If the equation is given in factored form and the roots are real, then you can identify the x-coordinate of the vertex by averaging the 2 root values.  For example, if the roots are -2 and 5, the x-coord. of the vertex is (-2+5)/2, or 3/2.

Once you have this x value, subst. the value into the given equation to calculate y.  Then write the vertex as (x,y).

Question 10 Express 40 as a product of prime factors​
Step2247 [10]

Answer:

2 x 2 x 2 x 5

Step-by-step explanation:

The first few prime numbers:  {2, 3, 5, 7, 11, 13, 17, 19}

One way to start is to divide by the first prime until you can't do that any more, then try the next prime and so on until all the numbers in your list are prime.

40 = 2(20)  divide 20 by 2 again

40 = 2(2)(10)  divide 10 by 2 again

40 = 2(2)(2)(5) stop--all factors are prime.

Pls help me that would be great
omeli [17]
No. No. It is not linear because the slope has to be able to be plugged in to any x, y coordinates and be placed on the line.
