Answer:
See below
Step-by-step explanation:
While both are quadratic, second-degree equations, there are a number of differences. y = -2(x+3)^2 - 1 has been flipped over the x-axis (thanks to the negative symbol in front of the 2), stretched by a scale factor of 2, and translated 1 unit down (hence the - 1) and 3 units to the <em>left</em> (full equation for a quadratic equation in vertex form is y = a(x-h)^2 + k. Note the minus sign before the h. This means that the equation was horizontally translated in the opposite direction of what the + or - sign suggests). y=x^2, of course, hasn't had any of these transformations happen to it.
42.38 is the answer i think.
75 is equivalent to 0.75 and
3 devided by 4 is 0.75 i would choose A and B
The answer is c-one 1/2 is the same as 4/8 if you think about it is very easy. Watch since 4/8 is equal to 1/2 that means 3/6,2/4,5/10,12/6 and 32/64 are all equal because all you have to do is divide the denominator in half and that becomes the numerator and it is equivalent to 1/2.
