Subtract to find out how much she spent:
30 - 27.90 = 2.10
Divide that by the cost per minute:
2.10 / 0.14 = 15
The call was 15 minutes.
I think you’re answer is option 1: 3x^2+5.
Explanation:
Evaluate f(x^2+2) by substituting in the value of g into f.
f(x^2+2)=3(x^2+2)-1
Then apply distributive property.
f(x^2+2)=3x^2+3•2-1
Then multiply 3 by 2.
f(x^2+2)=3x^2+6-1
Then subtract 1 from 6.
f(x^2+2)=3x^2+5
Answer:
Integers are the set of whole numbers and their opposites. Whole numbers greater than zero are called positive integers. Whole numbers less than zero are called negative integers. The integer zero is neither positive nor negative, and has no sign. Two integers are opposites if they are each the same distance away from zero, but on opposite sides of the number line. Positive integers can be written with or without a sign. an example with numbers is 17positive and 17 negative both are 17 (clicks/jumps/etcetera) away from 0. There is no 0 positive or negative.
