X - 5 = x^2
i) 0 - 5 = -5^2 = 25
ii) 4 - 5 = -1^2 = 1
iii) -4 - 5 = -9^2 = 81
Basiclaly solve for y
8x+4y=16
minus 8x both sides
4y=-8x+16
divide by 4 both sides
y=-2x+4
No, it is an irrational number. It repeats
No, it is an irrational number because it does not terminate/end
The answer is 4.1
If the number is below 5, you round down, if it's 5 or above, you round up.
15x=180
x=12
hope this helps
