In order to add these fractions we have to make a common denominator.
1/5 can turn into 2/10 Its the same thing. And its easier to solve with.
now lets multiply.
× 
Now we add across
2 + 1 = 3
------------
10 + 10 = 10 ( When adding fractions like these the denominator stays the same)
So your answer is...
Good Luck! :)
Try this solution:
1. if to transform the given equation into the standard form:
x²+y²-4x+6y-3=0;
(x²-4x+4)+(y²+6y+9)-16=0;
(x-2)²+(y+3)²=4²
2. Using the standard form it is possible to find the coordinates of the centre of given circle: x=2; y= -3
answer: b) - (2;-3)
Answer:
The correct answer is the last option (d.)
Step-by-step explanation
There are 8 different bathing suits,
5 pairs of shorts,
3 cover-ups,
and 2 different flip flops.
So the number of options Emily can pick is 8 * 5 * 3 * 2 = 240.
Since no example is being given, let's take for instance 2 functions, one quadratic & the second linear:
y₁=ax²+bx+c & the second y₂=mx+b
The solution of those function is the coordinates (x,y) where both meet at a point . In this case (& in all other cases) you have to state that y₁=y₂
ax²+bx+c = mx + b & solve
example
y₁= x²+3x-1 & y₂=x-2
x²+3x-1 = x-2==>x²+3x-1-x+2 = x²+2x+1
Find the root of x²+2x+1 & you will find x'=x" -1
We have found the value of x= - 1, to find y, just plug into any of the equation x by its value & you will find y=-3
So the solution of this system of equation is at their pint(s) of intersection, that is (-1,-3)
