Re-write the quadratic function below in Standard Form y= -9(x+3)2+2
disa [49]

Answer:

18x+y=-52

Step-by-step explanation:

we all know and love(being 100% sarcastic here)the standard form  as

ax+by=c

y=-9(x+3)*2+2----This is weird and not so nice

so lets make it nice by distributing the 9::::

y=(-9x-27)2+2

and now the 2:

y=-18x-54+2

y=-18x-52

oops this is NOT in S.F we got to switch the -52 and y

52=-18x-y

-18 cant be neg. so we have to divide by -1 on both sides

-52=18x+y

18x+y=-52

HOPE THIS HELPS

Solve using elimination 6x-3y=12 and 4x-3y=24 <br> (6,16)<br> (-6,-16)<br> (6,-16)<br> (-6,16)
GrogVix [38]

-1(4x-3y=24)

6x-3y=12

-4x+3y=-24

2x=-12

x=-6

6(-6)-3y=12

-36-3y=12

-3y=48

What is the parent equation for exponential growth and decay?
Archy [21]

Answer:

A = P x r^t

Step-by-step explanation:

A = Amount (e.g. number of organisms in population after certain period of time)

P = Principal/ Initial Value (e.g. the starting population)

r = rate as a decimal (e.g. if a population increases over certain period of time by 20%, r would equal 1.2)

t = time in whichever units you need.

Example of problem using formula:

A population of 2000 decreases by 20% every year, find the population size after 5 years.

A = ?

P = 2000

r = 0.8

t = 5

A = Pxr^t

A = 2000 x 0.8^5

A = 655.36

Hope this helped!
