Answer: y=-4x-13

Step-by-step explanation:

To find the parallel line, we know that the slope must stay the same. Parallel lines NEVER touch or cross. Therefore, the slope MUST be the same. All we have to do is to find the y-intercept by plugging in the given point.

-5=-4(-2)+b [multiply]

-5=8+b [subtract both sides by 8]

b=-13

Now, we know that the equation is y=-4x-13.

Answer:

3, 50, 2

Step-by-step explanation:

By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.

3(n +25)= 5(10) +5( $\frac{2}{5} n$ )

3(n +25)= 50 +2n

To find the value of n, expand the bracket on the left hand side:

3(n) +3(25)= 50 +2n

3n +75= 50 +2n

Bring all n terms to one side, constants to the other:

3n -2n= 50 -75

n= -25

when solving a multi-step equation,does it matter in which order the operations are performed?explain.

rjkz [21]

Yes or course. PEMDAS
Parenthesis
Exponents
Multiplication-Division (solve left to right)
Addition- Subtraction (solve left to right)
example, lets take a simple equation.
32+6x7-1+4²
Let's solve it left to right
You're answer would be 281
But when using PEMDAS your answer is- 89
