The required zero places of the given equation  y= x² + 5x + 6 is x = -2 and x = -3.

Given that,
An equation   y= x² + 5x + 6,
To determine the Zeros of the equation given above.

<h3>What is the equation?</h3>

The equation is the relationship between variables and is represented as y =ax + b is an example of a polynomial equation.

Here, given equation is, y= x² + 5x + 6
Now, let y = 0
x² + 5x + 6 = 0
x² + 2x + 3x + 6 = 0
x(x + 2) + 3 (x + 2) = 0
(x + 2) * (x + 3) = 0
x + 2 = 0    ;   x + 3 = 0
x = -2  and x = -3

Thus, the required zero places of the given equation  y= x² + 5x + 6 is x = -2 and x = -3.

How many ounces of a 15% alcohol solution must be mixed with 8 ounces of a 20% alcohol solution to make a 17% alcohol solution?
Tasya [4]

Step-by-step explanation:

x = ounces of 20% solution

15% = 0.15

20% = 0.2

17% = 0.17

x × 0.15 + 8×0.2 = (8 + x)×0.17

x×0.15 + 8×0.2 = 8×0.17 + x×0.17

8×0.2 = 8×0.17 + x×0.02

8×0.03 = x×0.02

x = 8×0.03/0.02 = 12 ounces

we need to mix the 8 ounces of 20% with 12 ounces of 15% to get 17% alcohol (8 + 12 = 20 ounces of it).

Sarah works as a waiter. She earns $80 each weekend plus 15% in tips. This weekend, Sarah earned $252.50 in all. What is the dol
amm1812

Answer:

The dollar amount of the meals Sarah served was $1150.

Step-by-step explanation:

Set up an equation expressing Sarah's total earnings:

(total earned) = (base wage) + 0.15 * (price of meals served)

Now the same using what we know:

$252.50 = $80 + 0.15 * x

where x is unknown and can be solved for:

x = (252.50 - 80) / 0.15 = $1150

The dollar amount of the meals Sarah served was $1150.
