Answer:
x=34
Step-by-step explanation:
90-22=68
68÷2=34
You plug in the given value for x.
F(-4)=(-4)2-4
F(-4)=-8-4
F(-4)=-12
F(0)=(0)2-4
F(0)=0-4
F(0)=-4
F(3)=(3)2-4
F(3)=6-4
F(3)=2
Answer:
Ellen invested $60 and Bob invested $140
Step-by-step explanation:
let the two amounts invested by 3x and 7x
(notice 3x : 7x = 3 : 7 )
then 3x + 7x = 200
10x = 200
x = 20
then 3x = 3(20) = 60
and 7x = 7(20) = 140
60+140=200
In order to name the coordinates, you read the X axis first and then the Y axis. So A would be (-4, 4). B would be (-4, 6). C would be (2, 4).
They are not congruent because each angle is a different measure.
Hope this helped! :)
