Answer:

Vertical asymptote at x = 8

Step-by-step explanation:

The given function can be rewritten as

x^2 - 64

f(x) = --------------

8(x - 8)

Even tho' this reduces to f(x) = x + 8, the function has a vertical asymptote at x = +8 because it becomes undefined there.

Answer:

$a=9, b=26, c=24$

Step-by-step explanation:

Let's expand the expression bit by bit.

$(x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6$ by FOIL.

We have that $(x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24$ .

So, the answer is $\boxed{a=9, b=26, c=24}$

Let Q= the number of quarters and D= the number of dimes.
Q+D= 40 coins
0.25Q+0.1D= $7.75
Rewrite equation 1 as: D = 40-Q and substitute into equation 2
0.25Q+0.1(40-Q)= 7.75 Simplify the left side
0.25Q+4-0.1Q= 7.75 Subtract 4 from both sides
0.25Q-0.1Q= 3.75 Convime like terms on left side
0.15Q= 7.75 Divide both sides by 0.15
Q=25 and D= 40-Q
D= 40-25 which is 15
So Jenna had 25 quarters and 15 dimes.
To check multiply 25 x 25 and 15x10 which equals 625 and 150 this equals 775 so this is 7.75

To solve this problem you can do a proportion
$\frac{x}{215} = \frac{35\%}{100\%}$
to find 'x', we have to cross multiply the numbers.
$215 \times 35$
and
$100 \times x$
this will get you
$7525 = 100x$
to get 'x', we have to divide by 100 on each side
$\frac{7525}{100} = \frac{100x}{100}$

your answer will be
$75.25 = x$
so, Chris must raise 75.25 dollars by himself
