When you are adding or subtracting fractions with different denominators, you need to find a common denominator.
The LCD will be 11 x 14 which is 154.
So...
9/11 - 2/14 becomes 126/154 - 22/154.
126/154 - 22/154 = 104/154 = 52/77
answer: 52/77
Answer:
Step-by-step explanation:
x² -14x+50= 0
this equation has 2 solutions because is a quadratic
the solurions are imaginary roots because the discriminant is less then 0
b²-4ac = (-14)²-4*1*50 = 194-200= -6
to find the actual roots use the quadratic formula
I believe you do it this way.
You multiply the den. with the whole number and add the num.
2 x 8 + 1 = 17. This now becomes 17/8 because you keep the same den.
1 x 7 + 2 = 9. This now becomes 9/7.
Now subtract 17/8 - 9/7
This equals 8/1, or, 8.
The x-intercepts are (-3,0) and (11,0)
The answer is c. 10y and -9y
