Mice21 [21]
Given that the equation looks like: (8^1)0

This means that our first step is to do what is in Parenthesis. 8^1 is = to 0

This means our equation now looks like:
(8)0

When you multiply anything by zero, it becomes zero.

This means your answer should be A.0

Which is the graph of the function f(x) = 1/2x2 + 2x - 6?
Morgarella [4.7K]

Answer:

1/2 x^2 + 2x - 6 = 0

(1/2 x - 1)(x + 6) = 0

zeroes are 2 and -6

so the graph intersects x axis at -6 and 2

The only one to do that is diagram A

Jessica and Josh are selling Entertainment Books to raise money for the art room at their school. One book sells for $15. Jessic
melisa1 [442]
<h2><u>Answer</u><u>:</u><u>-</u></h2>

Jessica sells = 240 books,

Josh sells = 16 books.

<h3>Given:-</h3>

The price of one book is = $15

Jessica sold 15 times more books than Josh.

In total, they have sold 256 books.

<h3>Solution:-</h3>

We can easily find the answer using variables.

Let,

Josh sold a total of x books whereas Jessica sold a total number of 15x books.

together they sold 16x books.

So we can form the equation

16x= 256

by solving this equation we will get x=16

So, Josh sold 16 books and Jessica sold 16×15=240 books in total.

1) Solve the following system of equations algebraically. Give your solution as two
Bad White [126]

For this case we have the following system of equations:

y = x ^ 2 + 7x + 12\\y = 2x + 8

Equating both equations we have:

x ^ 2 + 7x + 12 = 2x + 8\\x ^ 2 + 7x-2x + 12-8 = 0\\x ^ 2 + 5x + 4 = 0

We must find the solutions, for this we factor. We look for two numbers that, when multiplied, result in 4 and when added, result in 5. These numbers are 4 and 1:

4 + 1 = 5\\4 * 1 = 4

Then, the factorized equation is of the form:

(x + 4) (x + 1) = 0

Thus, the solutions are:

x_ {1} = - 4\\x_ {2} = - 1

We look for solutions for the variable "y":

y_ {1} = 2 (-4) + 8 = -8 + 8 = 0\\y_ {2} = 2 (-1) + 8 = -2 + 8 = 6

Thus, the system solutions are given by:(x_ {1}, y_ {1}): (- 4,0)\\(x_ {2}, y_ {2}): (- 1,6)

ANswer:

(x_ {1}, y_ {1}): (- 4,0)\\(x_ {2}, y_ {2}): (- 1,6)
