The slope is negative one half because perpendicular lines always have slopes that are opposite reciprocals
meaning not only are they reciprocals meaning 1 over the number (or flipping the numerator and the denominator of a fraction) you also change the sign
So, after one year will will have the new population of 23 000 * (100 %+2%)
(the 100 % is the old population and the 2% is the increase), that is:
23000*1.02=23460
(102 % can be represented as 1.02)
And for the next years, we have to repeat the procedure.
a more generic rule would be:
y=23000*
(x is the number of years passed)
Answer: 8y
Step-by-step explanation:
The top and bottom are the same length:
5x +10 = 40
Subtract 10 from each side:
5x = 30
Divide both sides by 5:
x = 30/5
x = 6
144 (12x12) because you have to times 12 by itself because there’s a 2 so 12x12
