I have no idea but I need points
Answer:
8a-4n+14?
Step-by-step explanation:
<span>sin(a+bi) = sina·coshb + i·cosa·sinh<span>b
sin(2+3i) = sin2·cosh3 + i·cos2·sinh3
so
u = sin2cosh3
v = cos2sinh3
</span></span>
Answer:
(-3, -2)
Step-by-step explanation:
1. you moved right 7 units
2. you moved left 4 units
3. you ended up in (0, -2)
if you reverse it,
1. you start in (0, -2)
2. you move right 4 units (4, -2)
3. you move left 7 units (-3, -2)
Answer:
Madeline: y=1x+9
Issac: y=2x+1
x=8, y=17
Step-by-step explanation:
<u><em>Solving for X:</em></u>
<u>Multiply Issac's by -1:</u>
y= 1x+ 9
-y=-2x-1
<u>Combine:</u>
0=-x+8
<u>Add x to both sides:</u>
<em><u>x=8</u></em>
<em><u>Solving for Y:</u></em>
<em>Since we already have x, we only need to input the x value into one of the formulas:</em>
y=1(8)+9
<u>Simplify parenthesis with multiplication:</u>
y=8+9
<u>Add:</u>
<u><em>y=17</em></u>
If you feel unsure, check your work with both equations:
(17)=2(8)+1
17=16+1
17=17=Good
(17)=1(8)+9
17=8+9
17=17=Good
Please give a brainliest and a thx ;)
I hope this helps u :)
