What grade is that?................
Sense you do not have any options, this may be quite harder, But, I believe I got this. So, by looking at the following, it would look like the expression below:

We cant not use the numbers that are above to would give us 8. 2+9 would not equal 8 which would then show us that your answer may be the following:
Your answer:
Answer:

Step-by-step explanation:
we have
The expression 
This is a vertical parabola open upward
The vertex is a minimum
Convert the expression in vertex form
Factor the leading coefficient

Complete the square


Rewrite as perfect squares

The vertex is the point (4,592)
That means -----> 4 years since 1998 the population has a minimum
Answer:
The cost of each slice of pizza is $ 14.5
Step-by-step explanation:
Given as :
The combined total of 2 slices and 1 drink cost = $ 31.50
The price of each drink = $ 2.50
Let The number of slices = S
The number of drink = D
According to question
2 × S + 1 × D = $ 31.50
∵ 1 drink cost $ 2.50
So, 2 × S + 1 × D = $ 31.50
Or, 2 × S + 1 × $ 2.50 = $ 31.50
Or, 2 × S = $ 31.50 - $ 2.50
Or , 2 × S = $ 29
∴ S =
= $ 14.5
Hence The cost of each slice of pizza is $ 14.5 Answer
Answer:
Step-by-step explanation:
-8x + 14 = -2(4x - 7)
use the distributive property to get rid of the parentheses (-2 x 4x and -2 x -7) (negative times negative equals positive)
-8x + 14 = -4x + 14
subtract 14 on both sides to cancel out 14
-8x is not equal to -4x
although this may seem like a weird answer, if x is the same variable (pretend it's one) 1 multiplied with -8 will not equal 1 multiplied with -4
