A) What equation is used to find the vertex form of a parabola with the vertex (h, k)?

1 answer:

4 0

Y=ax2+bx+c . In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .

For what value is x+4/5x-9 undefined?

pochemuha

Hello from MrBillDoesMath!

Answer: x = 9/5

Discussion :

The quotient is undefined when the denominator = 0. i.e. 5x - 9 = 0

5x - 9 = 0

5x = 9 (add 9 to both sides)

x = 9/5 (divide both sides by 5)

547% of what number is 366.49

Rom4ik [11]

Answer:

Step-by-step explanation:

To solve this question ( that is to know the number), we must interpret the statement mathematically. Let the unknown number be T then,

547% of T = 366.49

547 * T/100 = 366.49

547T = 36646

T = 36649/547

= 67

It means that 547% of 67 gives 366.49

$\left \{ {-3x-2y = -6} \atop {-3x+2y=18} \right. \left \{ {-6x=12} \atop {-3x+2y=18} \right. \left \{ {x=-2} \atop {y=6} \right.$

The answer: ( x ; y ) = ( -2 ; 6 )

Ok done. Thank to me :>
