The answer is seven im sure
Answer:
3,000
Step-by-step explanation:
Create 2 expressions to represent the cost and the revenue, where x is the number of newspapers:
2x + 15,000 will represent the cost
5x + 6,000 will represent the revenue
Set the expressions equal to each other and solve for x:
2x + 15,000 = 5x + 6,000
15,000 = 3x + 6,000
9,000 = 3x
3,000 = x
So, 3,000 newspaper copies have to be sold to break even

Answer:
a) y=1/3 sqrt(x+1)
b) 2/3
c) 224
Step-by-step explanation:
a) y varies directly to sqrt(x+1)
means there is some constant k such that y=ksqrt(x+1)
y=1 when x=8 (plug this in and find k) 1=ksqrt(8+1)
1=ksqrt(9)
1=k(3)
1/3=k
So the equation is y=1/3 * sqrt(x+1)
a) y=1/3 *sqrt(x+1)
b) what is y when x=3 if you have y=1/3 * sqrt(x+1)
Plug in 3 for x
y=1/3 *sqrt(3+1)
y=1/3 *sqrt(4)
y=1/3 *2
y=2/3
b) 2/3
c) what is x when y=5
Plug in 5 for y
5=1/3 *sqrt(x+1)
multiply both sides by 3
15=sqrt(x+1)
square both sides
225=x+1
subtract 1 on both sides
224=x
c) 224
Answer:
False
Explanation:
No, a triangle cannot be constructed with sides of 2 in., 3 in., and 6 in.
For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.
