Answer:
○ The graph of y = -2x² + 3 opens downward and is shifted up.
Step-by-step explanation:
According to the Quadratic Equation, <em>y = Ax² + Bx + C</em>, <em>C</em><em> </em>acts<em> </em>like a y-intercept, and in this case, since both graphs shift up [because both are positive values], we do not pay attention to those. Now, we come over to our <em>A</em>, which makes a BIG difference because both graphs open in opposite directions [one negative, one positive]. With this being stated, we have our answer.

Answer:
a.
b. 
Step-by-step explanation:
You need to remember that:
1. The word "more" indicates Addition.
2. The "Difference" is the result of a Subtraction.
a. Then, knowing this information, you know that:
- "The difference of
and
" must be expressed as:

- Then, "Three more than the difference of
and
" is:

- "The difference of
and
" can be expressed in this form:

Therefore, "Three more than the difference of
and
is equal to the difference of
and
" is:
b. Solve for "s" in order to find its value:

52,458<52,485
52,485-52,458=27
Answer:
-6/7 < -1/7
because it is more than negative one by seven
