Answer:
Irrational: √2 = 1.4
Step-by-step explanation:
3.8 because 14+6=20 and .5*20=10 so then you do PEMDAS which means parenthesis, exponents, multiply, divide, add, subtract left to right. So the equation now is 1.8+10-8 so you would do 1.8+10=11.8 and 11.8-8=3.8. In PEMDAS you do the parenthesis first then the exponents and then multiply and divide and then when there is only add and subtract left in the equation you do it left to right.
Answer:
x = 0
Step-by-step explanation:
Given
x² = - 4y ( divide both sides by - 4 )
y = - 
x²
Which is a parabola opening vertically down with it's vertex at (0, 0) and symmetrical about the y- axis
Hence equation of axis of symmetry is x = 0
