Yes, ABD = CBD(?) because it is a reflection
Answer:
42
Step-by-step explanation:
Set the numbers in order from least to greatest, then find the one in the middle, which will be the median.
19, 23, 42, 56, 67
42 is in the middle, so it is the median.
Answer:
x - 2y = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given 2x + y = 3 ( subtract 2x from both sides )
y = - 2x + 3 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y =
x + c ← is the partial equation
To find c substitute (5, 4) into the partial equation
4 =
+ c ⇒ c = 
y =
x +
← in slope- intercept form
Multiply through by 2
2y = x + 3 ( subtract 2y from both sides )
0 = x - 2y + 3 ( subtract 3 from both sides )
- 3 = x - 2y , that is
x - 2y = - 3 ← in standard form
