16x16 is the correct Answer
Answer:y intercept is -2
Step-by-step explanation:
Because the equation line formula
Y=mx+b
Where m is slope and b is y- intercept
Therefore
Y=-4x-2
Your b is the -2
Answer:
52.5
Step-by-step explanation:
=24.5/7
=3.5
Then
3.5*15
=52.5 ans#
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.
