Find the x-intercepts for the parabola defined
Ulleksa [173]

Answer:

(- 2, 0 ), (1, 0 )

Step-by-step explanation:

Given

y = 2x² + 2x - 4

To find the x- intercepts let y = 0, that is

2x² + 2x - 4 = 0 ← divide through by 2

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Thus x- intercepts are (- 2, 0) and (1, 0)

Name the property shown by each statement and which is associative or commutation or simply
NeX [460]

Answer:

The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like!.

The Commutative property states that order does not matter. Multiplication and addition are commutative.

A club decides to sell t-shirts for 15 as a fundraiser. It costs 20 plus 9 per t-shirt to make the t-shirts. Write and solve an
zepelin [54]

The club needs to make and sell 29 t-shirts in order to profit at least 150.

<em><u>Explanation</u></em>

Suppose , the number of t-shirts the club needs to make and sell is x

Selling price of each t-shirt is 15, so the total selling price of x t-shirts = 15x

It costs 20 plus 9 per t-shirt to make the t-shirts. So, the total making cost of x t-shirts = 20+9x

Now for getting profit at least 150 , the equation will be.....

15x-(20+9x)= 150\\ \\ 15x-20-9x=150\\ \\ 6x-20=150\\ \\ 6x=150+20=170\\ \\ x= \frac{170}{6}=28.333....

It means the value of x should be at least 28.333...

<em>As here x is the number of t-shirts and it can't be in decimal , so </em><em>the minimum value of x will be 29.</em>
