Answer:
the three boxes should be filled with
2 8 -12
respectively
Step-by-step explanation:
The general equation of the parabola in this problem is
y = a(x-h)^2 + k
vertex is at (-2, -20), => k=-20, h = 2
so the equation is
y = a(x+2)^2 - 20
To have y-intercept = -12, we set x = 0
-12 = a(0+2)^2 - 20
a(2^2) = 8
a = 2
therefore the equation of the parabola is
y = 2 (x+2)^2 -20 = 2x^2 + 8x - 12
the three boxes should be filled with
2 8 -12
respectively
Commutative property of multiplication
The measures of arcs are double of the measures of the angles
so 80° => 160°
90° => 180°
96° => 192°
94° => 188°
Answer:
The graph is included below as an attachment.
The slope is the ratio of the change in the cost to the change of the amount of deli meat. The magnitude means that there is a change of 3.5 units in the cost per each pound of change of deli meat.
Step-by-step explanation:
The following linear equation represents the cost (), measured in dollars, as a function of the amount of deli meat (), measured in pounds:

The graph is included below as an attachment.
The slope is the ratio of the change in the cost to the change of the amount of deli meat. The magnitude means that there is a change of 3.5 units in the cost per each pound of change of deli meat.
Answer:
(10, 5 )
Step-by-step explanation:
To determine which points lie on the graph or not.
Substitute the x- coordinate of the point into the equation and if the value agrees with the y- coordinate of the point then the point is on the graph.
(2, 7 )
y = 2 + 5 = 7 ← True thus point is on the graph
(6, 11 )
y = 6 + 5 = 11 ← True thus point is on the graph
(220, 225 )
y = 220 + 5 = 225 ← True thus point is on the graph
(10, 5 )
y = 10 + 5 = 15 ≠ 5 ← Point is not on the graph
