Well..
means "subtract 9 from 
".
If is 15, then it means "subtract 9 from 15". That's all you need to do.
Answer:
If one of the data points has the form \displaystyle \left(0,a\right)(0,a), then a is the initial value. Using a, substitute the second point into the equation \displaystyle f\left(x\right)=a{\left(b\right)}^{x}f(x)=a(b)
x
, and solve for b.
If neither of the data points have the form \displaystyle \left(0,a\right)(0,a), substitute both points into two equations with the form \displaystyle f\left(x\right)=a{\left(b\right)}^{x}f(x)=a(b)
x
. Solve the resulting system of two equations in two unknowns to find a and b.
Using the a and b found in the steps above, write the exponential function in the form \displaystyle f\left(x\right)=a{\left(b\right)}^{x}f(x)=a(b)
x
.
Step-by-step explanation:
5x + 2y - 2x + 8 = (5x - 2x) + 2y + 8 = 3x + 2y + 8
Hey there!
Andrea makes 20% more than Cassidy.
Work:
10 x 0.20 = 2
10 - 2 = 8
So that proves it is 20%.
Hope this helps!
Answer:
15% probability that 7 adults selected at random from the town all have health insurance.
Step-by-step explanation:
(sample/population)^number of times selected
(76/100)^7 = (0.76)^7 = 0.15 = 15%
