Answer:
C = 20 + 0.001x
C = $20 + $0.001x
Step-by-step explanation:
Let x represent the number of minutes spent talking on the phone.
Given;
Fixed monthly charge F = $20
Charge per 10 minutes V = $0.01
Charge per minute = V/10 = $0.01/10 = $0.001
The equation to model the cost of a monthly cell phone bill;
Total cost = fixed cost + variable cost
C = F + (V/10)x
Substituting the values;
C = 20 + 0.001x
Hey those are linear functions, gotta find Y or X and draw on two axis X/Y. in first y = 4/9x + 1/9. in second y = X/2 - 2.
Answer:
151
Step-by-step explanation:
Let x = the smaller integer and y = the larger integer.
We have two conditions:
(1) x + 1 = y
(2) y = 2x - 149 Substitute (1) into (2)
x + 1 = 2x - 149 Add 150 to each side
x + 150 = 2x Subtract x from each side
x = 150 Substitute into (1)
150 +1 = y
y = 151
The larger integer is 151.
<em>Check:
</em>
(1) 150 + 1 = 151
151 = 151
(2) 151 = 2×150 -149
151 = 300 -149
151 = 151
