Answer:
-61/4
Step-by-step explanation:
-1/2 + x = - 21/4 - 23/4 - 19/4
-1/2 + x = -(21+23+19)/4
x = -63/4 + 1/2
x= -63/4 + 2/4
x = -61/4

Answer:
Step-by-step explanation:
This means that 4/5 repeats itself 3 times.
So,
![\sf = \frac{4}{5} * \frac{4}{5} * \frac{4}{5} \\\\= \frac{64}{125} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20%3D%20%5Cfrac%7B4%7D%7B5%7D%20%2A%20%5Cfrac%7B4%7D%7B5%7D%20%2A%20%5Cfrac%7B4%7D%7B5%7D%20%5C%5C%5C%5C%3D%20%5Cfrac%7B64%7D%7B125%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
Hope this helped!

When they have no solutions, the lines are parlaell, or they have the same slope but different y intercept
example
3x+2y=2 and
3x+2y=4 are paralell
also
y=3x+2 and
y=3x+4 are also parlell, no solutions
infinite solutions are when they are the same line
they have the same slope and y intercept
to find out, simplify
3x+2y=4 and
6x+4y=8 are smae lien
also
y=3x+2 and
2y=6x+4 aer the same line
1 solution is when it is none of the above things
a normal thing, where the slopes are differnet
example
y=2x+2
y=3x+2
