well, lateral area means only the area of the sides, namely just the four triangular faces.

\bf \textit{area of an equilateral triangle}\\\\ A=\cfrac{s^2\sqrt{3}}{4}~~ \begin{cases} s=sides\\ \cline{1-1} s=8 \end{cases}\implies A=\cfrac{8^2\sqrt{3}}{4}\implies A=16\sqrt{3} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{area of the 4 triangles}}{4(16\sqrt{3})}\implies 64\sqrt{3}

Solve using substitution for x and y 5x+y=16 <br> y=2-3x
valentina_108 [34]

Answer:

X = 7   Y = -19

Step-by-step explanation:

If you want to solve this equation by substitution then you have to put the second equation in, so it will look something like this

5x + 1(2-3x)=16

Apply distributive property to solve.

Once you find x, plug it in to find y

To double check your work, you can plug the coordinated values back in

-19 = 2 - 3(7)

-19 = 2-21

This is true, so our solution is correct.

Hope this helps :)

Find the domain and range of the relation and determine whether it is a function.
Anna [14]
The correct answer to this question is this "domain: x > 1; range: y > 0; Yes, it is a function."

Based from the graph, <span>it has a vertical asymptote at x = 1, so domain is x > 1 </span><span>and since it has horizontal asymptote at y=0, its range is y > 0. So this concludes us to have a domain of x > 1 and a range of y > 0.</span>

Wrie down the equation of the line that is parallel to 4x - 2y = 7 and passes through (9, -3) ​
EastWind [94]

Answer:

4x-2y =42 is the required equation

Step-by-step explanation:

given equation is,

4x-2y -7=0---------eqn1

parallel equation of given equation is

4x -2y+k =0-------eqn 2

now passing it through (9,-3), we get,

4×9 + 2×3 +k = 0

or,36+6+k =0

or,42+k =0

or, k= -42

putting the value of k in eqn2

4x-2y - 42=0

4x-2y = 42
