Answer:
There are many ways to interpret if whether or not a system of equations has solutions or not. Here is one way that is most ideal for most, if not, all equations: using graphs.
- If the graphs of the set of equations do NOT intersect, then there are no solutions (because no x or y value will ever make both equations true)
- If the graphs of the set of equations DO intersect at one point, then ONLY that one point will make both equations true. (One solution)
- If the graphs of the set of equations are identical on the graph, then there are infinite solutions that make both equations true.
Answer:
You scored more than 80 %
Step-by-step explanation:
21/25
We need to change this to a decimal, then to a percent
21/25 *4/4 = 84/100
This is out of 100 so it is 84%
84>80.
You scored more than 80 %
540 - [(180 - 86) + (180 - 76) + (180 - 41) + 9180 - 98) ]
= 540 - (94 + 104 + 139 + 82)
= 540 - 419
= 121
x = 180 - 212
x = 59
The missing fraction is -1/12
Answer:
GCF is 8
16 + 56
= 8(2 + 7)
Step-by-step explanation:
Here, we want to write the greatest common factor of 16 and 56
The greatest common factor is 8
We can use tie rewrite the sum as follows ;
16 + 56 = 8(2 + 7)
