16(2+5) since when you use distributive property, 16*2= 32 and 16*5= 80

Ludmilka [50]

The answer is 280 times, because 50 x 10 = 500, and the coin is fair, so you have to do 28 x 10, which equals 280. So the answer is 280 times. :D Glad I could help!

Answer:

Part 1) No

Part 2) Option 4. $f^{-1}(x)=-\frac{1}{3}x+3$

part 3) $f^{-1}(9)=4$

Step-by-step explanation:

Part 1) we have

$f(x)=8x-3$

$g(x)=(x+8)/3$

Find the inverse of f(x) and then compare with g(x)

Let

y=f(x)

$y=8x-3$

Exchange the variables x for y and y for x

$x=8y-3$

Isolate the variable y

$8y=(x+3)$

$y=(x+3)/8$

Let

$f^{-1}(x)=y$

$f^{-1}(x)=(x+3)/8$

therefore

the functions f(x) and g(x) are not inverses of each other

Part 2) we have

$f(x)=-3x+9$

Let

y=f(x)

$y=-3x+9$

Exchange the variables x for y and y for x

$x=-3y+9$

Isolate the variable y

$3y=-x+9$

$y=(-x+9)/3$

Let

$f^{-1}(x)=y$

$f^{-1}(x)=(-x+9)/3$

$f^{-1}(x)=-\frac{1}{3}x+3$

Part 3) we know that

For $x=4$ , $f(x)=9$

For $x=9$ , $f^{-1}(9)=4$

Vonda has 3 more quarters than dimes in her pocket. She has no other coins. The total value of her coins is $1.80. How many quar

yuradex [85]

0.10x+0.25(x+3)=1.80
0.10x+0.25x+0.75=1.80 
0.35x=1.80-0.75=1.05 
x=1.05/0.35=3 
Therefore,Vonda has 3 dimes and 6 quarters with her
