System of equations

nalin [4]

Answer:

The solution of the system of equations is the point (-3,0)

Step-by-step explanation:

we have

$-3x+y=9$ -----> equation A

$2x-y=-6$ -----> equation B

Adds equation A and equation B

$-3x+y=9\\2x-y=-6\\------\\-3x+2x=9-6\\-x=3\\x=-3$

Find the value of y

$-3(-3)+y=9$

$9+y=9$

$y=9-9=0$

The solution of the system of equations is the point (-3,0)

What value for C will make the expression a perfect square trinomial x2-7x+c

Tom [10]

Answer:

The value of c is 12.25

Step-by-step explanation:

we know that

A perfect square trinomial is of the form

$(x-a)^{2}=x^{2}-2ax+a^{2}$

In this problem we have

$x^{2}-7x+c$

equate the equations

$x^{2}-7x+c=x^{2}-2ax+a^{2}$

we have

the following equations

$-7x=-2ax$ -----> equation A

and

$c=a^{2}$ -----> equation B

<u>Solve the equation A</u>

$-7x=-2ax$

$7=2a$

$a=3.5$

<u>Solve the equation B</u>

$c=a^{2}$

$c=3.5^{2}=12.25$

therefore

$(x-3.5)^{2}=x^{2}-7x+12.25$

The value of c is 12.25
