Answer:

  6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)

Step-by-step explanation:

A suitable calculator can find the value of this ratio for you.

  ((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)

Which ordered pair is a solution of the equation?<br> y=4x−7
vampirchik [111]

Answer:

Unknown

Step-by-step explanation:

Hi! so you didn't add the ordered pair options but I will do my best :) so if you see the ordered pair (0.7) that could definitely be a solution because using the slope intercept form equation you gave I know that's our y Intercept. the slope is 4/1 so moving up 4 and to the right 1 or down 4 and to the left 1 on a graph could show you more points! If you don't want to draw it you could use Desmos and just put this equation in or give me the ordered pairs and I will give you your answer!

hope this helps :)

Michael and Kathryn bowl together and their combined total score for one game was 425points. Michael’s score was 70 less than tw
In-s [12.5K]

Hey there!

Let us take Michael's score as ' x '

Let us take Kathryn's score as ' y '

Michael - 70 less than twice Kathryn's


x = 2y - 70

y = y

Add them, we get , 425

2y - 70 + y = 425

3y - 70 = 425

3y = 495

y = 495/3

y = 165

Kathryn's score = 165

Michael - 2 ( 165 ) - 70

= 260

Hope it helps!

(12x + 3) + (-7x+ 5)
mash [69]

Answer:

5x+8

Step-by-step explanation:

We have to distribute the + into -7x+5. So the equation will now be 12x+3-7x+5. Now let's organize it into terms. 12x-7x+3+5. Now let's simplify this. The final answer is 5x+8. That is the final answer!

Hope this helped!!! :D
