Determine whether the given set S is a subspace of the vector space V.A. V is the vector space of all real-valued functions defi
Nataly [62]

Answer:

Check the explanation

Step-by-step explanation:

kindly check the attached image below to Determine whether the given set S is a subspace of the vector space <u><em>(which is contained within a different vector space. So all the subspace is a kind of vector space in their own way, although it is also defined relative to some of the other larger vector space. The linear subspace is more often than not simply called a subspace whenever the situation serves to differentiate it from other types of subspaces.)</em></u> V.A

What is the slope of a line that passes through the points (-2,3) and (4,-12)
posledela

Answer:

m = -5/2

Step-by-step explanation:

Solve for slope with the following equation:

<em>m </em>(slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(4 , -12) = (x₁ , y₁)

(-2 , 3) = (x₂ , y₂)

Plug in the corresponding numbers to the corresponding variables:

<em>m </em>= (3 - (-12))/(-2 - 4)

<em>m</em> = (3 + 12)/(-2 - 4)

<em>m </em>= (15)/(-6)

Simplify the slope:

<em>m</em> = -(15/6) = -5/2

-5/2 is your slope.
