Answer:
Figure C
Step-by-step explanation:
Figure A represents a ray because it has arrow only on one end.
Figure B is a line segment because it stops on both ends.
Figure C is a line because it has arrow on both ends.
Figure D is an angle, because it is 2 rays joined at a vertex.
Answer:
23d + 45 = 137
Explanation:
Since it is $23 per day, that dollar amount must be associated with a variable that multiples it per day that it is rented. Finally, you need to add the one time $45. This equation can then be used to find how many days it was rented for.
23d + 45 = 137
23d = 92 (Subtract 45 from both sides)
d = 4 (Divide by 23 on both sides)
The rug-cleaning machine was rented for 4 days. You found this using the equation: 23d + 45 = 137
For this case we have that the area of the kite is given by the area of two triangles, the triangles share the same base of 3 + 3 = 6 meters and one has height of 2m and the other height of 4m.
So, the total area is given by:
Thus, the area of the kite is

Answer:
y = (-13/11)x - 5/11
Step-by-step explanation:
Where's the list of equations from which you're to choose?
The line that connects points (-8 ,9) and (3, -4) has the following slope:
9 - (-4)
m = ----------------- = -13/11
-8 - 3
Then the new line with this slope is y = (-13/11)x + c
and because (-8, 9) satisfies this equation, 9 = (-13/11)(-8) + c, and we need to calculate c from this. 9 = 104/11 + c, or
-c = 104/11 - 99/11, or - 5/11
Then the desired equation is y = (-13/11)x - 5/11
