Step-by-step explanation:

From the question we are told that:

Slant Height of Kite h_s=175

Angle \theta=40 \textdegree

Since Emma,The Kite and Andrew forms a right angle triangle

2x+2y=8 in function form step by step please?
nasty-shy [4]
You could get two different functions out of this:

<u>2x + 2y = 8</u>

1). <u> 'y' as a function of 'x'</u>

Subtract  2x  from each side:  2y  = -2x + 8

Divide each side by  2 :         <em> y  =  -x + 4</em>


2). <u> 'x' as a function of 'y' :</u>

Subtract  2y  from each side:    2x  =  -2y + 8

Divide each side by  2 :        <em>  x  =  -y + 4</em>

Those two functions look the same, but that's just because the original
equation given in the problem was so symmetrical.  In general, they're
not the same function.

The perimeter of the trapezoid-shaped window frame is 23.59 feet. Write and solve an equation to find the unknown side length x
krok68 [10]

Answer:

5.62 + 3.65 + 5.62 + x = 23.59

x = 8.7 ft

Step-by-step explanation:

Perimeter of the trapezoid-shaped window = sum of all the sides of the window frame

Thus, the equation to find the unknown side length, x, would be:

✔️5.62 + 3.65 + 5.62 + x = 23.59

Solve for x

14.89 + x = 23.59

Subtract 14.89 from each side

14.89 + x - 14.89 = 23.59 - 14.89

✔️x = 8.7 ft

vagabundo [1.1K]

Answer:

y=2x+3

Step-by-step explanation:

The coefficient has to be 2, since the graph has a slope of 2, and the constant has to be 3 because the y- intercept is 3.

y=2x+3
