Let x represent the width. Since the length is 3 more than 4 times the width, that would be equal to 3+4x. The perimeter is the sum of all sides, so that would be x+x+3+4x+3+4=86. Combine like terms, which would result in 10x+6=86. Subtract 6 from both sides giving you 10x=80. Divide by 10 giving you x=8. That means that the width is 8. The length is 3+4x. Substitute 8 for x giving you 3+4(8). Multiply, giving you 3+32, then add, which would give you 35.  35 is the length.

Write an equation for the line that is parallel to the given line and that passes through the given point. y = 1/2x - 8; (-6, -1
Allisa [31]

Answer:

y = 1/2x - 14

Step-by-step explanation:

Parallel lines have the same gradient

So,

gradient for second line = gradient of the first line = 1/2

Also,

the line passes through (-6,-17)

So, we can find the y-intercept by substitution

y = mx + c

-17 = (1/2 * -6) + c

-17 = -3 + c

c = -14

So,

the equation is y = 1/2x - 14
