First deal withe the numerator 4 x^2
square root of 4 is 2 and square root of x^2 = x
so square root of 4x^2 is 2x
as for the 3y we can write it as √(3y)
so answer is 2x / √(3y)
Answer:x + 12y = 4
9x + y = 10
-9x + y = -7
Step-by-step explanation:idk for sure tho man
Answer: C... {y|y ≥ -1}
Step-by-step explanation:
f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.
in vertex form (h, k) = (-1, -11)
This meaning the range ={y|y ≥ -11}
Answer:
The linear function is
Step-by-step explanation:
A linear function has the following format:
In which m is the slope and b is the y-intercept(the value of y when x = 0).
In the table, we have that when x = 0, y = 2
This means that . So
Finding the slope:
We take two points, and the slope is given by the change in y divided by the change in x.
Points (0,2) and (1,-1)
Change in y: -1 - 2 = -3
Change in x: 1 - 0 = 1
Slope:
So
Step-by-step explanation:
The extreme value is −4. To see whether it is a maximum or aminimum, in this case we can simply look at the graph. f(x) is a parabola, and we can see that the turning point is a minimum. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).
