1)~3x-7-2x+5=6\iff (3x-2x)+(-7+5)=6\iff\\\\ x-2=6\iff x=6+2\iff\boxed{x=8}\\\\
2)~A(x)=\dfrac{f(2)-f(-5)}{(2)-(-5)}=\dfrac{(2^2+7\cdot2+10)-((-5)^2+7\cdot(-5)+10)}{7}\\\\=\dfrac{(4+14+10)-(25-35+10)}{7}=\dfrac{28-0}{7}=\dfrac{28}{7}=4\iff\boxed{A(x)=4}

The price of a swimming pool
Goryan [66]

Answer:

  • Sales\:\:Price=List\:\:Price-Discount
  • Sales price= $1167.25 List price=L Discount=19.5\%\:of\:L=0.195L
  • 1167.25=L-0.195L

Step-by-step explanation:

The percentage discount is 19.5\%

The discount is always given on the list price.

Sales\:\:Price=List\:\:Price-Discount

Let the list price be L, then

List price=L

Sales price= $1167.25

Discount=19.5\%\:of\:L=0.195L

We substitute into the equation to get:

1167.25=L-0.195L

1167.25=0.805L

Divide both sides by 0.805

\frac{1167.25}{0.805}=L

1450=L

The list price of the swimming pool is $1450

Shkiper50 [21]

Answer:

$215.16

Step-by-step explanation:

Assuming he worked:

Tuesday - 4.14 hours

Wednesday - 3.14

Thursday - 7.14

Friday - 5.14

Add all the hours together: 4.14+3.14+7.14+5.14 = 19.56. Now times the hour by his rate of $11.

19.56(11) = $215.16

<span>v(x)=(s/t)
= (3x - 6) / (-3x+6)
= [3(x-2)] / [-3(x-2)] --> 3 is factored out
= 1/-1 </span>---> common terms are cancelled out. 
= -1 ---> This is the simplified formula.

To find the domain, we equate the denominator to 0.
-3x+6 = 0
3x = 6
x = 2
Domain: all values except 2.

w(x)=(t/s)(x)
= (-3x+6)x / (3x-6)
= [-3x(x-2)] / [3(x-2)] --> 3 is factored out
= -x --> The common terms are cancelled out. This is the simplified formula.

Solving for domain:
3x-6 = 0
3x = 6
x = 2
Domain: all values except 2.
