to work it out just go output f (x) - input x so, 3 - 1 = 2 and double check this using your next equations 4 - 2 = 2
Hello!
<u><em>Explanation: Addition property of equality is adding the same number to both sides of an equation does not change the equation.</em></u>
<u><em>a+c=b+c</em></u>
<u><em>First, add by 23 both sides of an equation.</em></u>
<u><em>y-23+23=-5+23</em></u>
<u><em>And then, simplify.</em></u>
<u><em>23-5=18</em></u>
<u><em>It changes negative to positive sign.*</em></u>
<u><em>Final answer is y=18</em></u>
<u><em>Hope this helps!</em></u>
<u><em>Thanks!</em></u>
<u><em>Have a great day!</em></u>
Answer:
-2
Step-by-step explanation
If you are supposed to add them up then, 4 + (-8) = -4, -4 + 9 = 5, 5 + (-7) = -2
You times the number by its self 3 times for ex. you have 4 ^cubed it would be 4*4*4=64
The length would be 40 feet... 100*2=200/5=40
hope this helps!
