The zeros of the function are also called the roots. Thus, this problem is basically locating the root of the given equation.

To locate the roots, we equate the equation f(x) to 0.

We then dissect each term to identify a, b, and c in the quadratic equation formula:

x = (- b +- √(b²-4ac))/2a

a = 2
b = 8
c = -3

x1 = 0.3452
x2 = -4.345

A box contains 12 1/2 square feet of tiles and costs $40.21 what is the approximate price per square foot
frutty [35]
40.21/12.5
We would do this because the problem asks for unit rate
And and we need to find out the cost for one square foot
40.21/12.5 = 3.2168
We need to round this ANSWER and round it or else it will be incorrect
The answer would round to 3.22
Therefore, the answer is $3.22 per square foot

Y is such that 4y _ 7&lt;= 3y and 3y &lt;= 5y +8. What range of values of y satisfies both inequalities
fgiga [73]

Answer:

<h3>-4≤y≤7</h3>

Step-by-step explanation:

Given the inequality expressions

4y - 7 ≤ 3y and 3y≤5y+8

For 4y - 7 ≤ 3y

Collect like terms

4y - 3y ≤ 7

y ≤ 7

For  3y≤5y+8

Collect like terms

3y - 5y ≤ 8

-2y ≤ 8

y ≥ 8/-2

y ≥ -4

Combining both solutions

-4≤y≤7

<em>Hence the range of values of y that satisfies both inequalities is -4≤y≤7</em>
