Answer:

One solution:(1,2)

Step-by-step explanation:

y = x + 1

/Plug this in for variable y in equation [2]

-2x - (x +1) = -4

-3x = -3

Solve equation [2] for the variable x

3x = 3

x = 1

By now we know this much :

x = 1

y = x+1

Use the x value to solve for y

y = (1)+1 = 2

Hope this helps :D please mark brainliest if correct

Rhombus ADEF is inscribed in △ABC such that the vertices D, E, and F lie on the sides AB , BC , and AC respectively. Find the si

Oksanka [162]

<h3>Answer:</h3>

3 11/15 cm

<h3>Step-by-step explanation:</h3>

AE is the angle bisector of ∠A, so divides the sides of the triangle into a proportion:

... BE:CE = BA:CA = 7:8

Then ...

... BE:BC = 7 : (7+8) = 7:15

ΔDBE ~ ΔABC, so DE = 7/15 × AC

... DE = 7/15 × 8 cm = (56/15) cm

... DE = 3 11/15 cm
