<h3>Answer:      y - 4 = -2(x - 5)</h3>

==================================================

Explanation:

Point slope form is

y - y1 = m(x - x1)

where m is the slope and (x1,y1) is the point the line goes through.

Parallel lines have equal slopes but different y intercepts. The given equation y = -2x-3 has a slope of -2, meaning that m = -2 is also the slope of the mystery parallel line.

-2 will go in the second box that's just to the left of the parenthesis.

The coordinates of (5, 4) will go in the other remaining boxes to finish off the equation.

We go from this

y - y1 = m(x - x1)

to this

y - 4 = -2(x - 5)

F(x) = -x - 3 Find f(-4) f(-4) = -(-4) -3
skelet666 [1.2K]

Answer:

\boxed{ \bold{ \boxed{ \sf{f( - 4) = 1}}}}

Step-by-step explanation:

Given, f ( x ) = - x - 3

Let's find the value of f ( - 4 )

\sf{f( - 4) =  - ( - 4) - 3}

We know that , ( - ) \times ( - ) = ( + )

⇒\sf{ 4 - 3}

Subtract 3 from 4

⇒\sf{1}

Hope I helped!

Best regards!!

Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 1013 kilometers. What is the distance
aalyn [17]
6.8 x 10^13 = 68,000,000,000,000
9.46 x10 ^12 = 9,460,000,000,000

6.8 x 10^13  *  1 light year / 9.46 x 10^12 = 7.188 light years.

A deposit of $6,500 was invested and has grown to $8,300 in 5 years. The growth in value was via simple interest, calculated on
bagirrra123 [75]

Answer: 5.5%

Step-by-step explanation:

Since the money invested has grown to $8300 and the principal was $600, this means the interest is:

= $8300 - $6500

= $1800

Simple interest = (Principal × Rate × Time)/100

1800 = (6500 × Rate × 5)/100

Cross multiply

1800 × 100 = 32500 × Rate

Rate = 180000/32500

Rate = 5.5%
