Answer:
<h2>x = 5 , x = -3</h2>
Step-by-step explanation:
x^2 - 2x = 15
x^2 - 2x - 15 = 15 - 15 (Subtract 15 from both sides.)
x^2 - 2x -15 = 0 (Simplify.)

<em>Set up & solve for a quadratic formula</em>
<h3><em>* I will solve for your first x</em></h3>
2 + root 64 / 2x 1 = 2 + root 64 / 2
root 64 = 8
= 2 + 8 / 2
= 10 / 2
= 5
<em>To solve for the second, follow the same pattern/formula for the first that I used to get 5.</em>
The given table is
c 1 2 3 4 5
f 6 6 7 8 8
c = the number of children
f = the fee per hour
The given information is
f = $6 when c = 2;
f = $7 when c = 3;
f = $8 when c = 4 or c = 5.
A graph of the data is shown below.
Notice that the fee for 1 child was not provided, but it was provided in the table.
Let us examine the given answers.
(a) The relationship is not linear between c and f.
TRUE
(b) The relationship is linear between c and f.
FALSE
(c) The relationship is not linear for and linear for f.
FALSE
(d) The relationship is linear for c but not f.
FALSE
Answer: The relationship is not linear between c and f.
8,350 lb.
1 ton = 2000 lbs, 2000 x 4 = 8000 + 350 lbs = 8,350 lbs
