Answer:
third option
Step-by-step explanation:
time ('x') is the independent variable so that leaves only options 1 and 3 as the answer
is the slope equal to 0.6 or 1.8?
I used the slope formula with the following points: (1,2) and (5,9)
(9-2) / (5-1) = 7/4 = 1.75, or 1.8
You have to do 91/13 which is 7 which means that each hen lays 7 eggs per week so the unit rate is 7
The total cost before books are printed is $1200 (the constant).
The change to the total cost is the x, which is a variable, and can change depending on the amount of books printed.
hope this helps
Answer:
x = 4√5
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Trigonometry</u>
- Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use Pythagorean Theorem.
a = 19
b = x
c = 21
<u>Step 2: Find </u><em><u>x</u></em>
- Substitute: 19² + x² = 21²
- Isolate <em>x</em> term: x² = 21² - 19²
- Evaluate: x² = 441 - 361
- Subtract: x² = 80
- Isolate <em>x</em>: x = √80
- Simplify: x = 4√5
And we have our final answer!
Y=mx+b
y= -2x+8
Rearranging gives you the answer of
2x +y - 8 = 0
