Answer:

3(8+4)

Step-by-step explanation:

You have  to find the sum of eight and for ( which means ad 8 to 4). Then you must multiply that answer by three. The reason you put a parentheses around the 8+for is because of PEMDAS which is the order you must do All expressions. The P stands for parentheses E stands for exponents the M stands for multiplication the D stands for division the A stands for addition and the S stands for subtraction. So without the parentheses around the 8+ for you and multiply 8 times three first and then add four which is not the correct answer.

What is the value of X?
Troyanec [42]

All three sides of the triangle are the same so youcan set two of the equations equal to each other and solve for x:


4x-10 = 3x +2

Add 10 to each side:

4x = 3x + 12

Subtract 3x from each side:

x = 12

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give
Inga [223]

Answer:

y = 1/e

y = 0.37

Step-by-step explanation:

y = (ln x)/x; (e, 1/e)

Step 1

Find the point of tangency.

It's given as (e,1/e) or (2.72,0.37)

Step 2

Find the first derivative, and evaluate it at x=e

Using product rule.

d(uv) = udv + vdu

Where u = lnx and v = 1/x

du = 1/x , dv = -1/x^2

f'(x) = -lnx/x^2 +1/x^2

f'(x) = (1-lnx)/x^2

At x = e

f'(e) = (1-lne)/e^2

f'(e) = 0

The slope of the tangent line at this point is m= 0

Step 3

Find the equation of the tangent line at (e,1/e) with a slope of m=0

y−y1 = m(x - x1)

y-(1/e) = 0(x-1)

y = 1/e

y = 0.37
