Answer:
sqrt(x+7) - log(x+2)
Step-by-step explanation:
f(x) = sqrt(x+7)
g(x) log(x+2)
f(x) - g(x) = sqrt(x+7) - log(x+2)
Answer:10
Step-by-step explanation:
3x - 1 = 5x - 11
Add 1 to both sides.
3x = 5x - 10
Subtract 5x from both sides.
-2x = -10
Divide by -2.
x = 5
The answer is C, because there are double the amount of nickels than dimes and 24 nickels time 5 cents is $1.20 and 12 dimes times 10 cents is $1.20 and if you add those together you get $2.40, so C.
