Answer:
21 Snowmen
Step-by-step explanation:
The perimeter of your yard is 25ft + 28ft + 25ft + 28ft = 106ft
Each snowman is 5ft across, so divide 106ft by 5ft.
106ft / 5ft = 21 with a remainder of 1ft
2160 - 180 - 432 = 612
Each parallelogram is 3 square inches
divide by 3
612/3 = 264 parallelograms to complete the quilt.
Angle 12 and Angle 10 are vertical angles.
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
Answer:
Option C
Step-by-step explanation:
We can easily see the solution by realizing that the quadratic function
y = x^2 + 2 has a discontinuity at x =1 (white dot at the graph)
So, the solution must have
y = x^2 + 2 , x < 1
And the only option in which this applies is Option C.
