Answer:

m = ---

Step-by-step explanation:

The formula is y2-y1

---------

x2-x1

(x1,y1) (x2,y2)

(3,-5) (-9,-6)

You get the 2 Y's and subtract them

Do the same with the X's

Y's above , X's below

(y2- y1)

⬇

-6-(-5) -1 1

--------- = ---- = ---- = m

-9-(3) -12 12

⬆

(×2- x1)

This equation is backwards, thats why it was harder to understand. (-9,-6) is farther left and below point (3,-5), making it the REAL first point in the equation.

If Ray is 10yrs old,then

(X+6)/2 = 10,

x+6 = 20

x = 14

Is -2t^2+3t+4 in standard form

Paul [167]

Answer:

$-2t^2+3t+4$ or $-2t^2+3t^1+4t^0$

Step-by-step explanation:

The equation is already written in standard form.

You write the largest exponents to the left and the smallest to the right.

Your expression: $-2t^2+3t+4$ can also be expressed as this below:

$-2t^2+3t^1+4t^0$

t to the first power means mutiplying by t

t to the 0 power mean mutiplying by 1 or basically you get the same result

If t was 2...

$3t= 3(2)=6\\3t^1=3(2)^1=3(2)=6$

Same result:

$4=4\\4t^0=4(2)^0=4(1)=4\\$
