Step-by-step explanation:
Let's pretend our point is actually a complex number. That would make the point -2–3i. Why would we do this? Well, rotation of complex numbers is simply a matter of multiplication, in this case by 1∠−90° , or -i.
So to start, you shift the point of rotation to 0+0i, rotate it by multiplying, then shift it back to the axis of rotation.
z=−i[(−2−x0)+(−3−y0)i]+(x0+iy0)
=−3−y0+x0+(2+x0+y0)i
x=Rz
y=Iz
Thus the new point is at (−3+x0−y0,2+x0+y0)
hence (-3,2)
Select the correct answer.
If a line crosses the yaxis at (0, 1) and has a slope of 4/5', what is the equation of the line?
O A 4y-5x= 5
OB. y - 4x = 5
OC. 5y + 4x = 5
OD. 5y - 4x = 5
Answer:
Your correct answer should be D.

Answer:
The answer would be 32
Step-by-step explanation:
equation would be: 6+2(12+1)
which then turns into 6+24+2
which equals 32
Answer:
32
Step-by-step explanation:
Since a = 3, b = 4, and c = -1
The Equation is:
= 2 × (3) + 2 × [(3) × (4) - (-1)]
= 6 + 2 × [12 - (-1)]
= 6 + 2 × (12 + 1)
= 6 + 2 × 13
= 6 + 26
= 32

HELP!!!
Jacob and Paul are playing a game of cards. After the first round, Jacob said that Paul's score would be twice his own score if he earned 7 more points.
Paul responded to Jacob by telling him his score was only 6 points higher then Jacobs.
PART A. write a system of equations to represent each of the boys statements. Be sure to specify what your variables represent.
PART B. If they both are correct. How many points did each if the boys score??
MY LAST POST GOT REMOVED PLS HELP I NEED THIS DONE TODAY!!
Interpreting the situation, we have that:
a) The system of equations is:
[tex]y = 2x - 7[/tex]
[tex]y = 6 + x[/tex]
b) Solving the above system, it is found that Jacob scored 13 and Paul scored 19.
Item a:
In our system, we have that:
Jacob's score is of x.Paul's score is of y.Jacob said that Paul's score would be twice his own score if he earned 7 more points, which means that:
[tex]y + 7 = 2x[/tex]
[tex]y = 2x - 7[/tex]
Paul responded to Jacob by telling him his score was only 6 points higher then Jacob's, which means that:
[tex]y = 6 + x[/tex]
Item b:
Equaling both equations:
[tex]2x - 7 = 6 + x[/tex]
[tex]x = 13[/tex]
[tex]y = 6 + x = 6 + 13 = 19[/tex]
Jacob scored 13 and Paul scored 19.

h(-3) means that we put the argument (-3) into the formula of the function everywhere where there is x.
h(x) = -3x - 10
so,
h(-3) = -3×-3 - 10 = 9 - 10 = -1
Answer:
-1
Step-by-step explanation:
h(x) = -3x - 10
h(-3) means to replace the x in the problem with the value of -3 and
solve.
h(-3) = -3(-3) - 10
h(-3) = 9 - 10
h(3) = -1
A rocket needs to reach a speed of 28,300 km/hr in order to get into orbit around Earth. How fast is this in miles per second.
Answer:
Step-by-step explanation:
1 km = 0. 621371 miles
28,300 km = 28,300* 0. 621371 miles = 17,584.7993 miles
1 hour = 60 *60 seconds = 3,600 seconds
speed of 28,300 km/hr =
17,584.7993 miles / 3,600 seconds ≈ 4.88 miles / second

Answer:
63gm
Step-by-step explanation:
7 gold : 4 silver
It gives you 36 silver.
to get from 4 silver to 36 silver you multiply by 9.
you multiply the gold by the same amount 9.
7*9= 63
you can see that for every 7 gold pieces there is 4 silver pieces. they keep piling up the pieces until there's 36 silver pieces. now they wanna know how much gold there is.
