Hey there !

Let us take the length of the shorter piece as ' x '

Then, the longer piece would be ' 3 + 5x '

Total = 45

x +  5x + 3 = 45

6x + 3 = 45

Subtracting 3 on both sides

6x = 42

dividing by 6 on both sides

x = 7

shorter wire = 7 ft

longer = 45 - 7

=  38 ft

Hope my answer helps!

Long piece:  5x + 3

Short piece: x

Long   + Short = Total

5x + 3 +    x     = 45

6x + 3 = 45

6x = 42

x = 7

Long piece:  5x + 3   = 5(7) + 3   = 35 + 3   = 38

Answer: short = 7 ft, long = 38 ft

What is the equation of the following line? Be sure to scroll down first to see
andriy [413]

Answer:

y = 6x + 0

Step-by-step explanation:

Equation of a line

y = mx + c

Given

( 0 , 0) ( -1/2 , -3)

find the slope m

m = y2 - y1 / x2 - x1

x1 = 0

y1 = 0

x2 = -1/2

y2 = -3

Insert the values

m = y2 - y1 / x2 - x1

m = -3 - 0 / -1/2 - 0

= -3/-1/2

Minus cancels minus

= 3/1/2

= 3/1 ÷ 1/2

= 3/1 × 2/1

= 6/1

= 6

m = 6

Substitute any of the two points given into the equation of a line

y = mx + c

Where

y - intercept point y

x - intercept point x

m - slope of the line

c - intercept

(-1/2 , -3)

x = -1/2

y = -3

-3 = 6(-1/2) + c

-3 = -6/2 + c

-3 = -3 + c

-3 + 3 = c

c = 0

y = 6x + 0

The equation of the line is

y = 6x + 0
