Answer:
180°
Step-by-step explanation:
A parallelogram has rotational symmetry of degree 2. That is, it maps to itself when rotated through angles that are multiples of 360°/2 = 180°.
The figure should be rotated 180 degrees.
Answer:
x cannot equal -4 (the last option)
Step-by-step explanation:
From the line, you can see x equals every number except -4 where there's an open circle, meaning that x cannot equal 4
Hello,
Answer A (graph most left)
Intersection is (10/3,-11/3)
y=-2x+3
y=-2-x/2
so -2x+3=-2-x/2
==>3x/2=5 ==>x=10/3
and y=-2*10/3+3=-11/3
Answer:
<em>k = - 7.5 </em>
Step-by-step explanation:
Slope "m" of a line through points
(
,
)
(
,
)
is m =
Slopes of perpendicular lines are opposite reciprocal:
= - 1
~~~~~~~~~~~~~~~
The slope of a line through points (0, 7) and (2, 10)
=
=
Slope of perpendicular line through points (3, 5) and (k, 12) is
=
or
=
=
2(k - 3) = - 21
k - 3 = - 10.5
<em>k = - 7.5</em>
Recall the formula for determining the interest using simple interest

Convert the rate into decimal form by dividing by 100%

Substitute the following values
P = $1300, r = 0.07, t = 6/12 (12 months in a year, only 6 months has passed)

Therefore, Margo will pay back $45.50 in interest.
