Answer:
y = -1/2x +11/2
Step-by-step explanation:
The slope of the line is ...
m = (y2 -y1)/(x2 -x1)
m = (1 -2)/(9 -7) = -1/2
The y-intercept is ...
b = y -mx
b = 2 -(-1/2)(7) = 11/2
Then the slope-intercept equation is ...
y = -1/2x +11/2
_____
<em>Alternative solution</em>
A general form equation for the line can be ...
(y1 -y2)(x -x1) -(x1 -x2)(y -y1) = 0
(2 -1)(x -7) -(7 -9)(y -2) = 0
x-7 +2y -4 = 0
x +2y -11 = 0 . . . . . general form equation
x +2y = 11 . . . . . . . standard form equation
Note that we want the x-coefficient to be positive, so we chose the order of the points to make that be the case.
Answer:
$72
Step-by-step explanation:
Interest= PNR
p = principal
n = number of years
r = rate of interest
i = 6% x 800 x 18/12
i = 72
It's a number that can evenly be divided by numbers other than 1 or itself.
Example: 8. You can multiply the factors 2 and 4 and get 8 other than multiplying 8 and 1.
Answer:
see below
Step-by-step explanation:
-2x^4-x^3+8x^2-12
First list by highest power to lowest power
The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial
If you really mean the multiply sign
-2x^4-x^3*8x^2-12
-2x^4 - 8x^5 -12
-8x^5 -2x^4 -12
This would be a 5th degree or quintic
I believe that you need to divide 4 by 8 to get $0.50 per juice box.
