Answer:
The solution of the given system is (2,0)
Step-by-step explanation:
Here, the given system of equations is:
x + y = 2 .............. (1)
........ (2)
Now from (1) x = 2 - y
Substitute this value of x = 2- y in (2) ,we get:
⇒ y = 0 or, y = -1
Now, if y = 0, x = 2
and if x= -1, y = 2-(-1) = 2+1 = 3, or y = 3
But (x = -1 , y = 3 )is NOT a solution of (2).
Hence, the solution of the given system is (2,0)
Answer: It depends on you if it seems easier for you, you should try both and see which one works better for you.
Answer:
<em>f</em>(x) = (x + 4)² - 13
Step-by-step explanation:
You will have to "complete the square [½B]²" to figure this out. Here is how you would set it up:
(x + 4)² → x² + 8x + 16
x² + 8x + 16 - 13 → x² + 8x + 3 [TA DA!]
We know that our vertex formula is correct. Additionally, that <em>-</em><em>h</em><em> </em>gives you the OPPOSITE terms of what they really are, and <em>k</em><em> </em>gives you the EXACT terms of what they really are. Therefore, your vertex is [-4, -13].

Answer:
174 (if you can round)
Step-by-step explanation:
26% of 174 is 45.24
if you round to down then you get 45
hope this helps
Answer:
2
Step-by-step explanation:
If the value of the discriminant is positive, there are two real solutions for x, meaning the graph of the solution has two distinct x-intercepts
Here 25 is positive discriminant, hence the function will have 2 x - intercepts
