You flip the signs when you are dividing by a negative value.
-2x+3>15
-2x>15-3
-2x>12
x<12/-2
x<-6
Now to test this
Try putting x in the original equation when it is -5.
-2(-5)+3>15
10+3>15
13>15
This is false because our answer says x is less than -6.
Now any value less than -6 will work so let's go with -7.
-2(-7)+3>15
14+3>15
17>15
This result is True.
Hope this helps out!
Answer:
a. This data best fits an exponential model.
b. The regression equation would be: y = 8385(1.12)^x
c. The y-intercept would be the starting value of the account.
d. Yes, the correlation coefficient is 0.9983.
e. If you input 6 into the equation, you will get a value of $16,550.
Step-by-step explanation:
I hope this helps, and I would appreciate the brainiest asap.
Multiply everything by 2 then combine like terms
