Hi there, we are going to set up a porportion. 640 miles/25 hours ÷ 25/25. That would equal 25.6 miles/1 hour. Therefore, the answer is 25.6 miles per hour.
The graph will be a set of disjoint points with coordinates [n, 0.5*(1+n)]

You just have to divide the length of the fabric by the length of the sections
Answer:
(p - 8)(p - 9)
Step-by-step explanation:
We need 2 numbers whose product is + 72 and whose sum = -17.
They are -8 and -9
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.
