Alex Ar [27]

Answer:

x=7

y =-1

Step-by-step explanation:

Given is a system of equations in x and y as

$x+7y=0\\2x-8y =22$

This can be written in matrix form as

Ax = B

$\left[\begin{array}{ccc}1&7\\2&-8\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right] =\left[\begin{array}{ccc}0\\22\end{array}\right]$

Let us find inverse of A

$|A| = -8-14 =-22$

$A^{-1} =\frac{-1}{22} *\left[\begin{array}{ccc}-8&-7\\-2&1\end{array}\right]$

X= A ^(-1) B

x=7, y =-1

If p(x) = x + 3, then what is the value of p(x) + p( - x)?

garik1379 [7]

Answer:

p(x) + p(-x) = 6 is

Step-by-step explanation:

In this question, we are tasked with calculating what p(x) + p(-x) will be

From the question, we know that p(x) = x + 3

Then p(-x) will be p(-x) = -x + 3

Thus p(x) + p(-x) = x + 3 -x + 3

p(x) + p(-x) = 3 + 3 = 6
