The answer is B because when you plug the value of x into the equation the answer will be y.
1. Collect like terms
(n-0.3n)+(4.5-3)
2. Simplify
0.7n + 1.5
Final Answer:
0.7n + 1.5

up six and to the left 5. going left is nevative so its negative 6 over 5
Answer:$3.25
Explanation:
Since the 7 min phone call is at 1.75, that means that one minute of phone call time is 0.25. 13 minutes would be 0.25*13=3.25
hope this helps
Answer:26
Step-by-step explanation:
Y=1.25^x-2/5-10
Take log of both sides
So Y+10=1.25^x-2/5
So log to base 10 of the two sides of the equation is
Log(Y+10)=X-2/5log1.25.
To make X the subject, divide both sides by log1.25.
Log(Y+10)/log1.25=X-2/5.
Recall that Y was given to be 115
It becomes log(115 +10)/Log1.25=x-0.4
21.64=x-0.4
X=25.6
