Given f(x) = 2x² + 8x - 4 and g(x) = 5x +6, find 3f(x) – 2g(x).

myrzilka [38]

Step-by-step explanation:

When the problem says 3f(x), it means that you are multiplying f(x) by 3. The same goes for 2g(x).

$3(2x^2+8x-4)= 6x^2+24x-12$

$2(5x+6) = 10x+12$

Now, we subtract f(x) from g(x) after being multiplied.

$(6x^2+24x-12)-(10x+12)$

$6x^2+14x-24$

An assistant is in charge of ordering lunch for the monthly office meeting. For the first month, she orders five Falafel wraps,

Andru [333]

Answer:

x (Falafel) = $5.50

y (Turkey BLT) = $7.50

z (Paninis) = $6.00

Step-by-step explanation:

Step 1: Write out systems of equations

5x + 15y + 20z = 260

8x + 18y + 14z = 263

12x + 16y + 12z = 258

There are multiple ways to solve for this systems of equations. I will use an augmented matrix for this:

Top row: [5 15 20 | 260]

Middle row: [8 18 14 | 263}

Bottom row: [12 16 12 | 258]

We find RREF form of the augmented matrix to find our answers:

Top row: [1 0 0 | 11/2]

Middle row: [0 1 0 | 15/2]

Bottom row: [0 0 1 | 6]

And we have our answer!
