Answer:
OPTION 1
Step-by-step explanation:
You just basically plug in x and y values in all the equations and check if you get the same answer each time.
Option 1 is correct because when you plug in let's say the first coordinates,10 and 4 it does give you 6 which is right.
Or you can test it the other way, just plugging in x values and see if you get the right y value for it shown above in the table.
Hope this helps!
Answer:
Step-by-step explanation:
The temperature at a given altitude is
y = 36 - 3x
The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.
y = 36 - 3*0
y = 36
So at the surface of the planet is 36 degrees C.
======================
Effectively it is the slope of the equation which is - 3
So ever km going up will mean a loss of 3 degrees. I think they want you to write -3
Hey there!!
Given:
... A=3B+7C
Subtracting 7C on both sides:
... A-7C=3B
Dividing by B on both sides:
... (A-7C)/3=B

<u>Given:</u>
Zoe gets paid a 1% commission for every sale she makes in addition to base pay.
She sold $8,000 worth of computers on a day and made $140 that day.
<u>To find:</u>
A function P(x) representing total pay on a day where she sells x dollars worth of computers.
<u>Solution:</u>
To determine the function P(x) we need to determine how much Zoe's base pay per day is.
One day, she sold $8,000 worth of computers and made $140 that day.
She gets a commission of 1% for $8,000.
1% of $8,000
So she got paid $140 out of which $80 was a commission.
So her base pay
So Zoe's base pay is $60 a day.
P(x) is the sum of her base pay and 1% of the amount of computer sales she makes ($x).
So , where x is the computer sales she makes in dollars. P(x) is represented in dollars.
