Triangles are congruent when all corresponding sides and interior angles are congruent. The triangles will have the same

'y=x+13, xy=30' ????

Art [367]

This is a simultaneous equation. its saying there are two numbers (x and y) that satisfy both equations. Rearrange the 2nd equation to get x=30/y and substitute this into the first equation to get y=(30/y) +13. solve this for y and then you can solve for x.

Use the given information to write an equation of a line that contains a slope of 4 and passes through (-2, -6). Write your answ

Svetach [21]

$(\stackrel{x_1}{-2}~,~\stackrel{y_1}{-6})\qquad \qquad \stackrel{slope}{m}\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-6)}=\stackrel{m}{4}(x-\stackrel{x_1}{(-2)})\implies y+6=4(x+2)$

$y+6=4x+8\implies y=4x+2\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

Si una porcion es de 228 gramos cuantos gramos contiene el producto

ehidna [41]

Answer: 456 gramos.

Step-by-step explanation:

Con una busqueda online, encontré que la imagen relacionada con este problema es la que se ve abajo.

En ella podemos ver que el envase del producto trae dos porciones.

Entonces, si una porción tiene 228 gramos, dos porciones son:

2*228 g = 456 gramos.

Y el envase tiene dos porciones, entonces el envase tiene 456 gramos.

How do I do this, it is for geometry (ignore the answer it was a guess) thank you so much.

Answer:

AC is about 41. 095 miles long.

Step-by-step explanation:

You can use the Law of Cosines to solve this: c^2 = a^2 + b^2 – 2ab cos(C)

Substitute in your values, and you're good to go!

c^2=16^2+28^2-2(16)(28)(cos(117))

c^2 = 256 + 784 - 896(cos(117))

c = sqrt(1040 - 896(cos(117)))

c is about 41. 095 miles long.
