Y = mx + b
slope(m) = -2/3
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -2/3(-4) + b
1 = 8/3 + b
1 - 8/3 = b
3/3 - 8/3 = b
-5/3 = b
so ur equation is : y = -2/3x + (-5/3) which can be written as : y = -2/3x - 5/3
Looks like a geometric sequence
-15 each time
Hope this help :)
Answer:
The better buy is 2 ice cream cones for $3.00
Step-by-step explanation:
Step one:
given
You can buy 2 ice cream cones for $3.00
let us solve for the unit cost
3/2= $1.5 per ice cream cone
Step two:
You can buy 4 ice cream cones for $7.00
let us solve for the unit cost
7/4= $1.75 per ice cream cone
The better buy is 2 ice cream cones for $3.00 because a cone is $0.25 less expensive than 4 ice cream cones for $7.00.
Answer:
I'll setup the problem and you can do the computation
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
I = interest
P = deposit
r = interest rate per period
t = number of periods
P = $800
r = 0.02
t = 2
