N + d = 30
0.05n + 0.10d = 2.20
^^ ur system of equations
Let's see how much it would cost for 8 batteries by each package
1) 3.92 x 2 = 7.84
2) 7.60
the second package as it would be much cheaper
Answer:
4
Step-by-step explanation:
Answer:
The equation of the line would be y = .5x + 2.5
Step-by-step explanation:
In order to find this, we must first find the slope of the equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (2 - 3)/(-1 - 1)
m = -1/-2
m = .5
Now that we have the slope, we can use either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 3 = .5(x - 1)
y - 3 = .5x - .5
y = .5x + 2.5
(b+1)/2b
quotient = divided by
we're dividing a number that is 1 more than b (b + 1), with a number twice as large as b (2b).
