Answer:
The second function represents an even function;
Step-by-step explanation:
A function f(x) is said to be even if f(x) = f(-x). All we need to do is replace x with -x in each equation, simplify it and assess whether the equation remains unchanged. If the equation is identical to the original one then it is said to be even. Another good example of an even function is the cosine function. Moreover, even functions have y-axis symmetry
Answer:
the solutions are 13 and -13
Step-by-step explanation:
13 x 13= 169
-13 x -13=169
a negative times a negative equals a positive
<em>So to solve for a variable, you have to isolate that variable onto one side.</em>
<h3>14.</h3>
Firstly, multiply both sides by j:
Next, divide both sides by k and <u>your answer will be: </u>
<h3>15.</h3>
Firstly, add g on both sides:
Next, multiply both sides by 5 and <u>your answer will be: </u>
<h3>16.</h3>
Firstly, subtract 5p on both sides:
Next, divide both sides by 9 and <u>your answer will be </u>
Answer:
$1000.
Step-by-step explanation:
Let x represent number of years.
We have been given that Tommy purchased a riding lawnmower with an original value of $2,500. The value of the riding lawnmower decreases by $300 per year. We are asked to find the value of lawnmower after 5 years.
Since the value of the riding lawnmower decreases by $300 per year, so value of lawnmower decrease in 5 years would be 5 times $300.
The final value of lawnmower would be initial value minus value decreased in 5 years.
Therefore, the value of lawnmower after years would be $1000.
Answer:
1. Exponent
2. Multiplication
3. Subtraction
4. Square root
5. Addition
6. Division?
<em>Note: I am not very sure about my answer because of two things. 1. The proper order for operating is PEDMAS (Parentheses, Exponent, Multiplication, division, addition, and subtraction). There is no Square root in that operation so I will consider it in the middle. 2. There is no division operation in this problem.</em>
