2x-4y=14
X=2y-2
2x-4y=14
x-2y=-2
x-2y=12
x-y=-6
You will have it in 15 days. Both 5 and 3 have a least common multiple of 15.
Answer:
15.12 ÷ 12 = 1.26 per burger
y = mx +b
y = -2x +0
the y intercept is 0
so one point is (0,0)
the slope is -2
we go down 2 to the right 1 (1,-2)
we now have 2 points
2 points make a line
Answer:
Plot and connect (5,4), (3,0) and (7,0).
Step-by-step explanation:
This is in factored form and can be graphed directly from the equation. The equation shows the x-intercepts.
The x-intercepts are found by solving for x using the zero product rule.
(x-3)=0 so x = 3
(x-7) = 0 so x = 7
The intercepts are (3,0) and (7,0). Plot the points. The vertex will occur halfway between these points. 7-3 / 2 = 4/2 = 2. This means the axis of symmetry is at x = 5 and this is the x-coordinate of the vertex too.
Substitute x = 5 into the equation and solve for y.
-(5-3)(5-7) = -(2)(-2) = 4
The vertex is (5,4). Plot it and connect the points.
