Answer: $66.50
Step-by-step explanation:
7% of $950 is $66.50
Usually, we use the number line to solve inequalities with the symbols,
<
,
≤
,
>
, and
≥
.(the second and last one was rather hard to find on my keyboard) In order to solve an inequality using the number line, though, just turn
the inequality sign to an equal sign. Then, solve the equation. Next step,
graph the point on the number line (remember to graph as an open circle if the
original inequality was <, or >). The number line should now be
divided into 2 regions, one to the left of the graphed point, and one to the
right of said point.
After that, pick a point in both regions and "test" it, check to see if it satisfies
the inequality when plugged in for the variable. If it does, draw a darker line from the point into that region, with an
arrow at the end. That is the solution to the equation: if one
point in the region satisfies the inequality, the entire region will
satisfy the inequality.
I had to check back in an old textbook to remember all of that. Sorry about the earlier answer. That was rather foolish to do so without actually understanding the question.

Answer:
0.28 -0.95i
Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator.
![\dfrac{4-3i}{4+3i}=\dfrac{(4-3i)(4-3i)}{(4+3i)(4-3i)}=\dfrac{7-24i}{25}=\boxed{0.28-0.96i}](https://tex.z-dn.net/?f=%5Cdfrac%7B4-3i%7D%7B4%2B3i%7D%3D%5Cdfrac%7B%284-3i%29%284-3i%29%7D%7B%284%2B3i%29%284-3i%29%7D%3D%5Cdfrac%7B7-24i%7D%7B25%7D%3D%5Cboxed%7B0.28-0.96i%7D)

If the original number is A∠β, the ratio is 1∠(2β), the square of the unit vector in the same direction as the original.
2000 grams because 1 kilogram is equal to 1000 grams. Therefore 2 kilograms is equal to 2000 grams
