Answer:
4 + 5i
Step-by-step explanation:
To calculate this you have to combine the like terms until they cannot be combined any further:
7 + 10i + 4 - 10i - (7 - 5i)
11 + 0i - 7 - 5i
7 & 4 are liked terms so add them together + subtract 10i and 10i
4 + 5i <--- Final answer
Hope this helps!
You're just simply multiplying them by 2 because the scale factor being applied is 2. So..
P' Q' = 4 cm
A' B' = 3 cm
M' N' = 6 cm
Answer:
Part 1: m = -7
Part 2: y = -7x -11
Part 3: 7x + y = -11
Step-by-step explanation:
Part 1
Select 2 points, in this case (-2, 3) and (-1, -4) and then use the slope formula
m = (y2 - y1) / (x2 - x1)
m = (-4 -3) / (-1 - -2) =
m = -7/1
m = -7
Part 2
Use the point-slope form equation to find the slope-intercept form
y - y1 = m(x - x1)
y - 3 = -7(x - -2)
y = -7(x +2) +3
y = -7x -14 +3
y = -7x -11
Part 3
Move the x and y to the same side of the equation
y = -7x -11
7x + y = -11
He can only pick 7 different groups because 2 times 7 is 14, and there are 15 people in all.
Hope this helps. c:
Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
so...
m = 0
b = -2
^^^Plug these numbers into formula
y = 0*x - 2
y = 0 - 2
y = -2
