Simplify -8+6i/4-2i

Answers

Answer 1

Answer:

Answer:

-1.1+0.4i

Step-by-step explanation:

Multiply the numerator and the denominator by $4+2i:$

$(-8+6i)/(4-2i)\cdot (4+2i)/(4+2i)=(-32-16i+24i+12i^2)/(4^2-(2i)^2)\ \ [\text{use formula }a^2-b^2=(a-b)(a+b)]\n \n=(-32+8i-12)/(16-4i^2)\ \ [\text{remember }i^2=-1]\n \n=(-44+8i)/(16+4)\n \n=(-44+8i)/(20)\n \n=-(11)/(10)+(4)/(10)i\n \n=-1.1+0.4i$

Solve the equation: 2 * x-3 = 25, x =? (digit answer):

Answers

is your answer for x

2(x) - 3 = 25

Note the equal sign, what you do to one side you do to the other. Do the opposite of PEMDAS.

First, add 3 to both sides

2x - 3 (+3) = 25 (+3)

2x = 25 + 3

2x = 28

Isolate the x. Divide 2 from both sides

(2x)/2 = (28)/2

x = 28/2

x = 14

is your answer for x

Final answer:

The solution to the equation 2 * x - 3 = 25 is x = 14. This is achieved by first adding 3 to both sides of the equation to isolate the term with x, and then dividing both sides of the equation by 2.

Explanation:

To solve the equation 2 * x - 3 = 25 for x, you should start by adding 3 to both sides of the equation to isolate the term with x. This will give us 2 * x = 28. Then, you divide both sides of the equation by 2 to solve for x. This results in x = 14. So, the solution to the equation 2 * x - 3 = 25 is x = 14.

Simplify 4/1/2 divide 1/1/5

Answers

Answer:

Step-by-step explanation:

4/1/2 divide 1/1/5

(4/1/2) / (1/1/5)

= 40

Answer: $3(3)/(4)$

Step-by-step explanation:

Convert 4&1/2ths to improper fraction. Use this rule: a&b/c=ac+b/c

$((4*2+1)/(2) )/(1(1)/(5) ) \n\n((9)/(2) )/(1(1)/(5))$

Use a&b/c=ac+b/c again to make 1&1/5ths and improper fraction.

$((9)/(2))/((1*5+1)/(5)) =((9)/(2) )/((6)/(5) )$ now you need to invert and multiply

$(9)/(2)* (5)/(6)=(9*5)/(2*6) =(45)/(12) =(15)/(4) = 3(3)/(4)$

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

In the figure, a ‖ b and m∠1 = 34°.
What is m∠7?
__ °

Answers

If angle 1 is equal to 34 degrees, angle will be 34 too, because 1 and 3 are oppostite angles. And 3 and 5 are alternate interior angles, meaning they are alson equal so, angle 5 = 34. And finally , angle 5 and angle 7 are opposite angles so they are equal too, angle 7 = 34
