Answer:
2) y = x - 4
y = -x + 2
=> x - 4 = -x + 2
=> 2x = -6
=> x = -3
=> y = -3 - 4 = -7
3) y = 3x + 1
y = 5x - 3
=> 3x + 1 = 5x - 3
=> 2x = 4
=> x = 2
=> y = 3(2) + 1 = 7
4) 2x + y = 8 => y = -2x + 8
y = x - 7
=> -2x + 8 = x - 7
=> 3x = 15
=> x = 5
=> y = 5 - 7 = -2
The congruence of the 2 triangles can be proved, angle C is common , CD is common, CA = CB, THEN the 2 triangles are congruent, the 2 triangles are equal so AD = DB hence CD bisects AB.
AND just that a attitude does not divides a line into equal half's, in an obtuse angle triangle the altitude is outside, only the median can divide a line into 2 equal half's or a triangle
hope this helps if this did Pls like and have any doubts ask me in the comments section, feel free
Answer:
$375
Step-by-step explanation:
9 + 8 = 17
17 + 20 = 37
