Answer:
A and B
Step-by-step explanation:
Given
Required
Determine the appropriate combination
First, we need to determine the factors of 28 and 21
Next, is to bring out the similar traits in both factors
Represent both in terms of bag, we have:
1 bag of 28 nuts
7 bags of 4 nuts
1 bag of 21 dried fruits
7 bags of 3 dried fruits
This gives:
1 bag of 28 nuts and 1 bag of 21 dried fruits
7 bags of 4 nuts and 7 bags of 3 dried fruits
Hence:
<em>Option A and B are correct</em>

- y=2x²+6x+1
- y=-4x²+1
Make the equations equal and solve for x
- 2x²+6x+1=-4x²+1
- 6x²+6x=0
- 6x(x+1)=0
- 6x=0 or x+1=0
- x=0 or x=-1
For x=0
- y=-4(0)+1=1
For x=-1
- y=-4(1)+1=-3
The solutions are
- (0,1) and (-1,-3)
Graph attached
the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
