Solve the following equation for x.
5x + 15 = - 45

Answers

Answer 1

Answer:

-12

Step-by-step explanation:

5(-10)=-60

-60+15=

-45

Answer 2

Answer:

-12

Step-by-step explanation:

Reorder the terms:

15 + 5x = -45

Solving

15 + 5x = -45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 5x = -45 + -15

Combine like terms: 15 + -15 = 0

0 + 5x = -45 + -15

5x = -45 + -15

Combine like terms: -45 + -15 = -60

5x = -60

Divide each side by '5'.

x = -12 :)

Using two or more complete sentences, describe how you can find a vector parallel to B = (-2,3) .

Answers

Answer:

To find a vector parallel to B, such vector must be a scalar multiple of B.

Step-by-step explanation:

Two non-zero vectors are parallel if they are scalar multiples of one another.

A vector parallel to B must be a scalar multiple of B.

let the vector parallel to B be A, then their scalar multiple is given as;

A = kB

A = k(-2, 3)

where;

k is scalar

Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.

131 + 5 = 136

131 - 5 = 126

The question is probably asking what is 131 plus negative 5, hence the correct equation is; 131 - 5, and the correct answer is 126.
