Answer:
Step 2: He should have added 3 to, rather than subtracting 3 from, both sides.
Step-by-step explanation:
1. Combine like terms: 6b − 3 = −21
2. Subtraction property of equality: 6b = −24
Here he has to add 3 on both sides, to isolate the variable term.
Therefore, answer is Step2) He should have added 3 to, rather than subtracting 3 from, both sides.
Hope this will helpful.
Thank you.
Answer:
The first choice
Step-by-step explanation:
The selling Price is S(x) = 100x^3 + 6x^2 + 97x + 215
<u>The cost = C(x) = 88x - 215</u>
The Profit = S(x) - C(x) = 100x^3 + 6x^2 + 9x
The answer is The First Choice
The roots of a quadratic equation depends on the discriminant 
.
- If
, the quadratic equation has two real distinct roots, and it crosses the x-axis twice. - If
, the quadratic equation has one real root, and it touches the x-axis. - If
, the quadratic equation has two complex roots, and it neither crosses nor touches the x-axis.
---------------------
A quadratic equation has the following format:
It's roots are:
Thus
They are given by:
The discriminant is .
- If it is positive,
, and thus, the quadratic equation has two real distinct roots, and it crosses the x-axis twice.
- If it is zero,
, and thus, it has one real root, and touching the x-axis.
- If it is negative,
is a complex number, and thus, the roots will be complex and will not touch the x-axis.
