Answer:
Step-by-step
sum of the adjacent angles of parallelogram is supplementary.
Therefore,
Q + R = 180°
4y+7 + 10y-37 = 180°
14y - 30° = 180°
14y = 210°
y = 210°/14
y = 15°
Could not found X in the question.
Option I: 10 candy bars for $6.75
<span>6.75/10 = 0.68 </span>
<span>Option II: 12 candy bars for $7.25 </span>
<span>7.25 / 12 = 0.60 </span>
Answer:
See explanation
Step-by-step explanation:
You are given the function 
The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:

The table is

The inverse function
has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}
Answer:

Step-by-step explanation:
Tetrahedron:
4 faces, 6 edges, 4 vertices
Cube:
6 faces, 12 edges, 8 vertices
Octahedron:
8 faces, 12 edges, 6 vertices
you can also use the v - e + f = 2 to check
Answer:
y= 4 , x= -1
Step-by-step explanation:
3x-9y= -39
-3x-7y= -25
-16y= -64
y= -64/-16
y= 4
substitute y into any equation
3x -9(4) = -39
3x-36= -39
3x= -39+36
3x= -3
x= -3/3
x= -1
