Which equation describes relationship between X and Y in the table?
2 answers:
Answer:
D
Step-by-step explanation:
Based off the answers, we are supposed to find the slope. You can tell since the only thing differing between the answers are the slope.
First you take two points and then plug them into the following equation to solve for slope.
Let's use the points (0, 0) and (4, -1).

Step-by-step explanation:
Find the value of x in each of the following
1) x-1+5√x-1+3=0
5√x-1 = -x -2
Square both sides
25(x-1) = (-x-2)^2
25(x-1) = x^2+4x + 4
25x-25 = x^2+4x + 4
x^2 +4x + 4 - 25x + 25 = 0
x^2 - 21x + 29 = 0
x = 21±√21²-4(29)/2
x = 21±√441-116/2
x = 21±√325/2
x = 21±18.03/2
x = 21+18.03/2 and 21-18.03/2
x = 19.515 and 1.485
4) x^4-64=0
x^4 = 64
x = 2.83
