1 answer:
Alina [70]3 years ago

Answer:

y = x² + 6x + 8

Step-by-step explanation:

The zeros ( x- intercepts ) of the graph are x = - 4 and x = - 2, thus

the factors are (x + 4) and (x + 2) and the function is the product of the factors.

y = a(x + 4)(x + 2) ← a is a multiplier

To find a substitute (0, 8 ) the y- intercept into the equation

8 = a(0 + 4)(0 + 2) = a(4)(2) = 8a ( divide both sides by 8 )

a = 1, thus

y = (x + 4)(x + 2) ← expand using FOIL

  = x² + 6x + 8

astra-53 [7]

Answer:

When Aria sold her house after eleven years it worth was <u>$95,300</u>.

Step-by-step explanation:

Given:

Aria paid $75,000 for her house. Its property value increased by 2.2% per year.

Now, to find the worth of Aria house when sold after eleven years.

Let the amount of house after eleven years be x.

Amount Aria paid for her house (A) = $75,000.

Rate of property increased per year (r) = 2.2%.

Time (t) = 11 years.

Now, to get the amount of house after eleven years we put formula:

x=A\times (1+\frac{r}{100})^{11}

x=75000\times (1+\frac{2.2}{100})^{11}

x=75000\times (1+0.022)^{11}

x=75000\times (1.022)^{11}

x=75000\times 1.2704

x=95280.

<em>The amount of house after eleven years to the nearest hundred dollars is $95,300.</em>

Therefore, when Aria sold her house after eleven years it worth was $95,300.
