Answer:

y=1+-2 then simplify

Step-by-step explanation:

9x+3y=3

first dicide so

$\frac{9x}{3} + \frac{3y}{3} = \frac{3}{3}$

2x+y=1

now move 2x to other side

so it would turn negative

put in point slope form-y=mx+b

y=1+-2×

If I rencently decreased my average number of products sold per week by 15% I now sell an average of 21.25 products per week. Pr

VladimirAG [237]

Alright, lets get started.

Suppose previously I was selling product per week = x

As per question, I have decreased my average number of product by 15 %

Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x

So, the new average product = x - 0.15 x = 0.85 x

As per given question, the new average product = 21.25

0.85 x = 21.25

Dividing by 0.85 in both sides

0.85 x / 0.85 = 21.25 / 0.85

x = 25

Hence it means, 25 products were selling previuosly. : Answer

Hope it will work :)

Grayson is flying a kite, holding his hands a distance of 2.75 feet above the ground and letting all the kite’s string play out.

sergiy2304 [10]

The position of the kite with the point directly beneath the kite at the same

level with the hand and the hand for a right triangle.

The height of the kite above the is approximately 66.314 feet.

Reasons:

The height of his hands above the ground, h = 2.75 feet

Angle of elevation of the string (above the horizontal), θ = 26°

Length of the string, l = 145 feet

Required:

The height of the kite above the ground.

Solution:

The height of the kite above the ground is given by trigonometric ratios as follows;

$\displaystyle Height \ of \ kite, \, k_h = \mathbf{h + l \times sin(\theta)}$

Therefore;

$\displaystyle Height \ of \ kite, \, k_h = 2.75 + 145 \times sin(26^{\circ}) \approx \mathbf{66.314}$

The height of the kite above the, $k_h$ ≈ 66.314 feet
