Answer:The given system of equations has no solution
Explanation:The first given equation is:
2y + 5x = 10
This can be rewritten as:
2y = 10 - 5x ...............> equation I
The second given equation is:
4y + 10x = 2
This can be rewritten as:
2(2y) + 10x = 2 ................> equation II
Substitute with I in II and solve as follows:
2(2y) + 10x = 2
2(10-5x) + 10x = 2
20 - 10x + 10x = 2
20 = 2
Since this is impossible, therefore, the system of equations has no solutions. This means that there is no (x,y) point that would satisfy both equations.
Graphing check:The attached image shows the graphs of the two given functions. We can note that the two lines are parallel each with slope -5/2, which means that they NEVER intersect.
Hence, there is no solution for the given system.
Hope this helps :)
Answer:
i'd say it's "a"
Step-by-step explanation:
cause x= - 1/2, 6/5 so the product of these two is 7/10
Answer:
y = 10x-37
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 10x+b
Substitute the point into the equation
3 = 10*4+b
3 = 40+b
Subtract 40
3-40 = 40+b-40
-37 = b
y = 10x-37
