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>
Hey there!
Given rule is 2x-8
Given x = 8
On substituting ,
=> 2(8)-8
=> 16-8
=> 8
8 is the answer mate!

Answer:
y=250x-4
Step-by-step explanation:
If y represents the amount of money made in a week, y=250.
If x represents the amount of cakes that are made, x=?
You make $250(y) a week, you then spend $4(x) per cake, this would make the equation:
y=250x-4
Answer: 14.7338936% decrease

cross-multiply
85.2661064 = x
100 - 85.2661064 = 14.7338936
Check: 0.852661064 * 5355 = 4566
If permitted, you may round for a simpler (yet less precise and exact) answer. For instance, rounding to the hundredths would make it ~14.73%.
