Answer:
Properties of rhombus
. all the properties of a parallelogram( apply the ones that matter hair are parallel sides opposite angles congruent and consecutive angles are supplementary)
. all sides are congruent by definition
. the diagonals bisect the angles
. the diagonals are perpendicular bisectors of each other
Properties of rectangle
. all the properties of parallelogram apply (the ones that matter hair are parallel sides, opposite sides are congruent, and diagonals bisect each other)
. all angles are right angles by definition
. the diagonals are congruent
Properties of square
. all the properties of a rhombus apply( the ones that matter have a parallel sides diagonals are perpendicular bisector of each other and diagonals bisect the angles)
. All the properties of rectangle apply (the only one that matter where is diagonals are congruent)
. All angles are right angles by definition

Step-by-step explanation:
STEP 1
Calculate the slope from 2 points.
STEP 2
Substitute either point into the equation. You can use either (3,7) or (5,11)
STEP 3
Solve for b, which is the y-intercept of the line.
STEP 4
Substitute b, -1, into the equation from step 2.
Answer:
Step-by-step explanation:
To find the number of inches, divide miles by 9.5.
__
a) 24 miles = (24 mi)×(1 in)/(9.5 mi) = (24/9.5) in ≈ 2.526 in
__
b) 24 miles + 16 miles = 40 miles = (40 mi)×(1 in)/(9.5 mi) = 40/9.5 in ≈ 4.211 in

Comment on units conversion
I find it convenient to work units conversion problems by writing a fraction that is equal to 1 and multiplying by that to change units. My fraction has the "to" units in the numerator, and the "from" units in the denominator. That way, the unwanted units cancel when the multiplication is carried out.
The fraction is equal to 1 because the measurement in the numerator is equal to the measurement in the denominator.
__
Some folks prefer proportions. If you do it that way, be sure "like" is matched with "like".
map inches/ground miles = 1/9.5 = x/24
route inches/scale inches = route miles/scale miles = x/1 = 24/9.5
Answer:
x = 7.75 y = -0.125
Step-by-step explanation:
3x + 2y = 23 1/2x - y = 4
2(1/2x - y) = (4)2 1x - 2y = 8
3x + 2y = 23
+ 1x - 2y = 8
4x = 31
x = 7.75
3(7.75) + 2y = 23
23.25 + 2y = 23
2y = -0.25
y = -0.125
