$2.99 + 7% of $2.99 =

= $2.99 + 7% * $2.99

= $2.99 + 0.07 * $2.99

= $2.99 + $0.21

= $3.20

At which values of X does the function F(x) have a vertical asymptote check all apply F(x) =3/(x+2) (x-7)

finlep [7]

Answer:

When x = -2 or when x = 7

Step-by-step explanation:

x+2 is a factor in the denominator. If x = -2, the factor becomes zero.

x-7 is a factor in the denominator. If x = 7, the factor becomes zero.

We can't have zero as a factor in a denominator because division by zero is not defined. It doesn't have any meaning.

A man has two more nickels than dimes. He has $1.15 in all. How many coins of each kind does he have?

zhannawk [14.2K]

Answer:

Man has 9 Nickels and 7 dimes.

Step-by-step explanation:

Let Number of dimes be x

and Number of Nickels be y

As Per given data he has two more nickels than dimes.

$y= 2+x\\$

As we know that

1 $\$$ = 100 cent

1 nickel is worth = 5 cents = $\frac{5}{100}$ = 0.05 $\$$

1 dime is worth = 10 cents = $\frac{10}{100}$ 0 .1 $\ $$

According to given data he has $\$\ 1.15$ total nickel and dimes

So the equation becomes,

$0.05y+0.1x=1.15$

but $y= 2+x$

$0.05(2+x)+0.1x=1.15\\0.1+0.05x+0.1x=1.15\\0.1+0.15x= 1.15\\0.15x= 1.15-0.1\\0.15x=1.05\\x=\frac{1.05}{0.15}= 7$

Substituting value of x in equation $y = 2+x$ we get

$y= 2+7 =9$

Man has 9 Nickels and 7 dimes.
