I can't give you all the answers, because that would be cheating. How ever, I will give you the first 5 answers.
Move the decimal so there is one digit to the left of the decimal point. The places the decimal moved would be the exponent for 10.
- 3.456*10^2
- 8.89*10^-3
- 2.35*10^5
- 2.35*10^-2
- 3.015⋅0
Ya i think that it would bee
Step-by-step explanation:
well,
(y - 7)² = (y - 7)(y - 7)
remember how to multiply 2 expressions ?
you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).
so, when we do the multiplication, we get
(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =
= y² - 14y + 49
and that is clearly different to y² - 49
FYI
y² - 49 is the result of
(y - 7)(y + 7)
because
y×y + 7×y - 7×y + (-7)(7) = y² - 49
The y-in is -6
The x- in is -1 and -6
The vertex is (-3.5,-6.25)
The axis is -3.5
