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
Answer:
Step-by-step explanation:
f(x) = |2x−1|+3, reflected over the y-axis becomes
g(x) = |-2x−1|+3
We needed the point (0.5, 3) to go to the other side of the y-axis to get the point (-0.5, 3).
Statement B would be the correct answer because the y's stayed the same. Having a dilation of 1/2 means that both the x and y from the original point will be multiplied by 1/2. Every other answer is multiplied by 1/2, meaning B is the correct answer.
