Answer:
The answer is D.
Step-by-step explanation:
As the question say x represents number of minutes and y represents total amoumt so $5 and $10 is a fixed amount that are needed to pay for each month. So the expression for each month that is needed to pay is :
y = 0.99x + 5
y = 0.79x + 10
Answer:
2.84
Step-by-step explanation:
Recognize that 252 = 7*36
and so:
log base 7 of 252 = log base 7 of 36 + log base 7 of 7, or
log base 7 of 36 + 1
So the most you can simplify log base 7 of 252 is to write 1 + log base 7 of 36.
Or, if you want to use the change of base formula, you could do the following:
log 36
log base 7 of 36 = -------------- = 1.84
log 7
and so log base 7 of 252 would come out to
1 + log base 7 of 36 = 1 + 1.84 = 2.84
Check: does 7^2.84 = 252? YES. So we know that:
1 + log base 7 of 36 = 2.84
Answer:
The value of the expression at w=3 is;
Explanation:
Given the expression;
Then when w=3, the value of the expression is;
The value is gotten by replacing/substituting w with 3 in the expression;
Therefore, the value of the expression at w=3 is;
7.8
is the answer :) because you have to turn the fraction into a decimal then multiply by 3.
