Perimeter: P=24 ftLenght: LWidth: W
The length is 2 ft longer than the width:(1) L= W+2 ft
Perimeter: P=2(W+L)P=24 ft2(W+L)=24 ftDividing both sides of the equation by 2:2(W+L)/2 =(24 ft)/2(2) W+L=12 ft
We have a system of 2 equations and 2 unkowns:(1) L=W+2(2) W+L=12
Using the method of substitution: Replacing L by W+2 in the second equation:(2) W+L=12W+(W+2)=12W+W+2=122W+2=12
Solving foe W2W+2-2=12-22W=10Dividing both sides of the equation by 2:2W/2=10/2W=5
Replacing W by 5 in the first equation:(1) L=W+2L=5+2L=7
Answers:What is the width?  5 ftWhat is the length? 7 ft

Rewrite it as a function and isolate y. ​
serious [3.7K]

Answer:

f(x) = -5x + 16

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

y + 5x = 16

Step 2: Put into slope-intercept form

  1. Subtract 5x on both sides; y = -5x + 16

Step 3: Rewrite in function notation

f(x) = -5x + 16

Help me please I need help!!!!
marta [7]

Answer:

Answer B (proportional)

Step-by-step explanation:

The variable y and x are related by the constant of proportionality "6" in the expression

y = 6 x

Such means that if x adopts whatever value, y is always proportional to that x-value, by the multiplicative factor 6.

y is proportional to x via the proportionality constant (it has to be always a multiplicative constant) "6"
