What is the equation to this problem?

allsm [11]

Answer:

x = 13 1/2 or 27/2

Step-by-step explanation:

1st Add 2 to both sides: 2/3x-2+2=7+2

2nd Simplify: 2/3x = 9

3rd Multiply both sides by 3: 3*2/3x=9*3

4th Simplify: 2x=27

5th Divide both sides by 2: 2x÷2=27÷2

6th Simplify: x = 13 1/2 or 27/2

In the right triangle shown, AC = BCAC=BCA, C, equals, B, C and AB = 6AB=6A, B, equals, 6.

alexandr402 [8]

Answer:

$|AC|=|BC|=3\sqrt{2}$

Step-by-step explanation:

In a right triangle, the hypotenuse is always the longest side. Since AC = BC, AB is the Hypotenuse.

Using Pythagoras theorem

$|AB|=6,|AC|=|BC|\\|AB|^2=|AC|^2+|BC|^2\\6^2=2|AC|^2\\36=2|AC|^2\\18=|AC|^2\\|AC|=\sqrt{18}=3\sqrt{2} \\Therefore, |AC|=|BC|=3\sqrt{2}$

Find an equation of the plane tangent to the following surface at the given point.z equals tangent Superscript negative 1 Baseli

Sergeeva-Olga [200]

Let f(x, y, z) = z - arctan(x y). Compute the gradient of f at the point (0, 3, 0):

∇ f(x, y, z) = (-y / (1 + x²y²), -x / (1 + x²y²), 1)

∇ f (0, 3, 0) = (-3, 0, 1)

This vector is orthogonal to the surface z = f(x, y). Then the equation of the tangent plane is

∇ f (0, 3, 0) • (x, y - 3, z) = 0

(-3, 0, 1) • (x, y - 3, z) = 0

-3x + z = 0

z = 3x
