Answer:
Equations can have many solutions. The equation of a straight
line, for example, defines all points on the line. Even a simple
equation such as x+y=5 can have a variety of solutions (x=1 when
y=4, x=2 when y=3 and so on)
Answer:
The vertex is at (-3/2, 33/4)
x=-3/2
Step-by-step explanation:
y= -x^2 -3x+6
Factor out a negative from the first two terms
y = -(x^2 +3x) +6
Complete the square
Take 3 /2 and square it (3/2)^2 = 9/4
The - on the outside of the parentheses means we really are subtracting it so we need to add it on the outside
y = -(x^2 + 3x + 9/4) +9/4 +6
= -(x+3/2)^2 + 9/4 +6
Get a common denominator of 4
= -(x+3/2)^2 + 9/4 +6*4/4
y =- (x+3/2)^2 + 9/4 +24/4
y = -(x+3/2)^2 + 33/4
y = a(x-h)^2 +k where (h,k) is the vertex
y = -(x - -3/2)^2 + 33/4
The vertex is at (-3/2, 33/4)
The axis of symmetry is at the x coordinate of the vertex
x=-3/2
x - 2y = -4 solve for y to find slope
x - 2y = -4 - subtract x from both sides
-2y = -x - 4 divide y -2 on both sides
-2 -2
y = 1/2x + 2 (-x/-2 is -1/-2x of 1/2x)
Answer:
most likely 12, because you can take half of the time with double the people.
