Answer:
Quadrilateral ABCD is a <u>parallelogram</u>
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a <u>kite</u>
Step-by-step explanation:
without solving, im guessing that quad ABCD is a paralellogram (//gram)
lets test this theory
see if the slope of AB and CD, and BC and AD is the same
slope AB and CD
AB:
-7--4/11-9
=-3/2
CD:
-1--4/11-13
=3/-2
=-3/2
slope is the same
slope BC and AD
BC:
-4--1/9-11
=-3/-2
=3/2
AD:
-7--4/11-13
=-3/-2
=3/2
slope is same
because 2 pairs // sides ---> //gram
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite
hope this helps!
please mark brainliest thank you !
Answer:
Step-by-step explanation:
Let c represent Chanda's age now. In six years, the Sokhem's age will be 2c. At that time, the sum of their ages is ...
(c+6) +2c = 60
3c = 54 . . . . . . . . subtract 6, collect terms
c = 18 . . . . . . . . . . divide by 3
Chanda is 18, Sokhem is 30.
_____
<em>Check</em>
In 6 years Chanda will be 24, Sokhem will be 36. The sum of their ages then will be 24+36 = 60. Since Chanda is 18 now, Sokhem's age then will be 2 times Chanda's age now.
Answer:
Pete worked for 4 hours.
Step-by-step explanation:
If you subtract his tips from his overall total (50-16) you get 34. Now you divide what's left of his total by his hourly wage (34/8.5) which gets you 4.

Answer:
Perpendicular.
Step-by-step explanation:
For parallel lines slopes are equal.
The slope of y = x + 3 is 1 and the slope of y = -x - 5 is -1 so they are not parallel.
For perpendicular lines m1*m2 = -1 (where m1 and m2 are the slopes).
So these 2 lines are perpendicular.
