The value of n such that the number n and -3/4 are additive inverses is 3/4

<h3>How to determine the value of n?</h3>

The statement is given as:

The number n and -3/4 are additive inverses

The above statement means that

n = -1 * -3/4 --- by the definition of additive inverses

Next, we evaluate the product of -1 and -3/4

n = 3/4

Hence, the value of n such that the number n and -3/4 are additive inverses is 3/4

7 = -x+3. Consider the line y = Find the equation of the line that is parallel to this line and passes through the point (-5, 6)
artcher [175]

Answer with explanation:

The equation of line is, y= -x +3

→x+y-3=0---------(1)

⇒Equation of line Parallel to Line , ax +by +c=0 is given by, ax + by +K=0.

Equation of Line Parallel to Line 1 is

  x+y+k=0

The Line passes through , (-5,6).

→ -5+6+k=0

→ k+1=0

→k= -1

So, equation of Line Parallel to line 1 is

x+y-1=0

⇒Equation of line Perpendicular  to Line , ax +by +c=0 is given by, bx - a y +K=0.

Equation of Line Perpendicular to Line 1 is

  x-y+k=0

The Line passes through , (-5,6).

→ -5-6+k=0

→ k-11=0

→k= 11

So, equation of Line Parallel to line 1 is

x-y+11=0
