What are the zeros of the polynomial x2+4x-12

1 answer:

3 0

Hi,
$x^2+4x-12=0\\

\Rightarrow\ x^2+6x-2x-12=)0\\
\Rightarrow\ x(x+6)-2(x+6)=0\\
\Rightarrow\ (x+6)(x-2)=0\\

\boxed{\Rightarrow\ x=-6\ or\ x=2}\\

Ostrovityanka [42]

Answer:

RM3,500

Step-by-step explanation:

Salary=RM375 per week

5% commission per week

If she target a minimum of RM 550.

Let x=minimum Sales

RM550=RM375 + 5% of x

RM550=RM375 + 0.05x

RM550 - RM375=0.05x

RM175=0.05x

Divide both sides by 0.05

RM175/0.05=0.05x/0.05

RM3,500=x

For Azila to earn a minimum of RM550 in a week, her salary will be RM375 plus 5% commission on the sales of RM3,500 value of product.

Check:

5% of RM3,500

=0.05*3,500

=RM175

Answer:

$\Huge\boxed{z$

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

$\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25$

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25
