Dafna1 [17]3 years ago
3 0

Answer:

1+14i

Step-by-step explanation:

- remove unnecessary parentheses (-3 + 8i)  -(-4 - 6i) = -3+8i - (-4-6i)

- when there is a - in front of an expression in parentheses, change the sign of each term in the expression -3+8i+4+6i

- calculate the sum

(-3+4=1) = 1+8i+6i

- collect like terms

(8i+6i=14i) = 1+14i

SOLUTION: 1+14i

For all values of x less than 7.5 the above inequality satisfies , i.e x

<u>Step-by-step explanation:</u>

Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥ and ≠.

7 \textgreater x reads as '7 is greater than x' (or ' x is less than 7', reading from right to left).

x \leq -4 reads as ' x is less than or equal to -4' (or '-4 is greater than or equal to x', reading from right to left).

x \neq 5  reads as ‘ x is not equal to 5.

Here , we have

\begin{aligned}&2 x       { Dividing both sides by 2. }

∴ For all values of x less than 7.5 the above inequality satisfies.

How do you convert units within a measurement system?
Anit [1.1K]
To convert among units in the metric system, identify the unit that you have, the unit that you want to convert to, and then count the number of units between them. If you are going from a larger unit to a smaller unit, you multiply by 10 successively.
