Using any specific formula or what?
Answer:
If you are on USATestPrep (which you most likely are) the correct answer is C.
Step-by-step explanation:
C) y = 3b − 5
It is “5 fewer than 3 times”
This can help you to understand it
Answer:
£9.50
Step-by-step explanation:
if the price was reduced 70%, then Dave is paying 30% of the original.
0.3 of £ = 2.85
£ = 2.85 / 0.3
£ = 9.5
£9.50
We first get the gradient of the equation of a line by taking the
change in y over change in x
Hence our gradient will be
(6-9.5)/(8-1)=-3.5/7=0.5
Taking an arbitrary point(x,y) and using our gradient we get
and one of the points above we get
(y-6)/(x-8)=0.5
y-6=0.5*(x-8)
y-6=0.5x-4
y=0.5x+2 or y=1/2x+2
which is the line of our equation the answer we are
asked for.
