Answer:
JK≅MN, KL≅NO and ∠K≅∠N
Step-by-step explanation:
we know that
A Reflection is a transformation that doesn't change the size or shape of the figure
so
Triangle JKL and triangle MNO are congruent
The corresponding sides and the corresponding angles are congruent
therefore
JK≅MN, KL≅NO,JL≅MO
and
∠J≅∠M, ∠K≅∠N,∠L≅∠O
(x1,y1) = (-2,7)
m = -5
(x,y) = (a,2)
Forming the equation,
(y-y1) = m(x-x1)
y - 7 = -5[x - (-2)]
y - 7 = -5x - 10
y + 5x = -3
Putting the values of (x,y) we get,
2 + 5a = -3
5a = -5
a = -1
Answer:
Step-by-step explanation:
175-(8+45÷3)x7 s
start with what's inside the parenthesis
(8+45÷3) ⇒ (8+15) ⇒(23)
175-(23)x7
then do multiplication
23x7
161
175-161
14
final answer is 14
Answer:
13
Step-by-step explanation:
Set Susan's present age as x, her age from 3 years ago as x-3, and her age in three years as 2(x-3)
Since her age in seven years = 2 times as old as she way 3 years ago, set up the equation:
x+7 = 2(x-3)
x+7 = 2x-6
x = 13
