PART A
alligators:
x = total number of alligators
n = number of years
x=20*1.25^n
crocodiles:
y = total number of crocodiles
n = number of years
y=25+10n
PART B
alligators
x=20*1.25^4 = 48.82 round up to 49
crocodiles 25 +10(2) = 25+20 = 45
Part C
7 years
20(1.25^n)=25+10n
1.25^n=1.25+0.5n
n=7
check:
alligators 20+1.25^7 = 95.36
crocodiles = 25+10(7) = 95
Slope intercept form:
y=mx+b
Where:
m= slope ( y variation/ x variation)
b= y-intercept (where the line crosses the y-axis)
By looking at the graph we can see that the line crosses the y-axis at -2.
b=-2
slope = rise/ run= 3/1 = 3
Equation:
y= 3x-2
(5x+15)(6x-10)
= 30x^2 + 30x - 50x - 150
= 30x^2 - 20x - 150
Answer:
15
Step-by-step explanation:
Complementary angles mean the two angles add up to 90 degrees. So the step by step would look like this;
3x + 10 + 2x + 5 = 90
5x + 15 = 90
5x = 90 - 15
5x = 75
x = 75/5
x = 15 :)
I think the answer is $440. 5% is $10 1% is $2 = $12 x 2 = $24
$24 x 10 = $240
200+240=440
