Answer:
6-11i
Step-by-step explanation:
(2 + 7i) - (6 + 8i) + (10 - 10i)
Distribute the minus sign
(2 + 7i) - 6 - 8i + (10 - 10i)
Combine like terms
2-6 +10 +7i-8i-10i
6 -11i
Answer:
<2 = 129°
Step-by-step explanation:
if I || m then 5x+12 =m<2 and m<2 + 2x + 14 = 180°
2x + 14 + 5x + 12 = 7x + 26 =180°
7x = 154 ➡x = 21°
m <2 = 5×21 + 14
Answer:
Step-by-step explanation:
Equation: y=mx+b
m is the gradient while b is the y-intercept
Let's first find the slope (also known as the gradient) by choosing two points.
The formula to find the slope is change in y divided by change in x.
So two points are: (-2,0) and (0,5)
Change in y: 5-0 (we use the y-coordinates)
Change in x: 0--2 (0+2) (we use the x-coordinates)
So: 5-0= 5 and 0+2= 2 which means 5 divided by 2
Slope= 5 over two
To find the y-intercept we need to see where the line crosses the y-axis which would be at (0,5)
So: y-intercept is 5 as that's where the line crosses the y-axis.
Equation now: y= 5 over 2x +5
No they are not similar.
8/16 <> 12/12 or 8/12 <> 12/16
