What is the axis of symmetry of the function f(x)= -(x+9)(x-21)
Vinil7 [7]

Answer:

The axis of symmetry is x = 6

Step-by-step explanation:

To find this, first find the two x-intercept values and then take the average. This will always be the line of symmetry.

x + 9 = 0

x = -9

x - 21 = 0

x = 21

Now take the average of these two numbers.

(-9 + 21)/2

12/2

You open a bank account with $100 and deposit 15 every week. Create an equation to model the total amount of money,y, in dollars
Charra [1.4K]

Answer:

Y = 15x+ 100

x = 10 months

Step-by-step explanation:

Given:

Initial deposit = $100

Weakly deposit = $15

Solution:

We need to create an equation where total amount is y is equal to initial deposit plus multiplication of weakly deposit and month x, so the equation is written as.

Y = 15x+ 100 ---------(1)

Where:

Y = Total amount

x = Number of months.

Second thing we need to find the month for y = $250

Now, we substitute y = 250 in equation 1.

250 = 15x+ 100

15x=250-100

15x =150

x=\frac{150}{15}

x = 10 months

Therefore, we need to required 10 months for $250.
