Answer:
I assume the answer would be that f(x) = 6(x) increases over the interval x = 3 to x = 4
Step-by-step explanation:
6 x 3 is 18 and 6 x 4 is 24, so over the interval x = 3 to x = 4 f(x) would increase.
Answer:
Son of 15 years $180
Son of 10 years $120
Step-by-step explanation:
15 + 10 = 25
25 300
15 x = 300*15/25
x = 180
25 300
10 x = 300*10/25
x = 120

Answer:
B. 4
Step-by-step explanation:
A direct proportion has the form
y = kx or k=y/x,
where k is the proportionality constant.
Let's test some points.
Second point
k = 8/2 = 4
Fifth point
k = 23/5.75 = 4
You will get the same result for every point, so the constant of proportionality is 4.
Hi,
Let Sydney's age be x.
Devaughn=(x-15)
x+(x-15)=37
x+x-15=37
2x-15=37
2x=37+15
2x=52
x=52/2
x=26
Sydney is 26 years old.
Hope this Helps you.
