Answer:

Step 1: Find the prime factorization of the number inside the radical.

Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.

Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.

Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Given the system of equations, what is the solution?5x - 4y = 7x = 5 - 3/2y

nignag [31]

Answer:

(x, y) = (61/23, 36/23)

Step-by-step explanation:

We assume you intend the equations to be ...

5x -4y = 7
x = 5 -3/2y

Then in general form, they are ...

5x -4y -7 = 0

2x +3y -10 = 0

The solution using the "cross multiplication method" is ...

1/(15 +8) = x/(40+21) = y/(-14 +50)

(x, y) = (61/23, 36/23)

_____

<em>Comment on "cross multiplication method"</em>

When the coefficients from the general form equations are written as a 2×4 array with the first and last columns the same ...

$\left\{\begin{array}{cccc}5&-4&-7&5\\2&3&-10&2\end{array}\right\}$

the solution is 1/d1 = x/d2 = y/d3, where d1, d2, d3 are the determinants of successive pairs of columns.

d1 = (5)(3) -(2)(-4)
d2 = (-4)(-10) -(3)(-7)
d3 = (-7)(2) -(-10)(5)

For f(x)=2x+1 and g(x)=x^2-7, find (f+g)(x)

labwork [276]

For this case we have the following functions:

$f (x) = 2x + 1\\g (x) = x ^ 2-7$

We must find the following sum of functions:

(f + g) (x)

By definition we have to:

$(f + g) (x) = f (x) + g (x)\\(f + g) (x) = 2x + 1 + x ^ 2-7\\(f + g) (x) = x ^ 2 + 2x-6$

So, we have to:

$(f + g) (x) = x ^ 2 + 2x-6$

Answer:

$(f + g) (x) = x ^ 2 + 2x-6$
