Answer:
<u>Proportional relationship formula:</u>
- y = kx, where k is the constant of proportionality
Use one of the ordered pairs to calculate the value of k
<h3>Company A</h3>
Point (2, 20)
The equation: y = 10h
<h3>Company B</h3>
Point (3, 20)
- 20 = k*3
- k = 20/3
- The equation: y = 20/3h
Company A has greater unit rate as 10 > 20/3
Answer:
B) 10
Step-by-step explanation:
|5-15|
Do what is inside the absolute values signs
5-15
-10
|-10|
Absolute value means always positive so take the positive value of -10
10
Answer:
Range: (-∞, 0]
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:
(-∞, 0] or y ≤ 0
No it is not, the square root is 8.3
