Answer:
x=-1
Step-by-step explanation:
1. Remove the parenthesis
-x + 1 = -4x - 2
2. Get x alone
-x + 1 = -4x - 2
+1x +1x
1=-3x - 2
+2 +2
3=-3x -3x/-3= x 3/-3 = -1
x=-1
Parallel graphs have the same slope. perpendicular has opposite reciprocal slopes. These equations have slopes of -2/5 and 25 so they are neither.
As is the case for any polynomial, the domain of this one is (-infinity, +infinity).
To find the range, we need to determine the minimum value that f(x) can have. The coefficients here are a=2, b=6 and c = 2,
The x-coordinate of the vertex is x = -b/(2a), which here is x = -6/4 = -3/2.
Evaluate the function at x = 3/2 to find the y-coordinate of the vertex, which is also the smallest value the function can take on. That happens to be y = -5/2, so the range is [-5/2, infinity).
Answer:
(-1,9)
Step-by-step explanation:
union contains both sets.
1/4 of 4/5
=16/20 divided by 5/20
=16/20*20/5
=320/100
=3.2 or 3 1/5
