Answer:

x=3

Step-by-step explanation:

The line of reflection would be at x=3. It’s like a mirror. The reflection is backward, but the same distance from the line of reflection, so the line needs to be halfway between the two shapes. Since C is at 4 and C’ is at 2, the line of reflection has to be at 3.

JulijaS [17]

Answer:

See explanation

Step-by-step explanation:

Use formula

$I=P\cdot r\cdot t,$

where

I = interest,

P = principal,

r = rate (as decimal),

t = time

In your case,

$P=\$1,539\\ \\r=0.01$

If $t_1=5$ years, then

$I_1=1,539\cdot 0.01\cdot 5=76.95$ and the whole sum is $\$1,539+\$76.95=\$1,615.95$

If $t_2=10$ years, then

$I_2=1,539\cdot 0.01\cdot 10=153.9$ and the whole sum is $\$1,539+\$153.9=\$1,692.9$

If $t_3=15$ years, then

$I_3=1,539\cdot 0.01\cdot 15=230.85$ and the whole sum is $\$1,539+\$230.85=\$1,769.85$

What is a simlified form of x+3 over x^2-x-12 multiplied by x-4 over x^2-8x+16?

Vesnalui [34]

Answer:

$\large\boxed{\dfrac{x+3}{x^2-x-12}\cdot\dfrac{x-4}{x^2-8x+16}=\dfrac{1}{x^2-8x+16}}$

Step-by-step explanation:

$\dfrac{x+3}{x^2-x-12}\cdot\dfrac{x-4}{x^2-8x+16}=\dfrac{x+3}{x^2+3x-4x-12}\cdot\dfrac{x-4}{x^2-8x+16}\\\\=\dfrac{x+3}{x(x+3)-4(x+3)}\cdot\dfrac{x-4}{x^2-8x+16}=\dfrac{x+3}{(x+3)(x-4)}\cdot\dfrac{x-4}{x^2-8x+16}\\\\\text{cancel}\ (x+3)\ \text{and}\ (x-4)\\\\=\dfrac{1}{x^2-8x+16}$
