Between the 4 and the 7 is it a multiplication or an X?
If the multiplication sign, this is the solution
You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
x = 1 because -7(3x + 4) must be -49 so 3x + 4 must me 7 so x = 1
Answer:
2/10 or 1/2 = .5 you would divide 2 by 2 and 10 divided by 2 (whatever you multiply or divide by on the top you must do on the bottom)
2/10=.50
3/100=.03 (divide 3 by 10=.0
V(x) = (2x - 3)/(5x + 4)
The domain is all Real numbers except x = -4/5, because if x = -4/5 the denominator would be zero and you cannot divide by zero.
{x | x ∈ R, x ≠ -4/5}
w(x) = (5x + 4)/(2x - 3)
similarly, x ≠ 3/2
so, {x| x ∈ R, x ≠ 3/2}
