Solve system by elimination -9x - y =-19 <br> 5x + y = 15

vredina [299]

Answer:

(1, 10 )

Step-by-step explanation:

Given the 2 equations

- 9x - y = - 19 → (1)

5x + y = 15 → (2)

Adding the 2 equations term by term will eliminate the y- term

- 4x + 0 = - 4

- 4x = - 4 ( divide both sides by - 4 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

5(1) + y = 15

5 + y = 15 ( subtract 5 from both sides )

y = 10

solution is (1, 10 )

State the value of the discriminant for the equation,<br> 3x^2 + 7x + 3 = 0

Irina-Kira [14]

Answer: 13

Step-by-step explanation:

If you remember the quadratic equation formula;

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

You can easily extract what is under the root to find the discriminant.

$b^2-4ac=?\\$

a = 3

b = 7

c = 3

$(7)^2-4(3)(3)\\49-36=13$
