Three more than twice a number x is 15. Determine the value of x.
GuDViN [60]

Answer:

Pretty sure the answer would be x=6

Step-by-step explanation:

The number (x) in: "3 more than twice a number is 15" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15

Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 3 = 15

2x + 3 - 3 = 15 - 3

2x = 12

2x/2 = 12/2

x = 6

Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. x = cos(θ) + sin(4θ
dybincka [34]

The line tangent to the curve at (x(0),y(0)) has slope

\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{\theta=0}=\dfrac{\mathrm dy}{\mathrm d\theta}\dfrac{\mathrm d\theta}{\mathrm dx}\bigg|_{\theta=0}=\dfrac{\cos\theta-4\sin4\theta}{-\sin\theta+4\cos4\theta}\bigg|_{\theta=0}=\dfrac14

Then the tangent line has equation

y-y(0)=\dfrac14(x-x(0))

y-1=\dfrac14(x-1)

\boxed{y=\dfrac{x+3}4}
