B and a
barry=b
a=older bro
a is 3 more than 3b
a=3+3b
sum is 28
a+b=28
3+3b+b=28
3+4b=28
minus 3 both sides
4b=25
divide both sides by 4
b=6.25
a=3+3b
a=3+3(6.25)
a=3+18.75
a=21.75
barry=6.25 years
21.75 years=older bro
Martin should save about $33.00 per week to purchase the gaming system and games in 10 weeks.
The parent function is: y = 2^x and it it transformed to: y = 2^x - 3. Both are exponential functions. First we can find the value of y, when x = 0. For the 1st function: y = 2^0 = 1 For the 2nd function: y = 2^0 - 3 = 1 - 3 = - 2 We can conclude that the 2nd value of y is 3 units lower than the first. Answer: This transformation is translation 3 units down.
