$190*3=$570
$0.20*600= $120
$570+$120= $690
Total cost of trip is $690
Answer:
no
Step-by-step explanation:
6^2+7^2=9^2
36+49=81
no its not a right triangle
5/100=0.05
0.05*45.90=2.295
$2.30 is the tax. Feel free to correct this If wrong.
Answer:
I am pretty sure it is the first one
Step-by-step explanation:
Because it is (1, 6) on the graph
Sooooooo. . . ye!
(I'm sorry I couldn't explain more detailed)
![\frac{3x}{x-4} - \frac{x+3}{x-4} = \frac{2x+7}{x^2-16}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7Bx-4%7D%20%20-%20%5Cfrac%7Bx%2B3%7D%7Bx-4%7D%20%3D%20%5Cfrac%7B2x%2B7%7D%7Bx%5E2-16%7D)
We factor the denominators
Factor x^2 - 16
x^2 - 4^2
We use a^2 - b^2 = (a+b)(a-b)
so x^2 - 4^2 = (x+4)(x-4)
Replace it in the given equation
![\frac{3x}{x-4} - \frac{x+3}{x-4} = \frac{2x+7}{(x+4)(x-4)}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7Bx-4%7D%20%20-%20%5Cfrac%7Bx%2B3%7D%7Bx-4%7D%20%3D%20%5Cfrac%7B2x%2B7%7D%7B%28x%2B4%29%28x-4%29%7D)
Excluded values are the values that makes the denominator 0
we have (x-4) and (x+4) in the denominator
We set the denominator =0 and solve for x
x-4 =0
Add 4 on both sides
x= 4
x+4=0
subtract 4 onboth side
so x= -4
Excluded values are x=-4 and x=4
