Answer:
The definition of a vector that you learn in linear algebra tells you everything you need to know about what a vector is in any setting. A vector is simply an element of a vector space, period. ... So, to say that a vector is a column of numbers, or a geometric object with magnitude and direction, is incorrect
Step-by-step explanation:

If the perimeter is known / given and is 6x, you can find the length of the unknown side by adding up the lengths of the other two sides and subtracting this sum from 6x:
6x - (x+3 + 2x + 4) = 6x - x - 3 - 2x - 4
Combining like terms, 3x - 7 represents the length of the unknown 3rd side.<span />
Answer:
The value of x is -0.5.
Step-by-step explanation:
The given equation is
Use distributive property to solve the above equation.
Add 4x both sides.
Subtract 16 from both sides.
Divide both sides by 8.
Therefore value of x is -0.5.
M = -2/3, B(2, -5), x₁ = 2, y₁ = -5
y - y₁ = m(x - <span>x₁)
</span>y - -5 = -(2/3)(x - 2<span>)
</span>
3(y + 5) = -2(x - 2)
3y + 15 = -2x + 4
3y + 2x = 4 - 15
3y + 2x = -11
