A) y = 27x + 3
b) domain: 10<x<15
range: 273<y<408
Answer:
There is not enough to solve.
Step-by-step explanation:
Answer:
x + (5x-9)
Step-by-step explanation:
x stands for the number of coins Nancy has
Kevin has 9 less than 5 times what Nancy has, so his part of the expression is 5x-9
To find the total number of coins they have, you have to add Nancy's number of coins x plus Kevin's number of coins 5x-9
x + (5x-9)
But you have to put parentheses around Kevin's 5x-9 so that part of the expression is calculated first, as per order of operations
Number of possible combinations = (4x3) ÷ 2 = 6
Answer: There are 6 possible combinations.
