Part A.
Y intercept is the coordinate (0,y), when the function has an x value of 0, it is the y intercept.
In this case:
(0,5) =
y intercept = 5
IT tells about the turtle that it starts at a nest displacement of 5 miles.
Part B
The average rate of change represents the speed .
x1=1 ,y1=27
x2=4 ,y2=93
We have to calculate the slope if the function:
Replace:
Part C.
speed = distance /time
time= distance / speed
time= 225 / 22 = 10.22 hours
The domain will be
0< x ≤ 10.22
Answer:
x=13
y= -9
(13, -9)
Step-by-step explanation:
If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.
Then, we can take that equation and plug it into the bottom one so
3x+4(4-x)=3
Simplify:
3x+16-4x=3
-x=-13
x=13
We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)
So, 13+y=4 which y= -9
For this, we are just going to plug in -9 for every x and then solve the equation:
Now we know that q(-9) is equal to 566.
5x + 10 10
---------- = -------
121 11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18 is your answer
hope this helps
the answer should be A because the sea level has rised
