Equation: y =4 x
when x =1 , y = 3,
when x = 2, y =6, From the table, we see that y = 3x
when x =3 , y = 9
Which representation has the greatest slope?
O The table has the greatest slope. NO
O Their slopes cannot be determined. NO
O The table and equation have the same slope. NO
O The equation has the greatest slope. YES
Hey there!
2x + 7 = 27
2x = 20
x = 10
3x + 1 = 28
3x = 27
x = 9
The values for both of these equations are 9 and 10; therefore, the answers are not equivalent.
I hope this helps!

Answer:
there are two complex roots
Step-by-step explanation:
Recall that for a quadratic equation
y = ax² + bx + c
the solution given by the quadratic formula is
x = ( -b ± √discriminant) / 2a
if the discriminant is negative, the radical term will become √ (negative number), which we know gives complex solutions. Hence we can eliminate real roots as possible answers.
Also notice that the "±" sign in the quadratic formula means that you will get 2 possible solutions:
x = ( -b + √discriminant) / 2a
or
x = ( -b - √discriminant) / 2a
Hence we know we will get 2 solutions.
Combining our findings, we can conclude that if the discriminant is negative, we will get 2 complex roots.
