Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 7 ) and (x₂, y₂ ) = (3, 19 )
m = 
= 
= 4
The line crosses the y- axis at (0, 7 ) ⇒ c = 7
y = 4x + 7 → A
x. 250
_____ _____
7.30 100
cross multiply
100x = 1825
divide the 100
x = 18.25
(550*4.4)/100=24.2
24.2/12=2.016 $ in month
2.016*6=12.10 $
Hello from MrBillDoesMath!
Answer: factor = 4
Discussion:
Look at the sequence of numbers
1/64, 1/16, 1/4, 1, 4
It's seems clear that multiplying a term by 4 gives the next term in the sequence.
Thank you,
MrB
