Step-by-step explanation:
a^2+b^2 = c^2
C is the biggest number, so put in all the numbers in the equation then if it's equal then it's a right triangle.
example: 6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
this one is a right angle because the two sides is equal to the hypotenuse(largest number).
Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
<u>Answer:</u>
1/9 > -4
because -4 is a negative no less than 0. whereas 1/9 is a positive no greater than 0.
So negative no can't be greater than positive no.
