G(x) = 0 can never happen.
When x is 0, the answer is 4
When x is 1, the answer is 19.6
When x is 4, the answer is 66.4
According to Wolfram Alpha though, x is equal to -(10/39). If that's not a choice for you, don't worry about it. :)
7.C I think is the answer
Answer: c
Step-by-step explanation:
Answer=Carlos
If Jackie has 10 groups, with 3 in each groups, she has 30 total pennies.
10*3=30 pennies
If Carlos has 5 groups with 100 in each group, then Carlos has 500 pennies.
5*100=500 pennies
500 pennies is more than 30 pennies, so Carlos has more pennies
b - 10 = 7
Take 10 to the other side.
b = 17
Multiply by 4 to isolate b
b × 4 = 17 × 4
4 and 4 cancels out
b = 68
