Step-by-step explanation:
Answer:
- 1. Adjacent, 2. Vertical, 3. Neither
Step-by-step explanation:
1.
- The first pair is adjacent as they have common side.
2.
- The second pair is vertical as opposite angles of the crossed lines.
3.
- The third pair has no relationship with each other, so neither is the answer.
Answer:
Option A. 
Step-by-step explanation:
Let
d -----> the number of days
C(d) -----> the total cost
we know that
The linear equation in slope intercept form is

where
m is the rate or slope of the linear function
b is the y-coordinate of the y-intercept
In this problem we have that

The slope of the linear equation is equal to the charge of $25 per day to board dogs
so

The y-intercept is the value of y when the value of x is equal to zero
In this problem the C-intercept is the total cost when the number of days (d) is equal to zero
The C-intercept is equal to the cost of the bath $12
so

substitute the values

Answer:
5/9 or 0.555
Step-by-step explanation:
(2/3)^2 + (1/3)^2
Multiply 2/3 twice and 1/3 twice, and then add both
4/9 + 1/9
5/9 or 0.5555
-6+-7 is the correct answer
