Answer:
200 muffins
Step-by-step explanation:
The selling price of each muffin = $2
The cost price of each muffin = $1.40
The price of electricity = $120
If the number of muffins that Jenny sells in a day is x, then, Jenny's total cost in a day is:
120 + (1.4 * x) = 120 + 1.4x
and the total sales earnings in a day for x muffins will be:
2 * x = 2x
To break even, the total costs in a day must equal to the total earnings. That is;
![2x = 120 + 1.4x](https://tex.z-dn.net/?f=2x%20%3D%20%20120%20%2B%201.4x)
Solving this:
![2x - 1.4x = 120\\\\\\0.6x = 120\\\\\\x = 120/0.6\\\\\\x = 200](https://tex.z-dn.net/?f=2x%20-%201.4x%20%3D%20120%5C%5C%5C%5C%5C%5C0.6x%20%3D%20120%5C%5C%5C%5C%5C%5Cx%20%3D%20120%2F0.6%5C%5C%5C%5C%5C%5Cx%20%3D%20200)
She must sell 200 muffins in a day to break even.

Answer:
Step-by-step explanation:
f-1(x) is the inverse of f(x)
to find the inverse let’s set the equation up like this
y = 4x -2
now we’ll switch x and y
x = 4y -2
and solve for y
x + 2 = 4y
x/4 + 2/4 = y
the inverse is
y = x/4 + 1/2
this equation is written in y = mx + b form
where b = y intercept
so the y intercept is 1/2
Answer:
Step-by-step explanation:
1. (sq root of) a^2 if a>0 => √(a^2) = ±a
2. (sq root of) 36x^2 if a>0 => ±6x
