Answer:
0.5
Step-by-step explanation:
To find the value of t, we need to get t by itself.
25t=12.5
25 is being multiplied by t. To undo this, divide both sides by 25, since division is the opposite of multiplication. This will cancel out the 25, and leave t by itself.
25t/25=12.5/25
t=0.5
So, the value of t that makes the equation true is 0.5
2x²-6x+8=0
x²-3x+4=0
D=b²-4ac=9-16=-7
x=(3+/-i√7)/2
correct answer is the last one
Answer:
x= 0, 1/2, and 3
Step-by-step explanation:
x=0
2x-1=0----> 2x=1 -------> x= 1/2
x-3=0 -----> x=3
Hope this helps
