Answer:11/84
Step-by-step explanation:
Answer:
x=-1, y=5. (-1, 5).
Step-by-step explanation:
y=-2x+3
y=-7x-2
-------------
-2x+3=-7x-2
-2x-(-7x)+3=-2
-2x+7x+3=-2
5x+3=-2
5x=-2-3
5x=-5
x=-5/5
x=-1
y=-2(-1)+3=2+3=5
Answer:
AE = 7.5
Step-by-step explanation:
Since <BAC = 
, then;
<BAD = <DAE = <CAE = 
(complementary angles)
From ΔABC, applying the Pythagoras theorem to determine the length of side AC;
= 
+ 
= + 
100 = + 25
= 100 - 25
= 75
AC = 
Applying trigonometric function to ΔCAE,
Cos = 
AE = × Cos
= 7.5
Therefore, AE = 7.5
Answer:
no
Step-by-step explanation:
they are not like terms because the term 9x^2 is to the 2nd power which means that you are supposed to times the number by itself 2 times and 9x is not to the 2nd power so it stays the same.
