You want me to find what x is? If so you will just do 50= 8x then you would divide 8 by 50 and get 6.25 as your answer! I hope this helps!

In your own words explain how you would solve this two step equation for the variable x. 9x-7=-7
NeX [460]

Answer:

Add 7 to both sides

Step-by-step explanation:

The equation has to be just x = y

There cannot be another number on the same side as the variable

Now that we did that, the equation is 9x = 0

x = 0

Well, that was easy lol

Derivatives of inverse trigonometric functions please explain answers
Jobisdone [24]

I'll explain how to do the first one:-

y = cos-1(x2)

This can be described as ' a function of a function'   x^2 is a function of x and cos-1(x^2) is a function of x^2.

We need to  apply the chain rule.

Personally I find this  easier to understand if i let u = x^2, so

If y = f(u) and u is a function of x then

dy/dx = dy/ du * du/dx

Here u = x^2  and y = cos-1(u)

du/dx = 2x

so dy/dx = d(cos-1(x^2) dx = dy/du * du/dx


= -1 / √(1 - u^2) * 2x

= -2x / √(1 - u^2)    

= -2x / √(1 - (x^2)^2)

= -2x / √(1 - x^4)

I hope this helps. but if not. you might like to employ the formulae in the question - The square boxes contain the 'u' s in my answer. These formulae are equivalent to my explanation.

Find value of x and y
marshall27 [118]

Answer:

x = 17\sqrt{3}, y = 34

Step-by-step explanation:

Since the triangle is right use trig ratios to find x and y

note exact values sin30° = \frac{1}{2}, tan30° = \frac{1}{\sqrt{3} }

sin30° = \frac{opposite}{hypotenuse} = \frac{17}{y}

multiply both sides by y

y sin30° = 17 ( divide both sides by sin30° )

y = \frac{17}{\frac{1}{2} } = 34

tan30° = \frac{opposite}{adjacent} = \frac{17}{x}

multiply both sides by x

x tan30° = 17 ( divide both sides by tan30° )

x = \frac{17}{\frac{1}{\sqrt{3} } } = 17\sqrt{3}

What is the image point of (4, -6) after a translation right 5 units and<br> up 4 units?
Ivan

Answer:

Coordinate point of the image is (9, -2)

Step-by-step explanation:

In the coordinate point (4, -6);

=> x-value = 4

=> y-value = -6

We know that the translation of;

=> 5 units right would add 5 to the x-value

  • <em>(x) + 5</em> = (4) + 5
  • 9 <= This is the x-value of the image being created by the translation.

=> 4 units up would add 4 to the y-value

  • <em>(y) + 4</em> = (-6) + 4
  • -2 <= This is the y-value of the image being created by the translation.

Therefore the answer; (x, y) => (9, -2)

Hope this helps!
