Answer:

see attached

Step-by-step explanation:

The transformations are ...

(x, y) ⇒ (-y, x) . . . . 90° rotation

(x, y) ⇒ (-x, -y) . . . . 180° rotation

(x, y) ⇒ (y, -x) . . . . 270° rotation

Each successive rotation is a 90° rotation from the previous one. This makes writing the formulas in a spreadsheet really easy. The attached shows the transformed coordinates.

How to find Slope on a graph?

UNO [17]

Answer:

there are several ways to write, and find slope...see explanation

Step-by-step explanation:

Way 1: slope Intercept- y=mx+b

step 1: find where the line crosses the Y axis(the one running up and down...thats is your "b" so if the line crosses at -2...it would be this: y=mx-2

Step 2:from the point where the line crosses the Y axis, count how many up/down and Left/right to the next point..so if you go up 2 right 1, it would look like this y=2x-2

Up=positive

down=negative

left=negative

right=positive

Suppose you invest $950 at an annual interest rate of 6.5% compounded continuously. How much will you have in the account after

UNO [17]

Present value, P = 950
interest rate, i = 6.5% continuous
Number of periods, n = 10 years

Future value
$F=Pe^{it}$
$=950e^{.065*10}$
$=1819.76$ to the nearest cent

Solve for X<br> (10x - 1)=(14x - 37)

stich3 [128]

(make them equal to each other)

10x-1 = 14x-37

(combine like terms)

-4x = -36

(divide by -4)

x=9

Midpoints of segment with endpoints. (-4,2) and (2,4)

sashaice [31]

Well! See ,If the endpoints are (x1,y1) & (x2,y2) then mid-point is given by (x1+x2)/2,

(y1+y2)/2

Here in this question endpoints given for the line segment are (-4,2) , (2,4) so we have to find mid-point for x and y co-ordinates by applying above rule.

So, the mid-point we get is (-4+2)/2 , (2+4)/2.

i.e. (-1,3) which lies in 2nd Co-ordinate!

Hope it helps!!
