Answer:
x = 15
Step-by-step explanation:
3x / 3 = 45 / 3 x = 15
The shape is a parallelogram because the length of the sides based on the coordinates
I think it would be 54 words per minute
36÷2=18 which is 1/3 of a minute so we multiply 18 by 3 to get how many words in one minute, 18×3=54
Answer:
B.
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define function</u>
f(x) = 8x + 4
<u>Step 2: Prep</u>
- Rewrite: y = 8x + 4
- Swap <em>x</em> and <em>y</em>: x = 8y + 4
<u>Step 3: Find Inverse (Solve for </u><em><u>y</u></em><u>)</u>
- Subtract 4 on both sides: x - 4 = 8y
- Divide both sides by 8: (x - 4)/8 = y
- Rewrite: y = (x - 4)/8
- Rewrite: f⁻¹(x) = (x - 4)/8
