ANSWER:

<u>On solving equation by quadratic formula method, we get</u>

D = b² – 4ac

  • (–5)² – 4 × 1 × 3
  • 25 – 12
  • 13

D > 0, so it has real roots.

Now, x = – b ± √D/2a

  • – 5 ± √13/2

So, <u>Correct choice</u> - [A] & [C].

Answer:

solving equation by quadratic formula method, we get:

D = b² - 4ac

=(-5)² - 4 × 1 × 3

=25-12=13

D> 0,

so it has real roots.

x=- b ± √D/2a

- 5 ± √13/2

Correct choice [A] and [C].

Which is the approximate solution to the system y = 0.5x + 3.5 and y = −A system of equations. y equals 0.5 x plus 3.5. y equals
Elena L [17]

Answer:

The approximate solution of the system of equations is the point (-2.7,2.1)

Step-by-step explanation:

we have

y=0.5x+3.5 -----> equation A

y=-\frac{2}{3}x+\frac{1}{3} -----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (-2.714,2.143)

see the attached figure

therefore

The approximate solution of the system of equations is the point (-2.7,2.1)
