7 0

it's the 4th one

Step-by-step explanation:

2x^2 - 8x + 16 = 9 + 16

2x^2 - 8x + 16 - 16 - 9 = 0

2x^2 - 8x - 9 = 0

so the answer is the fourth one

Solve 5x-y=5 and 2y-x^2=11 without using trial improvement
iren2701 [21]

Answer:

x = 7, y = 30  and  x = 3, y = 10

Step-by-step explanation:

5x - y = 5, then y = 5x - 5

2y - x^2 = 11

2(5x - 5) - x^2 = 11

10x - 10 - x^2 = 11

-x^2 + 10x -10 = 11

-x^2 + 10x -21 = 0

x^2 - 10x + 21 = 0

(x - 7)(x - 3) = 0

x = 7, y = 30

x = 3, y = 10

Complete the equation so that it has solutions of –5 and 7. x2 x = 0
Pavlova-9 [17]

The equation it has solutions of –5 and 7  is x^2-2x-37=0

We have equation

solutions of equation are –5 and 7.

We have to find complete the equation.

We have given that solutions of the equation are -5, 7.

The standard form of a quadratic equation.

<h3>What is the factor of the quadratic equation?</h3>

(x -\alpha) (x- \beta)

Where we have

p = -(\alpha+\beta)  and q = (\alpha\times \beta)

So, roots are

( x- (-5)) (x-7)

p = -( -5+7) , q =(-5)(7).

p = -2  and q = -35.

On substituting p and q in equation

x^2+(-2)x-37=0

x^2-2x-37=0

Therefore,x^2-2x-37=0  is the equation of solution -5,7.
