Answer:
The new price is $28
Step-by-step explanation:
In order to find this, multiply the price of the fan by the markup.
$20 * 40% = $8
Now we can add the amount of the markup to the original cost.
$8 + $20 = $28
Answer:
A
Step-by-step explanation:
f(x) =³√(x+12)
Let, y=³√(x+12)
Exchanging x and y,
x=³√(y+12)
Cubing on both sides,
x³=y+12
x³-12=y
f-¹(x) =x³-12
Answer:
y - 9 = -5(x + 4)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -5
Coordinate (-4, 9) → x₁ = -4, y₁ = 9
<u>Step 2: Write Function</u>
<em>Substitute into general form.</em>
y - 9 = -5(x - -4)
y - 9 = -5(x + 4)
