How are the real solutions of a quadratic equation related to the graph of the quadratic function?
Anika [276]
The solutions you get when you solve the formula are the corresponding y coordinates to your x value. So say a point on your graph is (2,3). The first number is x and the second is y. (x,y). The number you plug into your function is x,or in this case: 2. The solution to the equation when the x value is plugged in is y, or 3. Therefore, giving you a point on your graph.

Choose the correct simplification of the expression (2x2y6z5)(5x4y5z3).
erastovalidia [21]

Answer:

The correct option is 4.

Step-by-step explanation:

The given expression is

(2x^2y^6z^5)(5x^4y^5z^3)

Simplify the given expression.

(2x^2y^6z^5)\times (5x^4y^5z^3)

(2\times 5)(x^2x^4)(y^6y^5)(z^5z^3)

10x^{2+4}y^{6+5}z^{5+3}                  [\because x^mx^n=x^{m+n}]

10x^6y^{11}z^8

Therefore correct option is 4.

HELP PLEASE<br> Solve for x:<br><br> x - 8 = 3x - 2<br><br><br> -3<br><br> -2<br><br> 3<br><br> 1
creativ13 [48]

Answer:

x=3

Step-by-step explanation:

You add the eight to both sides, leaving x on the left and making the -2 a 6 on the right.

Now you have x= 3x-6

Add the six to the right, giving you 6+x=3x

Subtract the x from the left and right. you get 6=2x

Divide 6 by 2 to get x.
