Answer: <u> </u><u> </u><u>3</u><u> </u><u>+</u><u> </u><u>1</u><u>0</u><u>i</u><u> </u>

Step-by-step explanation:

= { \rm{(8 + 7i) - (5 - 3i)}} \\  \\  = { \rm{(8 - 5) + (7 + 3)i}} \\  \\ { =  \rm{3 + 10i}}

(8 + 7i) - (5 - 3i)

\longrightarrow \: (8 + 7i - 5 + 3i)

\longrightarrow \: (3 + 10i)

3+10i is the difference between the current of the two circuits

dimulka [17.4K]

Answer:

3.471 + 7.2516 x

Step-by-step explanation:

Given the data:

(1,3) (2,0) (5,-8) (9, -25) .

X:

1

2

5

9

Y:

3

0

-8

-25

The line of best fit for the data given can be obtained using an online regression calculator :

The equation of best fit for the data is thus;

Best fit equation; y = -3.471 + 7.2516x

Intercept = - 3.471 ;

Slope = 7.2516

Write the equation of line in slope-intercept form :Line parallel to the y-axis that passes through the point (77,88) PLZ HELP
sammy [17]

A line parallel to the y-axis that passes through (77,88) is x = 77.  There is no slope-intercept form of this equation if our coordinate system is based upon a horizontal x-axis and a vertical y-axis.

Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).
spin [16.1K]
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
