Answer:

y = -2*0.5ˣ

Step-by-step explanation:

general formula for exponential function: y = abˣ

for point (0 , -2):    -2 = a*b⁰ = a * 1 = a

a = -2

for point (-1 , -4):   -4 = (-2) * b⁻¹       b⁻¹ = (-4) / (-2) = 2    

b = 1/2

exponential function:     y = -2*0.5ˣ

I have 18 ones 15 hundreds 15 tens 8thousands what number am I
tankabanditka [31]
8 thousands is equal to 8000.
15 hundreds is equal to 1500.
15 tens is equal to 150.
18 ones is equal to 18.

So just add them up.
8000 + 1500 = 9500.
9500 + 150 = 9650.
9650 + 18 = 9668.

The number is 9668

PLEASE HELP W/ THIS ASAP!!
Leni [432]

Answer:

- 1.375

Step-by-step explanation:

Each dot is worth -1/8 of a unit when moving left.

So the coordinates of the dark dot are - 1 and - 3/8

or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
