Hey there! We will Combine Like Terns for this one.

= −2x + −6xy + −3y + 7x

= (−6xy) + (−2x + 7x) + (−3y)

=−6xy + 5x + −3y

Given:

The inequality is

-2x+2>3x-8

To find:

The solution of the given inequality.

Solution:

We have,

-2x+2>3x-8

Isolate the variables terms on the left side.

-2x-3x>-2-8

-5x>-10

Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.

\dfrac{-5x}{-5}

x

Therefore, the correct option is D.

Find the arc length s, of an arc with central angle θ=210∘ and radius r=5cm.
olga_2 [115]
The relationship between radius (r), angle (θ), and arc length (s) is given by
.. s = r*θ . . . . . . . . θ in radians
.. s = (5 cm)*(210π/180)
.. s = 35π/6 cm
.. s ≈ 18.33 cm

Answer:  approximately 311 feet

I rounded to the nearest whole number since the other given values are whole numbers. The more accurate value is roughly 310.825323188148 feet.

=========================================================

Explanation:

Refer to the diagram below. When using the 47 degree as the reference angle, we know that,

  • opposite side = x
  • hypotenuse = 325

We can say:

sin(angle) = opposite/hypotenuse

sin(47) = x/425

425*sin(47) = x

x = 425*sin(47)

x = 310.825323188148

x = 311

The kite is approximately 311 feet off the ground.
