3)
Step-by-step explanation:
I just did that one:)
Equation:
y - 10 = -5x
Solve:
(y - 10) + 10 = (-5x) + 10
y = -5x + 10
Remember the formula (Slope Intercept Form):
y = mx + b
m = Slope (Rise/Run)
b = Y-intercept
So your graph would look something like the attached image:

Answer: A'(-3, 7), B'(3, 6), C'(-7, -2)
Step-by-step explanation:
Reflecting over y = x maps (x,y) onto (y,x).
Answer:
The correct answer would be, No of bracelets the company must sell to break even would be 15
Step-by-step explanation:
Revenue is given by the function as:
R(x) = 20x
and Cost is given by the function as:
C(x) = 180 + 8x
Let the function P(x) represent the profit earned.
We know that Profit is equal to Revenue - Cost
i-e
Profit = Revenue - Cost
So,
P(x) = R(x) - C(x)
Now substituting the Revenue and cost values in the above equation.
P(x) = 20x - (180 + 8x)
P(x) = 20x -180 -8x
P(x) = 20x - 8x -180
P(x) = 12x - 180
Now if we want to find out the break even point, we would consider profit as Zero, 0. So substituting 0 in the above equation for Profit, we will get:
0 = 12x - 180
12x = 180
x = 180/12
x = 15
So the break even point will be 15 bracelets.
