a) (-5,0)
c)x=-5
2. image attached
a) when finding the zeros or roots of the quadratic
3. the discriminant of a polynomial is a quantity that depends on the coefficients and determines various properties of the roots.
a) b^2-4ac
Answer:
Step-by-step explanation:
Note: y = 10 when x = 5 is already given, must be find x for y = 5.
<u>y = k/x is the formula, using the given values finding the constant:</u>
<u>So for y=5 we have:</u>
Answer:
C.
Step-by-step explanation:
We use the Quadractic Formula: 
*Excuse the bad ± (plus or minus) sign. It wouldn't let me put it in the equation maker
<em>a</em> = 1
<em>b</em> = -5
<em>c</em> = 7
Step 1: Plug in our variables

Step 2: Solve


√-3 is equal to √-1 times √3, and √-1 is equal to imaginary i
Thus, we have:
(5 ± i√3)/2 or (5 + i√3)/2 and (5 - i√3)/2
Answer:
y=16
Step-by-step explanation:
4x+3y=24,
3y=24-4x
3y= 24 - 4*(-6)
3y= 24 + 24
3y= 48
3y/3 = 48/ 3
y= 16
