Answer:

The system has no solution.

Step-by-step explanation:

Write the system as

y - 4x =3

2y - 8x = 3

The 2nd equation can be written as

2(y - 4x)

and the system would be

y - 4x =3

2(y - 4x) = 3

Now, call y -4x = z. Then we would have the system

z = 3

2z = 3

But if z =3 then 2z = 6 and we have a contradiction.

We conclude that the system has no solution.

Evaluate g(p)•h(p) by modeling or by using the distribution property

Nataly [62]

$g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4$

Solution:

Given data:

$g(p)=(p-2)$ and $h(p)=\left(p^{3}+4 p^{2}-2\right)$

To find $g(p) \cdot h(p)$ :

$g(p) \cdot h(p)= (p-2)\cdot \left(p^{3}+4 p^{2}-2\right)$

Distributive property: $a(b+c)=ab + ac$

$= p\left(p^{3}+4 p^{2}-2\right) -2\left(p^{3}+4 p^{2}-2\right)$

$= \left(p^{4}+4 p^{3}-2p\right) +\left(-2p^{3}-8 p^{2}+4\right)$

$= p^{4}+4 p^{3}-2p-2p^{3}-8 p^{2}+4$

Arrange and add/subtract same powers.

$= p^{4}+(4 p^{3}-2p^{3})-8 p^{2}-2p+4$

$= p^{4}+2 p^{3}-8 p^{2}-2p+4$

Hence $g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4$
