Answer:
m= 8n-7/10
Step-by-step explanation:
n- 5/2 + 5/4 m= -27/8 + 2n
n- 5/2 + 5/4 m-n = -27/8 +2n-4
-5/2 +5 /4m=- 27/8 +n
- 5/2 + 5/4 m + 5/2 = - 27/8+n+ 5/2
5/4 m =n- 7/8
4. 5/4 m=4n -4 . 7/8
5m=4n- 7/2
5m/5 = 4n/5 - 7/2 /5
m= 8n-7/10

Answer:
y=8(x+1)²-2
Step-by-step explanation:
Completing the square is a method of factorising. x²+bx+c=0 becomes x²+bx+(
b)²-(
b)²+c=0. This then gets converted to make an equation of (x+
b)²+(-(
b)²+c)=0.
Vertex form is y=a(x-h)²+k.
8x²+16x+6=0 must first be divided by 8 to 8(x²+2x+
)=0 (as there cannot be a coefficient for x²).
This will become 8(x²+2x+
²-
²+
)=0.
From there, using the method above, we can convert it to 8[(x+1)²-1+
]=0.
Solving this gets 8[(x+1)²-
]=0.
With 8 as a, 1 as -h, and 8×-
(-2) as k, we can input this into vertex format to get the result of y=8(x+1)²-2.
**This equation involves completing the square and vertex form, which you may wish to revise. I'm always happy to help!
Answer:
x=2, y= -1 (2,-1)
Step-by-step explanation:
4y=2-3x
11x+(2-3x)=18
8x+2=18
8x=16
x=2
22+4y=18
y=-1
