Answer:
y= 4/7x -1
Step-by-step explanation:
solve for y first in 4x-7y=9, which becomes y = 4/7x - 9/7, then since its a parallel line the slope stays the same which is 4/7. Then plug into this equation: y =mx+b, in which you plug in the point for the x and y values and you plug in the slope for m, so the equation becomes, 3 = (7)(4/7) + b and now solve for b in which b = -1 and now write the equation using all the corresponding things so the equation becomes: y= 4/7x -1
Answer:
Total Cost 
Step-by-step explanation:
Given:
Charges for an enlargement of 1 photograph = 
Delivery charge per order = 
Let number of enlargements of photograph in an order be 
We need to find the Total cost C of an order.
So the Total Cost would be equal to Charges for an enlargement of 1 photograph 
number of enlargements of photograph in an order plus Delivery charge per order.
Total Cost per order
Answer:

Answer:
0.303003000...
A rational number is either a terminating or non-terminating but recurring (repeating) decimal.
A rational number may be positive, negative or zero.
Examples:
