they did not have enough materials
Step-by-step explanation:
Answer:
5:2
Step-by-step explanation:
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=

Also y=

We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
Answer:
a. 0
Step-by-step explanation:
1. To find the slope given two points, use the following formula:

2.
would be the second y-value (in the second ordered pair), 2, and
would be the first y-value (in the first ordered pair), also 2.
3. Same for the x-values.
is -2 and
is 4
4. Now plug in the values.

5. This equals
which simplifies to 0

Answer:
104π in² ≈ 326.7 in²
Step-by-step explanation:
Put the given numbers in the surface area formula for a cylinder.
SA = 2πr(r +h)
SA = 2π(4 in)(4 in +9 in) = 104π in² ≈ 326.7 in²
