Answer:

(- 4, - 5 )

Step-by-step explanation:

Given the 2 equations

2x - y = - 3 → (1)

3x + 4y = - 32 → (2)

Multiplying (1) by 4 and adding to (2) will eliminate the term in y

8x - 4y = - 12 → (3)

Add (2) and (3) term by term to eliminate y

11x = - 44 ( divide both sides by 11 )

x = - 4

Substitute x = - 4 into either of the 2 equations for corresponding value of y

Substituting in (2) gives

3(- 4) + 4y = - 32

- 12 + 4y = - 32 ( add 12 to both sides )

4y = - 20 ( divide both sides by 4 )

y = - 5

Solution is (- 4, - 5 )

Solve using the quadratic formula x2 - 6x - 40=0 Question options: x = 10 or x = -4 x = 4 or x = -10 x = -7 or x = 7 x = -4 - √7
Crazy boy [7]

Answer:

x=-10 or x=4

Step-by-step explanation:

ax^2+bx+c=0

x^2-6x-40=0

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

x=\frac{-6\pm\sqrt{6^2-4(1)(-40)}}{2(1)}

x=\frac{-6\pm\sqrt{36+160}}{2}

x=\frac{-6\pm\sqrt{196}}{2}

x=\frac{-6\pm14}{2}

x=-3\pm7

x=-10 or x=4
