Answer:
Statement 3
Step-by-step explanation:
y = -2/3x-24
Make x the subject
y + 24 = -(⅔)x
x = -(3/2)(y + 24)
Intersection variables
f^-1(x) = -(3/2)(x + 24)
Slope: -3/2
No domain restrictions
y-intercept: x = 0
-(3/2)(0+24)
-36
(0,-36)
x-intercepts: y = 0
0 = -(3/2)(x + 24)
x = -24
(-24,0)
Linear function, range is all real values of y
we are adding over 200,000 people<span> to this planet every day, or </span>140 people<span> every minute . That equals over </span>70 million<span> more people every year

24÷9=2.67.....................

If you don't know the first derivative of
, but you do for
and
, you can derive the former via the quotient rule:


or if you know the derivative of
:


As for the second derivative, you can use the power/chain rules:

or if you don't know the derivative of
,


which is the same as the previous result since

Answer: 30
Step-by-step explanation:
256+b^2=1156
b^2=900
b=30
