2x + 8 = 16
2x = 16 - 8
2x = 8 (divide both sides by 2 to get x)
2x/2 = 8/2
x = 4
3x-26=10
3x=10+26
3x=36
X=12
8% or 8 cents per dollar.
To find the answer, just divide the extra 32 cents charged by the 4 dollars spent to find the amount per dollar, and you should get 8, or 8% tax.
Answer:
2(x-3/4)^2 - 49/8 = 0
Step-by-step explanation:
2x^2 - 3x - 5 = 0
First take out the 2: 2 [x^2 -3/2x - 5/2] = 0
Now complete the square inside the square brackets: 2 [(x-3/4)^2 - 9/16 - 5/2] = 0
Simplify inside the square brackets: 2 [(x-3/4)^2 - 49/16] = 0
Now times out the square brackets: 2(x-3/4)^2 - 49/8 = 0
And we're done!
We have to find how can someone convert the temperature from degrees Farhenheit to degrees Celsius using the function. The temperature in degrees Celsius is equal to the temperature in degrees Farhenheit minus 32 times 5/9. Or C ( F ) = ( F - 32 ) * 5/9. For example: the temperature is F = 50°; C ( 50 ) = ( 50 - 32 ) * 5/9 = 18 * 5/ 9 = 10 °C. Answer: The function is: C ( F ) = ( F - 32 ) * 5/9.
Hope this helped.
