Multiply 2nd equaton by 4 and add to first
-9x+4y=8
<u>-12x-4y=16 +</u>
-21x+0y=24
-21x=24
divide both sides by -21
x=-24/21
x=-8/7
C is answer
Answer:
368/527
Step-by-step explanation:
Answer:
The vertex of the graph of f(x) = |x - 13| + 11 is (13, 11).
Step-by-step explanation:
There is something called absolute value in the given function. It means two equations will result from it.
When
the resultant equation is
- This will be the first equation
or
When
the resultant equation is
- This will be the second equation.
The intersection of these lines will give the vertex as found by solving both equations at the same time.
_________
Replacing the value of
for any one;
(first one)
(second one)
The vertex is (13, 11)
Check the angle. If it they are less than 90°<span> , so they will result in acute angles. </span>
The reciprocal of a number x is 1/x.
Let x = 1000
The reciprocal is 1/1000.
