a
b
c
d
Step-by-step explanation:
Well lets look,
a)
If both slopes are different and have different y intercepts they have 1 solution.
So a has 1 solution
b)
Both slopes are different with different y intercepts.
1 solution
c)
Both slopes are different with different y intercepts
1 solution
d)
Different slopes different y intercepts
1 solution.
For proof look at the images below.

The answer is d.
Remember open circle means that it cannot be equal to that value while closed circle means that it can be.
Answer:
B
Step-by-step explanation:
Solution :
It says multiply 8 by 12 and then add 9
reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .
Let us first write multiplying 8 and 12 which makes it 8 x 12
the result is being add to 12 so we place 8x12 in parenthesis then add 12
which , makes it : ( 8x12) + 9
this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .
we can write it without parenthesis like : 8x12 +9
Answer is third option .
No, Alex is wrong. The correct expanded form would be 100+60+5+.03+.008
