4/8 simplified is 2/4 i think
Answer:
45.5%
Step-by-step explanation:
The increase in population was 45.5%
If f(x)=x^2-8x-20 then
dy/dx=2x-8 and d2y/dx2=2
A) Since acceleration is a constant positive the parabola opens upward.
B) Since acceleration is a constant positive the parabola will have a vertex at an absolute minimum
C) The vertex will occur when dy/dx=0, 2x-8=0, 2x=8, x=4
So the axis of symmetry is the vertical line x=4.
The vertex is y(4)=-36, corresponding to the vertex point (4,-36)
The y-intercept occurs when x=0, y(0)=-20, so the y-intercept is the point (0,-20)
The answer is D.
y = x + 1 = 4 + 1 = 5
y = 1/2x + 3 = 1/2(4) + 3 = 2 + 3 =5
Answer:
B. y + 2 = -2(x - 4)
Step-by-step explanation:
First, find the slope (m) of the line using two points in the line, (3, 0) and (4, -2):
Slope (m) = -2.
Next, substitute (a, b) = (4, -2) and m = -2 into y - b = m(x - a)
Thus:
y - (-2) = -2(x - 4)
y + 2 = -2(x - 4)
