Answer:
x = 54
Step-by-step explanation:
get the variable and numbers on different sides
x/3 + 6 = 12
x/3 + 6 - 6 = x/3
12 + 6 = 18
x/3 = 18
now im going to multiply each side by 3
x/3 x 3 = x
18 x 3 = 54
x = 54
Answer: 11, 30
Step-by-step explanation:
Given
There were a total of 41 national battlefields and national memorials
Suppose there are national battlefields
So, national memorials are
The sum of the two must be 41
So, there are 11 national battlefields and national memorials.
Answer: y - 3 = 0.041(x - 27)
Step-by-step explanation:
y = log3 x; (27, 3)
Step 1
Find the point of tangency.
It's given as (27,3)
Step 2
Find the first derivative, and evaluate it at x=27
Differentiating log3 x.
Note we can't directly differentiate log3 x, we need to convert it to natural log = ln.
Using change of base.
Log3 x = lnx/ln3
So,
d(lnx/ln3)/dx = 1/ln3 × 1/x
f'(x) = 1/xln3
f'(27) = 1/27ln3 = 0.041
The slope of the tangent line at this point is m= 0.041
Step 3
Find the equation of the tangent line at (27,3) with a slope of m=0.041
y−y1 = m(x - x1)
y - 3 = 0.041(x - 27)
