From the given information we can assume that (-1; 2) point is the same as x=-1 and y=2.

The easiest way to solve this problem is to put -1 and 2 instead of x and y

in this way you will get answer C

2 - 2 = (3/2)*(1 - 1) which means that 0 = 0 and this answer is correct.

Answer: C

Does anyone know how to solve the equation ln 2 - ln(x - 8) = 4, giving nearly 80 points
RoseWind [281]

Answer:

x= 8.1353

x= 8.135 (rounded to the nearest tenth-thousandths)

x= 8.14 (rounded to the nearest thousandths)

x= 8.1 (rounded to the nearest tenth)

Step-by-step explanation:

<u><em>Note I am not 100% sure with my answer</em></u>

2 − ln (x − 8)= 4

−ln (x − 8) + 2= 4

−ln (x − 8) + 2 + −2= 4 + −2

−ln (x − 8)= 2

−ln (x − 8)/−1= 2/−1

ln (x − 8)= −2

<solve for the logarithm (ln)>

ln (x − 8)= −2

e^ln (x − 8)= e^−2

x − 8= e^−2

x − 8= 0.1353

x − 8 + 8= 0.1353 + 8

x= 8.1353
