Answer:
Real part = -5
Step-by-step explanation:
The real part of a complex number of the form a+bi, is that which doesn't have the "i" (imaginary unit) factor. therefore the real part is "a"
In this case (-5+3i) the real part is -5.
Answer: The price after the mark up is $151.20
Step-by-step explanation:
8/100 x 140 = $ 11.20
140 + 11.20 = $ 151.20
I hope this helps in any way :)
Answer:
Step-by-step explanation:
5.7 + 2(w+1) = 2w + 9
5.7 + 2w + 2 = 2w + 9
7.7 = 9, which is impossible, so there is no solution.
:::::
-8(4+9r) = 7(-2-11r)
-32-72r = -14-77r
5r = 18
r = 3.6
Assuming M is midpoint of RS
the midpoint formula is
x term of the midpoint is average of the x value of the 2 points
y term of the midpoint is average of the y value of the 2 points
if R is (x,y)
S is (6,1)
x value of midpoint is 4
x value of S is 6
x value os R is x
so
average of x and 6 is 4,
(x+6)/2=4,
x+6=8,
x=2
y value of midoint is 2
y value of S is 1
y value of R is y
average of 1 and y is 2
(y+1)/2=2
y+1=4
y=3
the midpoint is (2,3)
Answer:
s = 10w
Step-by-step explanation:
First we need to find the slope
Since the point goes through (0,0), the slope is y/x
Using the point (1,10)
10/1 = 10
The equation is
y = mx+b
The slope is m and the y intercept is b
The slope is 10 and the b intercept is 0
y = 10x
Changing to the variables on the graph
s = 10w
