Answer:

The answer would be 17/5

Step-by-step explanation:

To solve this, take the original equation and input 3/5 for p.

2/3p + 3

2/3(3/5) + 3

Now complete the multiplication followed by the addition.

2/3(3/5) + 3

2/5 + 3

17/5

Let f=​{(-1, 4)​,(1, 9)​,(4, 0)​} and g=​{(-1, -8)​,(2, -7)​,(4, 8)​,(5, -9)​}. Find​ g/f and state its domain.
tekilochka [14]

Answer:

g/f = {(-1, 2)}

domain of g/f = {-1}

Step-by-step explanation:

Given,

f =​ {(-1, 4)​,(1, 9)​,(4, 0)​},

g = ​{(-1, -8)​,(2, -7)​,(4, 8)​,(5, -9)​}

So, Domain of f = {-1, 1, 4},

Domain of g = {-1, 2, 4, 5}

Since,

\frac{g}{f}(x) = \frac{g(x)}{f(x)}

Thus, domain of g/f = Domain of f ∩ Domain of g = {-1, 4}

If x = -1,

\frac{g}{f}(-1) = \frac{g(-1)}{f(-1)}=\frac{-8}{-4}=2

If x = 4,

\frac{g}{f}(4) = \frac{g(4)}{f(4)}=\frac{8}{0}=\infty (\text{ not possible})

Hence, the domain of g/f = {-1}

And, g/f = {(-1, 2)}

Kevin and Randy Muise have a jar containing 70 coins, all of which are either quarters or nickels. The total value of the coins
Nikitich [7]

Answer:

50 nickels, 20 quarters.

Step-by-step explanation:

System of equations (q = # of quarters, n = # of nickels):

<em>q + n = 70, 0.25q + 0.05n = 7.50</em>

the first equation can be changed to q = 70 - n, so we are able to <em>substitute q with 70 - n</em>.

So, it will look like <em>0.25*70 - 0.25n + 0.05n = 7.50</em>. This can be simplified to <em>0.2n = 10</em>, which means that n = 50.

Knowing that we can solve <em>q + 50 = 70</em>, which means that q = 20.
