You can immediately see that the vertex is located at (-3,-2) and that the y-intercept is 7 or very close to 7.

The general equation for a parabola with vertex at (h,k) is

y-k = (x-h)^2, and from that and the given info, we get:

y-(-2) = (x-(-3))^2, or y+2 = (x+3)^2, or y = (x+3)^2 - 2.

Enter the correct answer in the box. What is this expression in simplified form? <br> 3\sqrt{88}

Ugo [173]

Answer: $12\sqrt{5}$

Step-by-step explanation:

$3\sqrt{88}$

88 can be rewritten as 8 x 10 and 8 can be rewritten as $2^2*2$ making a 2 come out of the root.

$3\sqrt{2^2*2*10}\\ 3*2\sqrt{2*10}\\6\sqrt{2*10}$

10 can be rewritten as 2 x 5.

$6\sqrt{2*2*5}$

2*2 can also be rewritten as $2^2$ making a 2 come out of the root.

$6\sqrt{2^2*5}\\ 6*2\sqrt{5}\\ 12\sqrt{5}$

We can't keep simplifying the root.

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.

$250 = 15x+ 100$
