Answer:

When subtracts fractions with the same denominator, you only have to subtract the numerator.

5/9-3/9=

The denominators are the same, you just have to subtract the denominator. So in this case, you would only need to subtract 5-3. Therefore the answer would be 2/9. (Simplify if needed.)

Answer: Option A

$x=\frac{3+i}{2}$ or $x=\frac{3-i}{2}$

Step-by-step explanation:

Use the quadratic formula to find the zeros of the function.

For a function of the form

$ax ^ 2 + bx + c = 0$

The quadratic formula is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

In this case the function is:

$2x^2-6x+5=0$

$a=2\\b=-6\\c=5$

Then using the quadratic formula we have that:

$x=\frac{-(-6)\±\sqrt{(-6)^2-4(2)(5)}}{2(2)}$

$x=\frac{6\±\sqrt{36-40}}{4}$

$x=\frac{6\±\sqrt{-4}}{4}$

Remember that $\sqrt{-1}=i$

$x=\frac{6\±\sqrt{4}*\sqrt{-1}}{4}$

$x=\frac{6\±\sqrt{4}i}{4}$

$x=\frac{6\±2i}{4}$

$x=\frac{3\±i}{2}$

$x=\frac{3+i}{2}$ or $x=\frac{3-i}{2}$

kerry is comparing the number 9.207 and 9.210. what is the least place value she needs to compare to decide which number is grea

andrew11 [14]

The number 9.210 is greater. The least place value is the 0 (Zero) and the 1 (One). This is because the 9 (Nine) and the 2 (Two) in 9.207 and 9.210 is the same numbers. There so, you can't compare those 2 (Two) numbers.
