Answer:
Step-by-step explanation:
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Subtract 2/4 from both sides
x + 2/4 (-2/4) = 8/4 (-2/4)j
x = 8/4 - 2/4
Simplify
x = (8 - 2)/4
x = 6/4
Simplify. Change the improper fraction into mixed fraction
x = 6/4 = (4/4 + 2/4) = 1 2/4
1 2/4 simplified = 1 1/2
1 1/2 is your answer

Answer:
y-intercept: (0, 3) slope: 3
Step-by-step explanation:
There are two c's. You must pay attention to capitalization, there's a lowercase c and an uppercase C which represent two different variables. Also, the W is capitalized which could make your answer incorrect if you don't use the same notation.
Solving for small c..

So it's the answer shown in the picture, but it should be a capital W instead of a lowercase w.
Answer:
60ft
Step-by-step explanation:
Let's x, y be the width and length of the surrounding rectangle. Since the area is 450 sq feet, this means xy = 450 or y = 450/x
The perimeter of this rectangle is (since there are 3 sides only)
f(x,y) = 2x + y
This is something we need to minimize. We can start by substituting y = 450/x
f(x) = 2x + 450/x
Let's take the first derivative of this function and set it to 0




y = 450 / 15 = 30ft
so the minimum perimeter that needs taping over is
f(x,y) = 2x + y = 2*15 + 30 = 60ft
Slope is negative for each...Remember Y-int and rise/run for slope.
Y=mx+b
Y= -2/3X - 2
Y= -5/2x + 2
