Answer: Choice A.
(0, b)
==================================================
Explanation:
Pick any random 3 numbers you want for a,b,c.
The points U, W and Z become
- U = (a,0) = (1,0)
- W = (c-a, b) = (3-1, 2) = (2,2)
- Z = (c, 0) = (3, 0)
Or in short,
- U = (1,0)
- W = (2,2)
- Z = (3, 0)
Plot each of those points on the same xy grid.
Next, using a different color, plot each of the answer choices.
- A is at (0,b) = (0, 2)
- B is at (c,b) = (3,2)
- C is at (a,b) = (1,2)
- D is at (b,0) = (2,0)
You should find that point A helps form a parallelogram, while the other answer choices don't lead to a parallelogram.
See the screenshot below. I used GeoGebra to make the diagram. Desmos is another useful tool as well.
Using the process of elimination, we will be able to determine the answer. So, 5x+3y=-10 multiply it by *3 to change the equation into 15x+9y=-30. Then to change 3x+5y=-6 multiply it by *5, to change it into 15x+25y=-30. So now with these two equations 15x+9y=-30 and 15x+25y=-30, use subtraction to get rid of the variable x.
Thus,
15x+9y=-30
-
15x+25y=-30
which will leave you with
-16y=0
thus, y=0
Then, plug y back into the original equation to find x
5x+3(0)=-10
5x=-10
x=-2
Thus the point of intersection is (-2,0)
-2 being the x, and y being 0.
Answer:
the answer is 675.70 or 4,504.33
Step-by-step explanation:
the right answer is that
6.2 you subtract the 0.7 from 6.9 because 0.7 of it is milk chocolate
Answer:
$77.76
Step-by-step explanation:
80x0.10=72
72x 0.08= 5.76
72+5.76 = 77.76
