Answer:
Step-by-step explanation:
-6x+5y=0 and −5x+5y=−5
Subtract the second from the first:
-6x+5y=0
<u>5x-5y= 5</u>
-x = 5
x = -5
Well it would equal 12.508 so, 13 I guess.
Just use the order of operations. PEMDAS, parentheses, exponents, multiplication, division, addition and subtraction.
In the first problem 2 + 6*3^2, there are no parentheses, so next would be exponents.
There is an exponent so you do that first.
3^2 = 9
Now we have 2 + 6*9
Multiplication is next and it is in the problem, so we do 6*9 = 54
So now we have 2 + 54 which equals 56.
Answer:
Step-by-step explanation:
first need to find the slope
-4-5=-9
-2-4=-6
=3/2
y-5=3/2(x-4) this is your point slope equation
y-5=3/2x-6
y=3/2x-1 this is your slope intercept equation
-3/2x+y=-1
muliply by -2
3x-2y=2 this is your equation in standard form
Answer:25
Step-by-step explanation:
you just add the sides
