11x -7y= -14 (1)
x -2y= -4 (2)
Multiply (2) by 11, we have:
11x -22y= -44 (3)
Take (1)-(3), we have:
(11x-11x)+ (-7y-(-22y))= -14-(-44)
⇒ -7y+22y= -14+44
⇒ 15y= 30
⇒ y= 30/15
⇒ y= 2
x= -4+ 2y= -4+ 2*2= 0
The final answer is x=0, y=2~
Answer:
The function f(x)=1−(x+1)
Has 3 critical points x intercept, y intercept
has a critical point and local maximum at c=+1
It would have 3 critical points if the graph showed −2 also as 2 intercepts or curve.
The derivative does not exist when 0 was worked out.
Step-by-step explanation:
Answer:
False! However all equilateral triangles are acute
Hello,
Alicia borrowed $15,000
At 8% for 6 years
To get the % for 1 year
First multiply 15,000 by 8% (On a calculator would be easier)
You get 1,200
Now since she borrowed the money for 6 years, multiply 1,200 and 6
You get $7,200
So now, you add the $15,000 and $7,200
So Alicia has to pay $22,200 at the end of 6 years
Hope this helps

Answer:
28.4 degrees
Step-by-step explanation:
In the diagram attached
Height of the cliff, AB=54 m
Distance of the raft to the base of the cliff, AC=100m
We want to determine the angle of depression from the top of the cliff to the raft. This is angle OBA.
The angle of depression from the top of the cliff to the raft is 28.4 degrees correct to the nearest tenth.
