12x a y b ÷ (-6x a y) quotient.

Nady [450]

If that is what it looks like it is, 12 divided by -6 is -2, the a's cancel out, the y's cancel out, and you're left with -2b. I'm not sure what else this could be.

Please help me, I need an answer as soon as possible.

Lemur [1.5K]

Answer:

$\huge\boxed{\sf x = \pm \sqrt{7} }$

Step-by-step explanation:

<u>Given function:</u>

$f(x)=x^2-7$

<u>We can also write it as:</u>

$y =x^2-7$

x-intercept is the point where y = 0

Put y = 0 in the above equation

$0=x^2-7\\\\Add \ 7 \ to \ both\ sides\\\\7 = x^2\\\\Take \ sqrt \ on \ both \ sides\\\\\pm \sqrt{7} =x\\\\x = \pm \sqrt{7} \\\\\rule[225]{225}{2}$

Select the true statement. A) (a2)4 = a6 B) (a2)4 = a2 C) (a2)4 = a8 D) (a2)4 = 2a

Nonamiya [84]

Das test your knowlege of this exponential law
$(x^m)^n=x^{mn}$

so

$(x^2)^4=x^{(2)(4)}=x^{8}$

C is the correct answer

Solve the following system: 5x + 4y = 6 -2x – 3y = -1

yanalaym [24]

Answer:

$\left \{ {{y=-1} \atop {x=2}} \right.$

Step-by-step explanation:

$\left \{ {{5x+4y=6} \atop {-2x-3y=-1}} \right. \left \{ {{10x+8y=12} \atop {-10x-15y=-5}} \right. \left \{ {{-7y=7} \atop {-10x-15y=-5}} \right. \left \{ {{y=-1} \atop {-10x-15y=-5}} \right. \left \{ {{y=-1} \atop {-10x+15=-5}} \right. \left \{ {{y=-1} \atop {-10x=-20}} \right. => \left \{ {{y=-1} \atop {x=2}} \right.$
