Answer:
Final answer as a coordinate point (x,y) = (9, -6)
Step-by-step explanation:
2x + 3y =0 ..............................(1)
8x + 9y = 18 ...........................(2)
from equation (1)
3y = -2x
y = -2/3 x
substitute for y in equation 2
8x + 9( -2/3 x) = 18
8x - 6x = 18
2x = 18
x = 18/2
x = 9
substitute for x in equation (1)
2(9) + 3y = 0
18 + 3y = 0
3y = -18
y = -18/3
y = -6

The answer you are searching for is .9
4x^2+16x+14=0
I just transfered the given equation to the other side..that must be in a standard form where ax^2+bx+c=0
9^3= 729, 729 x 4=2916, 2916/3=972, 972 x 3.14 =3052.08
When you subtract flip the signs of the second set.
2x^2+5-4x+3
Now combine like terms
2x^2-4x+8
Final answer: B
