Write quadratic function with zeros 3,6
kaheart [24]

Answer:

y=x^2-9x+18

Step-by-step explanation:

If x1=3 and x2=6, then the equation for the zeroes would be (x-3)(x-6)=0, which can then be expanded to x^2-9x+18=0, making the function y=x^2-9x+18

a $7,000 principal is invested in two accounts, one earning 3% interest and another earning 7% interest. if the total interest f
Ksju [112]

Let the investment in first account be x and this account is earning 3% interest

So Interest on this account is 3% of x = 0.03x

So the investment in second account would be (7000-x) and this account is earning 7% interest

So the interest on this account is 7% of (7000-x) = 0.07*(7000-x)

Given that total interest for the year is $262

So we have

0.03x + 0.07(7000-x) = 262

0.03x - 0.07x + 0.07*7000 = 262

-0,04x + 490 = 262

-0.04x = 262-490

-0.04x = - 228

0.04x = 228x

x = 228/0.04

x = 5700

Therefore Investment in one account s 5700 and the investment in other account is 7000-5700 = 1300

Click to see equation, show work pls!

Answer:

x = 6, 9

Step 1:

To solve this equation, we need to subtract 3 from both sides like this:

3\sqrt{x-5} +3(-3)=x(-3)\\3\sqrt{x-5} =x-3

Step 2:

We square both sides (multiply using FOIL) to get rid of the radical.

(3\sqrt{x-5} )^2 = (x-3)^2\\(3\sqrt{x-5} )^2: 9x-45\\ (x-3)^2: x^2+6x+9\\\\9x-45=x^2-6x+9

If you did not understand how these were done, here is an example:

(x + 1)(x + 2)

First terms: x * x = <u><em>x^2</em></u>

Outer terms: x * 2 = 2x

Inner terms: 1 * x = x

2x - x = <u><em>x</em></u>

Last terms: 1 * 2 =<em> </em><u><em>2</em></u>

x^2 + x + 2

Step 3:

Solve for x:

9x - 45 = x^2 - 6x + 9

x^2 - 6x + 9 (+45) = 9x - 45 (+45)

x^2 - 6x + 54 (-9x) = 9x (-9x)

x^2 - 15x + 54 = 0

Factor:

(x^2 - 6x) + (- 9x + 54)

x(x - 6)        - 9(x - 6)

Factor out (x - 6):

(x - 6)(x - 9) = 0

x - 6 = 0; 6 - 6 = 0

x - 9 = 0; 9 - 9 = 0

Our anwer: x = 6, 9
