Answer:
Step-by-step explanation:
9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:
10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:
11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:
Solving for 'x' we get:
12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:
Answer:
D. It would be less steep.
Step-by-step explanation:
→When the absolute value of the number in front of x is greater than 1, the function on the graph narrows. When the absolute value of the number in front of x is less than 1, the function on the graph widens.
<u>In this case, the number is less than 1, making it grow wider. And as a result of it growing wider, it also becomes less steep.</u>
Y=-x+2
2y=x-8
these two lines both go through the point (4,-2)
solve: substitute the y in the second equation with (-x+2):
2(-x+2)=x-8
-2x+4=x-8
add 2x on both sides:
4=3x-8
add 8 on both sides: 12=3x
divide by 3 on both sides: x=4.
find y: y=-x+2=-4+2=-2
the solution is (4,-2)
Answer:
count them: 12
Step-by-step explanation:
All of the edges are shown in the figure. 9 are visible, and 3 are hidden, as indicated by their being a lighter gray (dotted). You can answer this question by counting the edges.
The total number of edges that a cuboid has is 12.
