X=67/2
y=-67/3
x and y intercepts
A) One solution: 5x +2y = 0 . . . . (any line with a different slope)
b) Two solutions: not possible
c) No solutions: 5x -2y = 0 . . . . (any different line with the same slope)
d) Infinitely many solutions: 10x -4y = 6 . . . . (any other equation for the same line)
Answer:
Ur mom lol she gave birth to a kid who knows nothin
Step-by-step explanation:
Answer:
6 times
Step-by-step explanation:
28claps =12seconds
? = 0.5minutes
60seconds=1minute
? =0.5 minutes
(cross multiply)
60*0.5/1 = ?
?=30seconds
28claps = 12secs
? =30secs
28*30/12 =?
?=70claps
substitution and elimination means that you need to use one equation and substitute it in place of some variable in the other equation.
Consider the above two equations.
Take equation 1, which is 4x-2y=22 => x=(22+2y)/4
substitute the x value gained above in equation 2.
so, 2((22+2y)/4)+4y=6
22+2y+8y=12 => 10y = -10 => y= -1.
Substitute y= -1 in x value obtained in the beginning.
So, x= (22 - 2)/4 => 5.
There fore, x= 5 and y= -1
Hope it helps.
