Total age
<span>6 * 27 </span>
<span>162 </span>
<span>Subtotal age of first 4 </span>
<span>4 * 23 </span>
<span>92 </span>
<span>Subtotal of last 3 </span>
<span>3 * 34 </span>
<span>102 </span>
<span>In the total of the first 4 and last 3 </span>
<span>the 4th person has been counted twice. </span>
<span>This second time must be subtracted. </span>
<span>Therefor </span>
<span>92 + 102 - x = 162 </span>
<span>194 - x = 162 </span>
<span>Subtract 194 from both sides </span>
<span>-x = -32 </span>
<span>Multiply both sides by -1 </span>
<span>x = 32

(y - 5)/3 = 1
y - 5 = 3 x 1 = 3
y = 3 + 5 = 8
6x + 29 = 5
6x = 5 - 29 = -24
x = -24/6 = -4
Answer:
-5 and 3
Step-by-step explanation:
The roots of a quadratic function are also called the x intercepts.
The x intercepts are found by looking where where the quadratic equation crosses the x, or horizontal axis.
In this case, the quadratic equation crosses the x axis at (-5,0) and (3,0).
Therefore, our roots are -5 and 3
