Answer:y=3/4x-2
(I’m an expert of this)
To simplify 9/56 is easy. You need to find a common factor. For this, the easiest method is to jot them down.
1,3,9
1,2,4,6,7,8,9,14,23,56
As you can see, 9 is the only large common factor. Do if you divide 9 by 9 you get 1 and 56 by 9 you get 6. The answer therefore would be 1/6.
Answer:
8. x=-5 and y=7
9. x=-2 and y=0
10. x=-6 and y=-10
11. x=8 and y=-4
12. x=9 and y=-9
13.x=4 and y=10
14. x=5 and y=-7

Answer:
linear. Each week adds another 10 dollars.
Step-by-step explanation:
Total = 340 + 10*w
w is the weekly amount
Suppose 5 weeks pass
Then the total amount in her bank account is
Total = 340 + 10*5
Total = 340 + 50
Total = 390
The equation is Linear.
Answer:
The correct choices are 2,3,5
Step-by-step explanation:
We can write an exponential decay function for this problem
y= ab^x
where a is the initial value
b is 1 - decay rate
x is the time
y= 70000 (1-.5) ^x where x is the number of 4 hour periods
y = 70000 (.5)^x
The half life is every 4 hours
24 hours is 24/4 = 6
y = 70000 (.5)^6
y = 1093.75 at 24 hours
