Answer:
-2
Step-by-step explanation:
n(-2) = -1 - (-2) + 4 = -1 + 2 + 4 = -1 + 6 = 5
( - 1 , 6 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [6] is +. So, result is 5)
n(0) = -1 - 0 + 4 = -1 + 4 = 3
n(5) = - 1 - 5 + 4 = -6 + 4 = -2
( -6 , 4 one has +sign and other -sign. So different sign mean, we have subtract and the sign of the result will be the bigger number's sign. Here bigger number [-6] is -. So, result is -2)
Answer:
B
Step-by-step explanation:
Given arc FG then the central angle is the angle at the centre subtended by FG , that is
central angle = ∠ FQG
Answer:
Step-by-step explanation:
- - 9x - 5y = -18
- 4x + 5y = 33
<u>Add up the two equations:</u>
- -9x - 5y + 4x + 5y = -18 + 33
- -5x = 15
- x = -3
<u>Finding y:</u>
- -9*(-3) - 5y = -18
- 27 - 5y = -18
- 5y = 27+18
- 5y = 45
- y = 9
Answer is: (-3, 9)
We can set up a system of equations to solve this.
120b + 90d = 270
60b + 110d = 265
To cancel out b, first make the b terms equal.
60b · 2 + 110d · 2 = 265 · 2
120b + 220d = 530
Now subtract the equations.
120b + 90d = 270
-120b + 220d = 530
---------------------------
-130d = -260
Solve for d.
-130d/-130 = -260/-130
d = 2
Now put the value of d in one of the equations.
60b + 110d = 265
60b + 110 · 2 = 265
60b + 220 = 265
60b + 220 - 220 = 265 - 220
60b = 45
60b/60 = 45/60
b = 0.75
Each candy bar sells for $0.75

We are given with the following vertices:
A (0,0)
B (-1,1)
C(6,1)
D (2.0)
Next is to plot the vertices in the Cartesian plane so that we can identify the figure. See attached image.
The identified shape is a "Parallelogram".
