It would be relation B and f (x)
Step-by-step explanation:
for it to be a function X (-8) can only have one outcome, however that isn't the case with A.
and I believe if I'm remembering correctly, one-to-one correspondence is each element of one set is only paired with one element of the other set which isn't true for B, so it should be f (x), though you may want to look it up for yourself to make sure.

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.
Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?
350 m/s
355 m/s
360 m/s
365 m/s
Answers
Answer:360 m/s
Step-by-step explanation:
The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
As we can see in the graph:
When the air temperature is 10°C the speed of sound is around 337m/s
When the air temperature is 20°C the speed of sound is around 344m/s
When the air temperature is 30°C the speed of sound is around 348m/s
When the air temperature is 40°C the speed of sound is around 355m/s
From the above observation, the air temperature increases the speed of the sound increases.
So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.
Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

Answer:
Variables: you are correct
Coefficients: -2
Constant: 3/7
Step-by-step explanation:
Variables are letters used in math so you were correct.
Coefficients are numbers with a variable. So to find the coefficient you would look for a number "connected" to a variable. This would be -2 because it is being subtracted from the first term.
The constant is 3/7 because you could put it on a number line.

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?
Answers
Answer:
$460.20
Step-by-step explanation:
499*15% = 74.85 (total discount price)
499-74.85 = 424.15 (deduct discount from original price)
424.15*8.5% = 36.05275 (total tax from price)
424.15+36.05275 = 460.20275 (add tax to discounted price)

A salesperson’s commission rate is 4%. What is the commission from the sale of $39,000 worth of furnaces? Suppose sales would double. What would be true about the commission?
Answers
Answer:
The earnings will double
Step-by-step explanation:
Step one:
given data
we are told that the sales person's earnings is 4% of the sales made.
given that the sales made is $37,000 worth of furnaces.
Step two:
we want to find 4% of $37,000
=4/100*37000
=0.04*37000
=1480
hence for $37,000 the earning will be $1480.
Now suppose sales is doubled that is 37000*2= 74000
we want to find 4% of $74,000
=4/100*74000
=0.04*74000
=2960.
the earnings is $2960.
So if sales doubles the earnings will double
