X= -1/4 I honestly have no idea but i hope this helps and if you get it wrong let me know and then we can see if other answers are right.
Step-by-step explanation:
Subtract equation ( ii ) from equation ( i ) :
Remember that the sign of each term of the second expression changes i.e equation ( i ) now becomes -4x -3y = -20

Answer: a. (2.5, 300°) and (-2.5, 120°)
b. (4, 270°) and (-4, 90°)
<u>Step-by-step explanation:</u>
Polar coordinates are written as (r, θ) where
- r is the radius
- θ is the angle
In the first graph, the radius is 2.5 and the angle is 300° --> (2.5, 300°)
You can also list the radius as -2.5 at angle 120° --> (-2.5, 120°)
↓
(300 - 180)
In the second graph, the radius is 4 and the angle is 270° --> (4, 270°)
You can also list the radius as -4 at angle 90° --> (-4, 90°)
↓
(270 - 180)
Answer:
5.76 ounces of fruit
Step-by-step explanation:
7.63 + 5.26 = 12.89
12.89 - 1.37 = 11.52
11.52 / 2 = 5.76
Therefore, 5.76 would be your answer.
