Answer:
The answer would be 257
Step-by-step explanation:
10x + 3(2x + 5) = 19
10x + 6x + 15 = 19
16x + 15 = 19
16x = 4
x = 1/4
2(1/4) + 5
.5 + 5
y = 5.5
(1/4, 5.5) is your final answer
Answer:15/31
Step-by-step explanation: because there are 31 kids in all and 15 of them are boys so 15/31
For this case we have the following equation:

Where, by definition, we have the following variables:
d (x): the daily expense per truck (in dollars)
x: the daily mileage
Therefore, the domain of the function is given by:

Equivalently:
[0, ∞)
Answer:
The input for the function includes all positive real numbers
option d.
The answer is 25centimeters. This is the answer because you have to multiply 10cm by 5 years then divide that by 2 since it grows 10 cm every 2 years.
