Answer:
C
Step-by-step explanation:
If you have a Ti-84 series calculator, press "stat" then "Edit..." and then fill in the data table values for x and y in two lists. Then press "2nd" and "mode" to quit. Now press "stat" again and right arrow over to "calc" and press down until you find "ExpReg" and set the "Xlist" and "Ylist" that you used and you will get C as the answer. Another way to do this is to manually substitute values into all 4 equations, which is boring.
It would be $2.40. 4 or less just ignore 5 or more add 1 more
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation
Answer:
- D. y + 10 = 1/8* (x + 32)
Step-by-step explanation:
Use the given points to work out the equation of the line.
<u>Find the slope:</u>
- m = (- 10 - (-4)) / (- 32 - 16) = - 6 / - 48 = 1/8
<u>Use (-32, - 10) and point- slope form:</u>
- y - (- 10) = 1/8*(x - (-32))
- y + 10 = 1/8* (x + 32)
Correct choice is D
