Which type of compound inequality is |y−3|−4≤−3?
a.) disjunction
b.) intersection
c.) hole
d.) union
Answers
Answer:
b.) intersection
Step-by-step explanation:
The given inequality can be rearranged so that you can see the solution space is one continuous interval.
__
It is described by the intersection of two inequalities.
|y -3| -4 ≤ -3 . . . . . . given
|y -3| ≤ 1 . . . . . . . . add 4
-1 ≤ y -3 ≤ 1 . . . . . "unfolded", the intersection of two inequalities
2 ≤ y ≤ 4 . . . . . . . add 3
This means 2 ≤ y and y ≤ 4, the intersection of the two inequalities.
_____
Additional comment
If the inequality were of the form ...
|y -3| ≥ 1
then it would "unfold" to ...
-1 ≥ y -3 or y -3 ≥ 1
and the solution intervals would be disjoint. The solution would be the union of the solution intervals of the individual inequalities.
Answer:
intersection is right

Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
Answers
Answer:
The results do not in anyway represent the population reason been that the sample does not represent professors from different areas but only tend to represent 50 professors from his hometown university

Based on the information given the results of his survey does not in anyway represent the entire response from the population of college professors reason been the surveys carriedout by him was only for 50 professors from the university in his hometown and not professors from different areas which means that the sample or survey about the amount of money that average college professor make collected by him was not accurate.

Solve using substitution.
4x - 5y = 1
x = -6
Answers
-24-5y=1
Minus 1 on both sides
-25-5y=0
Plus 5y
-25=5y
Divide by 5 on both sides
y=-5
Answer:
y = -5
Step-by-step explanation:
To solve by using substitution, first substitute x for -6 in the equation 4x-5y=1
4(-6)-5y=1 start by simplifying this problem
-24-5y=1 now you can solve for y, add 24 on both sides
-5y=25 now divide -5 on both sides
y= -5
