I believe the answer is B. 16.
2y=-x+9
6y=3(-x+9)
3x-3(-x+9)=-15
3x-(-3x+27)=-15
3x+3x-27=-15
6x=-15+27
6x=12
x=2
2y=-2+9
2y=7
y=7/2
Answer is (2 ; 7/2)
With the given equation, you have to determine the defined range.
Simplify the equation using cross-multiply.
W^2=4(2w-3)
Move the expression to the left side and change its sign.
w^2-4(2w-3)=0
Next, Distribute "-4" through the parenthesis
w^2-8w+12=0
Solve by using the quadratic equation. "x= +- Sqr (b)^2-4(a)(c) / 2(a)"
-(-8)+-Sqr (-8)^2-4(1)(12) / 2(1)
solve the equation
w=8 +- Sqr of 16
You got to separate the equation into two other equations and simplify it.
w= 8+4/2 +6
w=8-4/2=2
The correct answer is 6 and 2.
You first put a 1 under the 2
than you give them the same denominator(bottom number)
that is 18/9 and 4/9
Now add them together and get 22/9
now make that into a mixed-number by dividing 22 by 9 you get 2.44
So...4/9+2 =2.44
Hope this helps
