Keisha is correct since all the points in quadrant one are positive. If the coordinates are interchanged, the x coordinate and the y coordinate will still both be positive so they will remain in quadrant 1
The improper fraction -8/3 is equivalent
Answer:
x=−2, 2.6666
Step-by-step explanation:
Let's solve your equation step-by-step.
4=(1/2(2x+4+x))(x−2)
Step 1: Simplify both sides of the equation.
4=3/2 x2−x−4
Step 2: Subtract 3/2x^2-x-4 from both sides.
4−(3/2 x2−x−4)=
3/2 x2−x−4−(3/2 x2−x−4)
−3/2 x2 +x+8=0
For this equation: a=-1.5, b=1, c=8
−1.5x2+1x+8=0
Step 3: Use quadratic formula with a=-1.5, b=1, c=8.
x=−b±√b2−4ac
2a
x=−(1)±√(1)2−4(−1.5)(8)
2(−1.5)
x=−1±√49
−3
x=−2,2.66666666666666666666666666666
To Match
To isolate -1 we need to subtract 2m from both sides
2m - 1 = 3m (SUBTRACT 2m)
To isolate 1 we need to subtract m from both sides
2m = 1 + m (SUBTRACT m)
To isolate m we need to add 1 from both sides
m - 1 = 2 (ADD 1)
To isolate m we need to subtract 2 from both sides
2 + m = 3 (SUBTRACT 2)
To isolate m we need to add 2 from both sides
-2 + m = 1 (ADD 2)
To isolate m we need to subtract 1 from both sides
3 = 1 + m (SUBTRACT 1)
