HELP PLZ A.
A whale was diving at a rate of 2 meters per second. How long will it take for the whale to
get from the surface of the ocean to an elevation of -12 meters at that rate?
B.
A swimmer dove below the surface of the ocean. After 2 minutes, she was 12 meters below
the surface. At what rate was she diving?
C.
The temperature was -12 degrees Celsius and rose to 2 degrees Celsius. What was the
change in temperature?
D.
The temperature was 2 degrees Celsius and fell to -12 degrees Celsius. What was the
change in temperature?
1.
- 12 + x = 2
2 + x = -12
2.
3.
-2x = -12
2x = -12
4.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )

Answer:

the image is given below

step-by-step explanation:

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
