X−10y=12 10x+10y=10 Addition Elimination
2 answers:
Answer:
x = 2
y == -1
Step-by-step explanation:
<h2>Solving linear equations by elimination method:</h2>x - 10y = 12 ----------------(I)
10x + 10y = 10 --------------(II)
We can find the value of 'x' by eliminating 'y'. To eliminate 'y', add equations (I) & (II)
(I) x - 10y = 12
(II) <u> 10x + 10y = 10</u> {Now add the equations}
11x = 22
x = 22 /11
Now, Plugin x = 2 in equation (1)
10*2 + 10y = 10
20 + 10y = 10
10y = 10 - 20
10y = -10
y = -10/10

Answer:
The Given situation is In 2005, the shabelle river in Somalia rose an estimated 5.25 inches every hour for 15 hours.
Increase in water level is represented by the function,f(x)=5.25 x.
or replacing f(x) by y we get ,y= 5.25 x
This is equation of straight line passing through the origin.
As x is number of hours , so x> 0,(0,∞] Which is it's domain.
As x> 0, so Range is those values of y for which x is defined.
,So Range is y>0 i.e (0,∞}
As the function has no breaking point , that is when you plot the graph on coordinate axis there is no breaking point.So , it is everywhere continuous i. e for all values of x.
