Answer:
(i) Not true for any cases, (ii) True for some cases, (iii) True for some cases, (iv) True for all cases.
Step-by-step explanation:
Now we proceed to check each statement in terms of concepts of function from Analytical Geometry:
(i) <em>Two lines that have the same y-intercept and the same slope intersect at exactly one point. </em>
False, two lines that have the same y-intercept and the same slope intersect at every point. Both lines are coincident. (Answer: Not true for any cases)
(ii) <em>Two lines that have the same y-intercept intersect at exactly one point. </em>
Conditionally true, two lines that have the same y-intercept intersect at exactly one point if and only if slopes are different. (Answer: True for some cases)
(iii) <em>Two lines that have the same slope do not intersect at any point. </em>
Conditionally true, two lines that have the same slope do not intersect at any point if and only if they share the same y-intercept. (Answer: True for some cases)
(iv) <em>Two lines that have two different slopes intersects at exactly one point.</em>
True, two lines that have two different slopes intersects at exactly one point no matter what y-intercepts they have. (Answer: True for all cases)

Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Part 5) 
Step-by-step explanation:
Part 1) Write as a percent 0.00675
we know that
To write a number as a percent, multiply the number by 100
so

Part 2) Write as a percent 4 3/4
Convert mixed number to an improper fraction

we know that
To write a fraction as a percent, multiply the fraction by 100

Part 3) Write as a percent 2/25
we know that
To write a fraction as a percent, multiply the fraction by 100

Part 4) write as a fraction 335%
we know that

Simplify
Divide by 5 both numerator and denominator

Part 5) Write as a decimal 265%
we know that

-8
2/3(-21/3) + 2/3(-15/3)
-42/9 + -30/9
-72/9 = -8
