Problem as entered: <span><span>15 - 19</span><span>1010</span></span>
<span><span>In 15, multiply the whole number, '1', by the denominator of the fraction, '10' to get '10'. This shows that the whole number represents
10.</span><span>1010</span></span>
To find the numerator when this mixed number is shown as an improper fraction, use addition.
<span><span>10 + 5 = 15</span><span>101010</span></span>
<span><span>In 19, multiply the whole number, '1', by the denominator of the fraction, '10' to get '10'. This shows that the whole number represents
10.</span><span>1010</span></span>
To find the numerator when this mixed number is shown as an improper fraction, use addition.
<span><span>10 + 9 = 19</span><span>101010</span></span>
The addition is now simpler because the whole numbers have been eliminated, leaving only two fractions.
<span><span>15 - 19</span><span>1010</span></span>
Subtract the numerators.

The graph of a quadratic function has roots at -3 and -7 and a vertex at (-5, 4). What is the equation of the function in vertex
melomori [17]

Answer:

y = -(x + 5)² + 4

Step-by-step explanation:

The roots are -3 and -7, so:

y = a (x + 3) (x + 7)

Distribute and complete the square:

y = a (x² + 10x + 21)

y = a (x² + 10x + 25 − 4)

y = a (x² + 10x + 25) − 4a

y = a (x + 5)² − 4a

The vertex is (-5, 4), so a = -1.

y = -(x + 5)² + 4
