Another number will be negative.
Although you didn’t list any equations, here is the correct one:
15 + 5x = 25
1.5 twice a day makes it so it’s 3 miles total. Thus, you need to multiply that by 5 to get the total amount in one week.
x will solve for each evening per day.
Hope this helps!
Answer:
f(g(x)) = 72x^2+1
Step-by-step explanation:
f(x) = 2x^2 +1
g(x) = -6x
f°g(x) means f(g(x))
Take g(x) and substitute it in for x in f(x)
f(g(x)) = 2(g(x))^2 +1
=2(-6x)^2 +1
=2(36x^2) +1
=72x^2 +1
You can first distribute the number into the parenthesis: 3n + 2 - 8n. Now, combine the like terms (n): -5n + 2. It can either be -5n + 2 or 2 - 5n.
