ANSWER
x = 1.2226
EXPLANATION
To solve this equation we have to apply the property of the logarithm of the base,
Thus, we can apply the natural logarithm - whose base is e, to both sides of the equation,
Now we apply the property of the logarithm of a power,
In our equation,
Then divide both sides by 4 and solve,
The solution to this equation is x = 1.2226, rounded to four decimal places.
Easy it's c you always match up the labels side to side on the equal signature
The step which is INCORRECT is no other than the step 4 is incorrect because it shows the incorrect substitution. The step one is correct, the chosen point (2,5) is on the line, same with step 2 where the chosen point (1,3) is also in the chosen line. While step 3 is also correct where the line runs 1 unit rises 2 units such as slope m = 2/1. To make step 4 correct, we should substitute slope in step 3 in the equation below:
(y - y1) = m (x-x1) where m is the slope, in this problem m is 2/1
using point (1,3) and slope m=2/1, we have:
y - 3 = 2 (x - 1)
Thus, step 4 in Talia's solution is incorrect.
<u>Answer:</u>
No
<u>Step-by-step explanation:</u>
We are given the following equation of a function and a table for the corresponding values of this function:
We are to determine if the equation and the table represent the same function.
To check that, we will substitute the value of x in the equation to see if it gives the same values of y as in the table.
---> (-30, 60)
---> (-28, 82)
---> )-26, 104)
Since these paired values differ from the ones given in the table. Therefore, table and equation do not represent the same function.
<span>A dinner bill of $31.37 had 6% tax added to that total. Let's solve for the amount of the tax:
=> 31.37 dollars * 0.06 = </span>1.8822 dollars is the tax which is 6%. Can be rounded to 1.88.
=> 31.37 - 1.8822 = 29.4878 is the original price
