B
Step-by-step explanation:
The result says y=-x+5 which can be rearrange d to x+y=5
Answer:
<u>Part A: US$ 17</u>
<u>Part B : US$ 102</u>
Step-by-step explanation:
1. Let's check all the information given to us to answer the question correctly:
Dinner bill = US$ 85
Tip to the server = 20% of the bill
2. What’s the tip?
20% = 0.2
Tip to the server = 0.2 * 85
<u>Tip to the server = 17</u>
3. What’s the total of the dinner?
Total of the dinner = Dinner bill + Tip to the server
Total of the dinner = 85 + 17
<u>Total of the dinner = 102</u>
Answer:
b
Step-by-step explanation:
Displacement and distance have different meanings. Displacement is a vector quantity and is the objects overall change in position. Distance is scalar quantity which describes how much ground an object covers during motion.
If they have covered 4 miles from a origin and we don't know the origin but we know that they start there and continue for 4 miles. It will be displacement if they started at a distance and walked a certain distance and the difference from start to finish is 4 miles. Therefore, it must be distance because we don't know the initial position and only that they walked 4 miles.
Mark is right if their starting point is a origin of a coordinate system
Given:
The function is:
To find:
All the possible rational zeros for the given function by using the Rational Zero Theorem.
Solution:
According to the rational root theorem, all the rational roots are of the form 
, where p is a factor of constant term and q is a factor of leading coefficient.
We have,
Here,
Constant term = -2
Leading coefficient = 10
Factors of -2 are ±1, ±2.
Factors of 10 are ±1, ±2, ±5, ±10.
Using the rational root theorem, all the possible rational roots are:
.
Therefore, all the possible rational roots of the given function are 
.
