Answer:
option B 5
option D -6
Step-by-step explanation:
Given in the question an inequality
x² > 16
Step 1
Take square root on both sides of inequality
√x² > ±√16
x < -√16 or x > √16
x < -4 or x > 4
Step 2
-4 > x > 4
x = 5 x > 4 accepted
x = -6 x < -4 accepted
Step 3
x = 4 rejected
x = -1 rejected
Answer:
21. B. Graph Z
23. A. neither function nor relation
24. D. relation only
Step-by-step explanation:
21. Graph Z is the only graph which does not pass the vertical line test
23. The graph does not pass the vertical line test, AND it is not merely given x and y points like a relation. It is graphed as a squiggly line with no given x and y points, therefore you could not make a relation from it either.
24. There is an x value of -4 twice, meaning the set does not pass the vertical line test, HOWEVER, it is a given collection of x and y values, making it a relation.
I would appreciate brainliest, have an amazing day
The earth is approximately 93,000,000 miles from the sun. If it were 10x further, it would be 930,000,000
That would place it closest to Saturn which is about 890,000,00 miles away from the sun.
We just take the square root of 16384.
√16384 = 128
128^2 = 16384
Best of Luck!
Answer:
, 
, 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Find the value of the constant of proportionality k
take any ordered pair from the data
For x=25, y=160
substitute the values of x and y
simplify
The linear equation is equal to
or
