Add the real parts and the imaginary parts separately and divide each by 2


= (  \frac{ - 4 + 6}{2}  +   \frac{ - 2i + 8i}{2} )


= ( \frac{2}{2}  +  \frac{6i}{2} )


=(1+3i)

5x+8=3x-6 plz help me asap
Ray Of Light [21]

Answer:

x = -7

Step-by-step explanation:

5x+8=3x-6

Subtract 3x from each side

5x-3x+8=3x-3x-6

2x+8 = -6

Subtract 8 from each side

2x+8-8 = -6-8

2x = -14

Divide by 2

2x/2 = -14/2

x = -7

IT'S A TIME SENSITIVE EMERGENCY!!!
kap26 [50]

Complete question is missing, so i have attached it.

Answer:

Yes, they are all correct

Step-by-step explanation:

From the attached image, we see that the sign is showing;

Parking lot: ¾ miles

Summit: 1½ miles

Summit distance can also be expressed as an improper fraction = 3/2 miles

Now, since they started hiking from the park to the summit, it means that they had moved ¾ mile from the parking lot and had 3/2 miles left to get to the summit.

Thus, total distance from parking lot to summit = ¾ + 3/2 = 9/4 miles

Now, let's analyze each of their statements;

Mai said they are a third of their way there.

They had covered 3/4 mile and the total distance is 9/4 miles.

Thus, fraction of total distance covered is;

9/4 ÷ 3/4 = 1/3.

So, Mai is correct

Clare said they have to go twice as far as they had already gone.

They had covered 3/4 miles.

Therefore, twice this = 2 × 3/4 = 6/4 = 3/2 which is same as the sign distance left to the summit.

Thus, Clare is correct

Tyler said that the total hike is three times as long as what we have already gone.

They had gone 3/4 miles

3 times this = 3 × 3/4 = 9/4 miles.

This tallies with the total distance calculated earlier.

Thus, they are all correct

Round to the nearest hundredth please answer I really need it
iVinArrow [24]
<h3>Answer: 35.54 degrees</h3>

How I got this answer:

tan(angle) = opposite/adjacent

tan(A) = BC/AC

tan(A) = 5/7

A = arctan(5/7)  .... apply the inverse tangent, same as arctangent

A = 35.5376778 ... make sure your calculator is in degree mode

A = 35.54 .... rounding to two decimal places
