You have to find the discriminat b^2 -4ac
If it is > 0, the function has two real solutions
if it is = 0, the function has one real solution
if it is <0, the function has no real solution
6^2 - 4(7)(3) = 36 - 84 = - 48
Answer c. no solution
Answer:
See the below part
Step-by-step explanation:
1)
8 - 2x = 5 - 4x
=> 8 - 5 = -4x + 2x
=> 3 = -2x
=> 3/-2 = x
=> -3/2 = x
2)
4 + 3x = 2 - 2x
=> 4 - 2 = -2x - 3x
=> -2 = -5x
=> 2 = 5x
=> 2/5 = x
3)
2(x - 1) + 2(3x - 1) = 0
=> 2x - 2 + 6x - 2 = 0
=> 8x - 4 = 0
=> 8x = 4
=> x = 4/8
=> x = 1/2
Answer:
103.96
Step-by-step explanation:
The answer is 939.44 - 835. 48
we can do like: 939.44 - 835. 48 = 103.96 ( 938 -835 = 103 and 144 - 48 = 96).
Have a good day
