Y = -2x + 4
6x + 3y = 6x + 3(-2x + 4) = 6x - 6x + 12 = 12
⇒ y = -2x + 4 == 6x + 3y = 12 ⇒ invinite solutions: 12
⇒ no solutions -12, -4, 0, 4

Show your work for factoring or quadratic formula:

First, I'd simplify this problem by dividing every term by 2:

x^4 - 4x^3 + 5x^2 - 4x + 4 = 0

Then I'd think of the possible factors of that constant term, 4: They would be plus or minus 1, plus or minus 2, or plus or minus 4.

Let's try x = -4 as a possible root. Setting up and using synthetic division:

____________________
-4 / 1 -4 5 -4 4
-4 32
----------------------------
1 -8 37

This result is not helpful. So, try the possible root +4 instead:
________________
+4 / 1 -4 5 -4 4
   4 0 20 64
   ----------------------------
1 0 5 16 68 4 is not a root because the remainder
(68) is not zero.

Try x = 2:

________________
+2 / 1 -4 5 -4 4
   2 -4 2 -40
     ----------------------------
1 -2 1 -2 0

2 is a root because the remainder is zero.

Continue this process until you've found the other 3 roots.

Hint: Try the possible root x = -2 with the following coefficients:

____________
-2 / 1 -2 1 -2

Stephon is buying some snacks for his siblings at a convenience store. He wants to buy at least 6 items, but he has only $12 in

Irina18 [472]

Answer:

Stephon can buy total 4 chips bag and 2 candy bar

Given as :

The money which Stephon has in his pocket = $ 12

The cost of one chips bag = $ 2.25

The cost of one candy bar = $ 1.50

The total number of items he can buy = 6

So, Let the number of chips bag he can buy = x

∴ The number of candy bar he can buy = 6 - x

Now, according to question

The number of chips bag×The cost of one chips bag + The number of candy bar×The cost of one candy bar = $ 12

Or, x × $ 2.25 + (6-x) × $ 1.50 = $ 12

Or, x × $ 2.25 + 9 - x × $ 1.50 = $ 12

or, x × $ 0.75 = 12 - 9

or, x = = 4

The number of chips bag he can buy = x = 4

And The number of candy bar he can buy = 6 - x = 6 - 4 = 2

Hence Stephon can buy total 4 chips bag and 2 candy bar .
