In general, the functions are of the form
![y = f(x) = mx +b](https://tex.z-dn.net/?f=y%20%3D%20f%28x%29%20%3D%20mx%20%20%2Bb)
The linear functions are
![f(x) = 6x + 4\\f(x) = 5x -2](https://tex.z-dn.net/?f=f%28x%29%20%3D%206x%20%2B%204%5C%5Cf%28x%29%20%3D%205x%20-2)
Let
.
A. False: the lines are parallel if
but this does not happen.
B. False. The lines are perpendicular if
and clearly this does not happen.
C. ![6x + 4 = 5x - 2\\x = -6\\6(-6) + 4 = -32 = 5(-6) -2](https://tex.z-dn.net/?f=6x%20%2B%204%20%3D%205x%20-%202%5C%5Cx%20%3D%20-6%5C%5C6%28-6%29%20%2B%204%20%3D%20-32%20%3D%205%28-6%29%20-2)
Then C is true.
D. False. The lines are not the same.
Answer:
6
Step-by-step explanation:
After 10 hours he has graded 10*7 papers which is 70
76-70 = 6
L = 2w + 4 , l + w = 80
solve using subsitiution.
(2w + 4) + w = 80
simplify / combine common
3w + 4 = 80
subtract 4 from both sides
3w = 76
divide by 3
w = 25 1/3 in
80 - 25 1/3 = 54 2/3
is it true that 54 and 2/3 inches is 4 inches more than two times 25 1/3? Yes.
Length = 54 and 2/3 inches
W = 25 and 1/3 inches
hope this helps ;D
They both have the same variable(s) and equal the same thing
Answer:
A
Step-by-step explanation:
A. The constants a, b, and c must be real numbers with a not ever equal to zero.
