Answer:
and 
Step-by-step explanation:
The formulas for the area and perimeter of a rectangle are, respectively:
The perimeter is equal to:
Area is likewise equal to:
Then, equations are now described:
Likewise, the equation of area is simplified afterwards:
The area is reduced inasmuch as length is increased. Let assume that length is 100 meters. The length and width are described herein:
and
What you do here is you input 11 in as a value of x:
<span> f(-4) all you need to do is plug in x = -4 into equation
so </span><span>If f(x)=-8-5x then
f(-4) = -8 - 5(-4)
f(-4) = -8 + 20
f(-4) = 12
answer
f(-4) = 12</span>
Answer:
x =2
Step-by-step explanation:
The x- intercept is when y = 0
Hence, 5x - 2y = 10
5x - 2(0) = 10
5x = 10
Therefore, x = 2
Answer:
8 bulbs
Step-by-step explanation:
In the model, each + represents a dollar
4 +s for the shipping cost, 20 +s for the total cost.
Therefore we have 2x (since each bulb is $2) + 4 = 20
2x = 16
x = 8
