Answer:
Step-by-step explanation:
The discriminant comes from the quadratic formula. We use the discriminant to determine, before factoring, what types of solutions we can expect when we do factor. In the quadratic formula, the discriminant is under a square root sign. If the number under a square root sign is negative (meaning the discriminant is negative), we will not have real number solutions because you can't have a negative number under a square root. So a is your choice.
Answer:
(2a, 0)
Step-by-step explanation:
the distance from (a,0) and z from the origin and to each other is both 3. It’s in the middle of two points, there’s an equal distance between w to y and y to z. I hope that makes sense, so, to get the x coordinate multiply a by 2.
7/8=14/16=21/24 etc.
Hope this helps! :)
<h3>The system of equations has infinitely many solutions</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
y = x + 2 ------ eqn 1
-3x + 3y = 6 -------- eqn 2
Solve the system of equations by substitution method
Substitute eqn 1 in eqn 2
-3x + 3(x + 2) = 6
-3x + 3x + 6 = 6
-3x + 3x = 6 - 6
0 = 0
If we end up with the same term on both sides of the equal sign, then we have infinite solutions
Thus the system of equations has infinitely many solutions
