Is (-6, -3) a solution to the equation y = 2x? Yes or No

Mathematics

KonstantinChe [14]4 years ago

Answer:

No

Step-by-step explanation:

If (- 6, - 3 ) is a solution then substituting x = - 6 into the equation should give a value of the y- coordinate - 3, that is

y = 2(- 6) = - 12 ≠ - 3

Thus (- 6, - 3 ) is not a solution of the equation

Look at this graph:
amm1812

For the given graph , slope of the line is equal to  ( 1 / 2 ).

As given in the question,

Form the given graph,

Scale is given by,

On x-axis each unit of the graph represent 1 unit.

On y- axis each unit of the graph represent 1 unit.

Consider two coordinates from the line of the graph,

( x₁ , y₁ ) = ( 1, 2 )

( x₂ , y₂ ) = ( 3, 3 )

Slope of the line = ( y₂ - y₁ ) / ( x₂ - x₁ )

 Substitute the value in the formula of the slope we get,

Slope of the line = ( 3 - 2 ) / ( 3 - 1 )

⇒ Slope of the line = 1 / 2

Therefore, for the given graph , slope of the line is equal to  ( 1 / 2 ).

The width of a rectangle is 5 centimeters less than the length. The area is 36 square centimeters. Find the length.
charle [14.2K]
If the width is Wthen the length is 2W-5 W(2W-5)=422W2-5W = 422W2-5W-42 = 0 Factor by grouping or do the quadratic equation.Multiply the coefficient of the squared term.. 2..by the constant ..-42..   2(-42)=-84Factors of -84 that add to the coefficient..-5.. ofthe W term are  7(-12)Replace the -5W with  -12W + 7W 2W2-12W+7W-42 = 02W(W-6) + 7(W-6)=0(2W+7)(W-6)=0
 Either:   2W+7 = 0   or   W-6 = 0             2W = -7           W = 6 cm             W = -7/2 cm

Since W will not be a negative, our width is 6cmThe length is 2W-5 = 2(6)-5=12-5 = 7 cm

Find dy/dx when y = Ln (sinh 2x). A. 2 cosh 2x B. 2 sech 2x C. 2 coth 2x D. 2 csch 2x
givi [52]
The function given is a composite function. Let's work from the outside in:
y=(ln(sinh(2x)))

First step:
\frac{d}{dx}[y]= \frac{d}{dx}[ln(sinh(2x))]

Now, let's work it out:
\frac{dy}{dx} = \frac{1}{sinh(2x) } *   \frac{d}{dx}[sinh(2x)]

Next step:
\frac{dy}{dx} = \frac{1}{sinh(2x) } * cosh(2x) *  \frac{d}{dx}[2x]

Next step:
\frac{dy}{dx} = \frac{1}{sinh(2x) } * cosh(2x) *2

Simplify:
\frac{dy}{dx} = \frac{2cosh(2x)}{sinh(2x) }

Simplify further:
\frac{dy}{dx} = 2 (\frac{cosh(2x)}{sinh(2x)})

Remember that:
{\frac{cosh(x)}{sinh(x)} = coth(x)

So, your final answer is:
\boxed{ \frac{dy}{dx} = 2coth(2x) }

So, your answer is C. Hope I could help you!
