4/5 would be the slope, the y-intercept is -3
Answer:
Step-by-step explanation:
Ok, so if there is no number in front of a variable (the letters), there is always a one. So you multiply them like this:
7 x 1b x 4 x 1a x 2 = <em>56ba</em>
1c x 5 x 1b x 4 x 1a = 20cba
Since there is only a 1 in front of the variables, you can basically just multiply the numbers without variables and then mutiply that times one. Don't forget to add the variables into the answer.
6 x 1p x 4 x 5 x 1w = 120pw
1t x 2 x 1t x 1s =

Answer:
a. C(x) = $16, if 0 ≤ x ≤ 10
C(x) = 2x - 4 if x > 10
b. Independent: Number of DVD rentals
Dependent: Monthly cost of rentals
c. $26
Step-by-step explanation:
a. The cost (C) of renting 'x' DVDs is given by:
If 10 ≤ x ≤ 10
C(x) = $16
If x > 10
C(x) = 16 + 2(x-10)
C(x) = 2x - 4
b. Since the cost depends on the number of DVD rentals, cost is the dependent variable and number of DVD rentals is the independent variable.
c. For x = 15:
C(15) = 2*15 - 4
C(15) = $26
It costs $26 to tent 15 DVDs in one month
5/16 = n/80
bring 80 over to the other side to leave n alone. 80 then gets a multiplication sign in front of it.
5/16 x 80=n
5/16=0.3125
0.3125x80=25
n=25
