Answer:
x = 3
Step-by-step explanation:
Given
7(x + 2) - 5 = 30 ( add 5 to both sides )
7(x + 2) = 35 ( divide both sides by 7 )
x + 2 = 5 ( subtract 2 from both sides )
x = 3
Only 25 and 28 are functions.
A function must have only one y value per x value. For 26, the y value of 0 and multiple others have two different y values. For 27, all x values less than 0 have multiple y values.
well and 300% increase means you multiply by 3 and then add the original number
in this case 300% of 25 is 75 and its an increase so 25+75=100
the answer is 100
1. 15 dollars
2. Deposit=15*month+105
3. Deposit=15*12+105=$285
4.
500=15*month+105
395=15*month
26.33=month
Round up to 27 for the nearest whole month, so month 27.
Hope this helps!
