Answer:
5
Step-by-step explanation:
Subtract 7-2=5.
Domain (x-values)
Range (y-values)
Since they gave you the domain/x-values = -2, 1, 6, you can find the corresponding range/y-values by plugging in these values for "x" in the function:
x = -2
5x + y = 1 Substitute/plug in -2 into "x" to find the value of y
5(-2) + y = 1
-10 + y = 1 Add 10 on both sides to get "y" by itself
y = 11
x = 1
5x + y = 1 Plug in 1 into "x"
5(1) + y = 1 Subtract 5 on both sides
y = -4
x = 6
5x + y = 1
y = -29
Your answer is D
I to help you but describe it in a easier way
I would probably say (0,0) just because (5,0) falls on the x-axis and not on the y-axis and the other are just regular plotting coordinates. (0,0) is the only one that falls on the y-axis although it still falls on the x-axis as well
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8
Hope it helps........
