Julia works for a company selling light bulbs. She sells fluorescent light bulbs for $5 a piece and incandescent light bulbs for $2. To meet her quota, she needs to sell over 100 light bulbs and make at least $350. If the solution region is the amount of light bulbs Julia needs to sell to meet her quota, which graph's shaded area represents the solution region? A.Y B.W C.Z D.
1 answer:
The solution to the amount of light bulbs Julia needs to sell to meet her quota is represented by the shaded area in graph X .
<h3>What is an
equation ?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the incandescen t light bulbs and y represent the fluorescent light bulbs. Therefore:
x + y > 100 (1)
Also:
2x + 5y ≥ 350 (2)
The solution to the amount of light bulbs Julia needs to sell to meet her quota is represented by the shaded area in graph X .

1/2*2a= 1a -6b*1/2=-3b 8* 1/2= 4 so 1a-3b+8
You are correct
for example f(1) = 3
and f(2) = f(2-1) - 2
= f(1) - 2
= 3 - 2 = 1
17 This is gonna be confusing but this is how you solve stuff like this 8 x 8 = 64 15 x 15 = 225 64 + 225 = 289 Find the square root of 289 17
Answer:
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
Step-by-step explanation:
longest section 1 = a
mid length section 2 = b
shortest section 3 = x
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
5x + 5 = 40
5x = 35
x = 7
b = 12
a = 21
