Answer:
Advantages of representing a function as an equation instead of graph :
- No chance of misinterpretation of the data as making graph involves more data as compared to data needed to represent function as an equation.
- Drawing graphs may be inconvenient in case you need to plot fraction and decimal functions.
Disadvantages of representing a function as an equation instead of graph :
- Visualization is easy in case of graph. Many factors such as maximum, minimum can be easily seen with the help of graph as compared to that of equation of the function.
- With the help of curve of the graph, we can identify the nature of the function much easily than by the equation of the function.
So to find the answer you want to isolate the y. So the first thing you want to do is to move everything to the opposite side of the = sign. You start by adding 10 to both sides.
10+ 5y -10 = -25 +10
5y = -15.
the tens cancel out on the left side and on the right you get left with -15/
Since y is being multiplied by 5 you always want to do the opposite so you divide by 5.
5y/5 = -15/5
y = -3
It's hard to explain but you just have to remember that what you do to one side you must do to the other to keep the equation balanced.
Step-by-step explanation:
(-6x +3y=9 )×4
( 10x+4y)×3
-24x +12y =36
30x+12y= -18
-24x+12y- (30x+12y)= 36-(-18)
-54x = 54
x= -1
by using 10x +4y = -6
apply x= -1
-10+4y= -6
4y= -6 +10
4y=4
y=1
so the answer is x=-1 and y= 1
