Answer:
The ends of the field are at the zeros (x-intercept) of the function.
0 = -0.000234(x - 80)2 + 1.5 subtract 1.5 from both sides
-1.5 = -0.000234(x - 80)2 divide both sides by right coefficient
6410.25641 = (x - 80)2 take square root of both sides
80.064 = x - 80 add 8-0 to both sides
160.064 = x
The field is 160.064 feet wide.
The maximum is at the vertex, y = 1.5 feet

<em>To find the zero,</em>
<em>x</em> + 1 - 4 = 0
<em>x</em> = 4 - 1
<em>x</em> = 3
3 is the <u>root</u> of <em>(x + 1) - 4</em>.
Answer:
x = -72
Step-by-step explanation:
...................
19/42=9 The input is a contradiction it has no solutions.
Answer:
x ≥ 12
Step-by-step explanation:
Step 1: subtract 2 from both sides
Now you have; -3/4 x ≤ -9
Step 2: divide both sides by -3/4
Now you have x ≥ 12
(when dividing an inequality by a negative you have to flip the sign)
Therefore the answer is x ≥ 12
