Answer:
x = -5
Step-by-step explanation:
the first step is calculate the sum.
-9x - 31 = 14
Then move the constant to the right side and change the sign.
-9x = 14 + 31
Then add the numbers
-9x = 45
Then divide both sides of the equation by -9
x = -5
So this problem
can be solve using the formula:
F = P(1+i)^t
Where F is the
balance account after t years
P is money
deposited
i is the
fraction interest rate
F = 3500 (1+0.35)^t
<span>F = 3500 (1.35)^t
is the function equation represents the balance of the account after t years</span>
divide total ounces by the amount each cup can hold
678 / 8 = 84.75
so they can fill 84 cups
You determine whether the parabola opens upward, with a positive x^2. It opens downward with a negative x^2.
f(x) is a maximum
g(x) is a minimum
