Answer:

x = -3/7

Step-by-step explanation:

(2x-2)/x-3 = 5/6

(2x-2)×6 = 5×(x-3)

12x-12 = 5x-15

12x-5x = -15+12

7x = -3

x = -3/7

Final answer x is equal to -3/7.

2b plus 4a minus a minus 2 plus 12b

jarptica [38.1K]

The value of the expression 2b plus 4a minus a minus 2 plus 12b is 3a + 14b - 2.

Expression:

An expression is defined as the a combination of operators, constants and variables. And it may consist of one or more operands, and zero or more operators to produce a value.

Given,

Here we have the statement "2b plus 4a minus a minus 2 plus 12b".

Now, we have to find the simplified form of this statement.

In order to find the simplified form,

First we have to convert the statement into expression form, then we get

2b plus 4a minus a minus 2 plus 12b = 2b + 4a - a - 2 + 12b

Now, we have to combine the like terms, then we get,

=> (2b + 12b) + (4a - a) - 2

Perform the appropriate arithmetic operations, then we get the simplified form of the expression as,

=> 14b + 3a - 2

Now, we have to arrange them in order then we get,

=> 3a + 14b - 2

Consider the parametric curve:

11Alexandr11 [23.1K]

By the chain rule,

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\frac{\mathrm dy}{\mathrm dt}}{\frac{\mathrm dx}{\mathrm dt}}=\dfrac{4\sec t\tan t}{3\sec^2t}=\dfrac43\sin t$

When $t=\pi$ , we have

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{t=\pi}=\dfrac43\sin\pi=0$

Solve for x in the equation x2-8x+41=0

Alinara [238K]

Answer:

d) 4 ± 5i

Step-by-step explanation:

Here we have to use the quadratic formula.

x = $\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41

Now plug in the given values in the above formula, we get

x = $\frac{-(-8) +/- \sqrt{(-8)^2 - 4*1*41} }{2*1}$

Simplifying the above, we get

x = $\frac{8 +/- \sqrt{64 - 164} }{2}$

x = $\frac{8 +/- \sqrt{-100} }{2}$

[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]

x = (8 ± 10i )/2

Now dividing by 2, we get

x = 4 ± 5i

The answer is d) 4 ± 5i

Hope you will understand the concept.

Thank you.
