Answer:
None of those answers are correct
Step-by-step explanation:
There are no real solutions
Let's solve your equation step-by-step.
2+2x−3
2x+3
=
3x+4
x+2
Step 1: Cross-multiply.
2+2x−3
2x+3
=
3x+4
x+2
(2+2x−3)*(x+2)=(3x+4)*(2x+3)
2x2+3x−2=6x2+17x+12
Step 2: Subtract 6x^2+17x+12 from both sides.
2x2+3x−2−(6x2+17x+12)=6x2+17x+12−(6x2+17x+12)
−4x2−14x−14=0
For this equation: a=-4, b=-14, c=-14
−4x2+−14x+−14=0
Step 3: Use quadratic formula with a=-4, b=-14, c=-14.
x=
−b±√b2−4ac
2a
x=
−(−14)±√(−14)2−4(−4)(−14)
2(−4)
x=
14±√−28
−8
Answer:
No real solutions.
Answer:
8 miles per hour.
Step-by-step explanation:
24miles in 4 hours = 24/4=6 miles per hour.
24 miles in 3 hours = 24/3=8 miles per hour. The boat going with the current of the river is traveling at 8 miles per hour.
3x-5y+6z=4
-3x+9y-15z=15
4y-9z=19
-2x+6y-10z=10
2x- 4y+ z= 13
2y-9z=23
4y-9z=19
-2y+9z=-23
2y=-4
y=-2
3x+10+6z=4
x - 6 +5z=-11
3x+6z=-6
x +5z=-5
3x+6z=-6
-3x-15z=33
-9z=27
z=-3
x+6-15=-5
x-9=-5
x=4
