Answer:
(- 7, - 3) and (7, - 3)
Step-by-step explanation:
The best way to do this is to sketch the graph...when dealing with reflection in the y axis, the value for y remains the same and the value for x becomes negative if it was positive or becomes positive if it was negative
Answer:
y=-15
Step-by-step explanation:
Answer:
2x+1
Step-by-step explanation:
(4-2x), (-7-3x),(11x+6)
Add the three expressions
(4-2x)+ (-7-3x)+(11x+6)
Combine like terms
-2x-3x+11x+4-7+6
6x+3
Divide by the number of expressions which was 3
(6x+3)/3
2x+1
The average is 2x+1
Answer: Congruent
Step-by-step explanation:
Line BC is reflexive to itself
AB is congruent to CD, and that's given
Line AC is congruent to BC, using these prior proofs
Angle EDC and Angle FAB are congruent, and that's a given.
You can conclude that they are congruent by AAS
Answer:
The equation of the line is 7 x +5 y = 15.
Step-by-step explanation:
Here the given points are ( 5, -4) & ( -10, 17) -
Equation of a line whose points are given such that
(
) & (
)-
y -
=
( x -
)
i.e. <em>y - (-4)=
( x- 5)</em>
<em> y + 4 =
( x - 5)</em>
<em> y + 4 =
( x - 5 )</em>
<em> ( y + 4) =
( x - 5)</em>
<em> 5 (y + 4 ) = - 7 (x - 5 )</em>
<em> 5 y + 20 = -7 x + 35</em>
<em> 7 x + 5 y = 15</em>
Hence the equation of the required line whose passes trough the points ( 5, -4) & ( -10, 17) is 7 x + 5 y = 15.
