Answer:</h2>
The following which is not a requirement of a standard form of equation Ax+By=C is:
b) B ≥ 0
<h2>
Step-by-step explanation:</h2>
We know that the standard equation of a line is given by:
where A,B and C are integers and A is taken to be a non-negative integer i.e. (A≥0) also the greatest common factor of A,B and C is: 1.
Also A and B can't be both zero.
Hence, the correct option is:
Option: b
Answer:
Step-by-step explanation:
<u>20% of juice has:</u>
- 10*0.2 = 2 cups of extract
<u>If x cups of juice added we'll have:</u>
- 2 + x*0.15 = 0.17(10 + x)
- 2 + 0.15x = 1.7 + 0.17x
- 0.17x - 0.15x = 2 - 1.7
- 0.02x = 0.3
- x = 0.3/0.02
- x = 15
Answer:
B
Step-by-step explanation: let me know if this is wrong
34 + 0 + 18 + 26
= (34 + 26) + (0 + 18)
= 60 + 18
= 78
Used:
a + b = b + a - commutative property
0 + a = a - identity property
