Which expression has an equivalent value to x2 + 9x + 8 for all values of x?
exis [7]
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:

\boxed{x^2 + 9x + 8 }

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: \boxed{\boxed{\bf{ (x + 1)(x + 8) }}}

The expression 8x2 − 64x + 720 is used to approximate a small town's population in thousands from 1998 to 2018, where x represen
mezya [45]

Answer:

8(x-4)^{2}+592

Step-by-step explanation:

we have

The expression  8x^{2} -64x+720

This is a vertical parabola open upward

The vertex is a minimum

Convert the expression in vertex form

Factor the leading coefficient

8(x^{2} -8x)+720

Complete the square

8(x^{2} -8x+16)+720-128

8(x^{2} -8x+16)+592

Rewrite as perfect squares

8(x-4)^{2}+592

The vertex is the point (4,592)

That means -----> 4 years since 1998 the population has a minimum

A group of 3 friends order a combo meal which includes two slices of pizza and a drink. Each drink is priced at $2.50. If the co
Verizon [17]

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 = \frac{29}{2} = $ 14.5

Hence The cost of each slice of pizza is $ 14.5   Answer

-8x + 14 = -2(4x - 7) what is the value of x
Vikentia [17]

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
