Answer:
First, add, subtract, multiply, or divide within the parenthesis (if there are parenthesis). Then, you do the exponents. After that, you multiply and divide left to right. Finally, you subtract left the right.
Step-by-step explanation:
Order of Operations is also known as PEMDAS or Parenthesis, Exponents, Multiply, Divide, Add, Subtract. It means if we have an equation that is:
5 + 6 x 2, we do not add first. We multiply first, so we do 6 x 2, which gives us 12. 12 + 5 = 17 and that is your answer.
I hope that this helps! :)
5x+3y=-9
-2x+y=8
The first step is the trickery (and quite frankly, hardest to explain) part. You need to multiply one equation by a number that will create one variable to be the negative version of the other...(Confusing, right? Don't worry, I'll show you)
We are going to solve for X first.
We will multiply the second equation by -3
5x+3y=-9
-3(-2x+y)=(-3)8
Now simplify:
5x+3y= -9
6x-3y= -24
Now combine the two equations (add them together)
11x= -33
Divide by 11
X=-3
Now plug X in to one of the first equations:
5(-3)+3y= -9
-15+3y =-9
3Y= 6
Y= 2
So your final answer is:
x= -3
Y= 2
Hope this helps!
N = x/y because its in the middle
Answer: Negative 1 The slope of parallel lines is the same.
The attachment shows two such lines, given coordinates labeled.
Step-by-step explanation:
Find the slope of the line passing through the given points.
rise/run
Rise is the difference in y-values 7-(-5) = 12
Run is the difference between x-values -5 - 7 = - 12
The Slope is 12/-12 simplify:
slope = -1
