Answer:
x=0
Step-by-step explanation:
substitute y=0
0= -x^2
then swap the sides
-x^2=0 ,
change the signs
x^2=0
set the base equal to 0
x=0
Answer:
The solution is (2, -2)
Step-by-step explanation:
In order to solve this, multiply the second equation by -5 and then add through.
5x - 4y = 18
-5x - 15y = 20
------------------
-19y = 38
y = -2
Now that we have the value of y, we can solve for x.
x + 3y = -4
x + 3(-2) = -4
x - 6 = -4
x = 2
You know you have two hours which will be the whole number. Then you take 36min and put it over 60min (total number of min in an hour) and you simplify by 6 to get 6/10 which can be simplified again to 3/5 so your final mixed number is
2 and 3/5 hours
5 and 96/100 or if you need to simplify 5 and 24/25
Answer:
x can be any number
Step-by-step explanation:
because the two sides are equal x could be any number.
