Answer:
3-i
Step-by-step explanation:
1-5i + 2 +4i
We add the real parts
1+2 =3
We add the imaginary parts
-5i + 4i = -1i
The complex number is
3-i
Answer:
C
Step-by-step explanation:
the line seems to either separate or have multiple y places for 1 x place, making it not continuous at x=0 where this happens
Answer:
6
9
6.48
Step-by-step explanation:
this is the easiest way to solve for percentage:
Where all the percents (except 100) would go in part
and the whole number would go in whole
Then multiply 24 × 25 ÷ 100 = 6
Multiply 60 by 25 then divided by 100 = 9
Then for the last one 9 is what percent of 72
all we have to do is multiply 9 and then convert 72 into a decimal (0.72)
Then 9 × 0.72 = 6.48
So, both equations are essentially linear equations.
Linear equations are written in the format
y = mx+b, where
m represents the
slope/slope intercept and
b represents the
y-intercept.
---------------------------------------------------------------------------------------------------------------
Part Athe slope and y-intercept
y = mx +b
m - the slope; b- y-intercept
therefore;
y = 6x - 4
m = 6; b = -4y = 5x - 3
m = 5; b = -3The coordinates of the point where the lines are crossed are the solution to the system of linear equations.
How to graph the lines:
y = 6x - 4
y-intercept (0; -4)
for x = 1 ⇒ y = 6 · 1 - 4 = 6 - 4 = 2 ⇒ (1; 2)
y = 5x - 3
y-intercept (0; -3)
for x=1 ⇒ y = 5 · 1 - 3 = 5 - 3 = 2 ⇒ (1; 2)
***look at the img for graph reference***Part B:
x = 1; y = 2
<span>Circumference of a circle = 2 π r
(where r is the radius)
Area of a circle = π r^2
(where r is the radius)
you have to find the radius
C = 2π unit
r = 1 unit
Area = π square units
