Sounds like "exponential decay" is the answer your teacher is looking for
Expressions of the form y = a*b^x are considered decay equations or exponential decay equations if 0 < b < 1. So b can be between 0 and 1, but not equal to either endpoint.
Example: y = 3*0.5^x means we start off with 3 as the initial value, and then cut it in half repeatedly as x increases by 1 (eg: x = 0, x = 1, etc). This graph goes downhill as you read it from left to right.
Answer:
Hey!
Your answer is Y= -2x + 9!!
Step-by-step explanation:
hope this helps!!
- The distance travelled by both Evelyn and Ricky is 45 miles
If Speed = dist/time, then;
<u>dist = speed * time</u>
<u />
We also know that both of them travel the same distance, so we equate the distance travelled to each other
36 * x+45 = 72 * x
36x + 1620 = 72x
72x - 36x = 1620
36x = 1620
x = 1620/36
<u>x = 45 miles</u>

Answer:
3(2x+4)+2(x-2)
6x+12+2x-4
6x+2x+12-4
8x+8
I am from grade 9 from which grade are you
$250 = $75 + ?
45 × 3 = 135
135 + 75 = 210
210 + 45 = 255
? = 180
$75 + ( 45 × 4 ) = 255
so she could save up 4 weeks worth of money plus the other 75 with an extra $5 to spend or save for something
