Factor by grouping:
erma4kov [3.2K]
The idea is to group up the terms into two groups, factor each group and then factor out the overall GCF

2x - 18 + xy - 9y
(2x - 18) + (xy - 9y)
2(x - 9) + (xy - 9y)
2(x - 9) + y(x - 9)
(2 + y)(x - 9)
(x - 9)(2 + y)

Out of 10 students, 2 will be chosen to ride in a car instead of a van on an upcoming field trip. Which statement best describes
Rudiy27

Answer:

D

Step-by-step explanation:

Firstly, since it is a selection question, we shall be using a combination approach.

So here we are trying to select the best answer that describes that 2 out of 10 students are selected.

Let’s consider the scenario below;

selecting r out of n can be resolved using the combination nCr

= n!/(n-r)!r!

Now in this case, our n = 10 and r = 2.

Thus, 10C2, we have ;

10!/(10-2)!2! = 10!/8!2! = (10 * 9 * 8!)/8!2! = (10 *9)/2! = 90/2 = 45

Thus, 10C2 = 45

Here, the order of selection does not matter as we can select in random fashion. This makes option D correct

PLEASE HELP!! Identify the minium value of the function
timama [110]
Because this is a positive parabola, it opens upwards, like a cup, and the vertex dictates what the minimum value of the function is.  In order to determine the vertex, I recommend completing the square.  Do that by first setting the function equal to 0 and then moving the 9 to the other side by subtraction.  So far: x^2+6x=-9.  Now, to complete the square, take half the linear term, square it, and add that number to both sides.  Our linear term is 6.  Half of 6 is 3 and 3 squared is 9.  So add 9 to both sides. x^2+6x+9=-9+9.  The right side reduces to 0, and the left side simplifies to the perfect square binomial we created while completing this process.  (x+3)^2=0.  Move the 0 back over and the vertex is clear now.  It is (-3, 0).  Therefore, 0 is the minimum point on your graph.  The first choice above is the one you want.

What is the solution to the equation below? <br> Vx + 3 = x - 3 <br> A. 3<br> B. 6<br> C. 5<br> D. 4
kherson [118]

Answer:

6

Step 1: Solve Square Root

Vx+3=x-3

x+3=(x-3)^2 (squared both sides)

x+3=x^2-6x+9

x+3-(x^2-6x+9)=0

(-x+1)(x-6)=0 (factor left side of equation)

-x+1=0 or x-6=0

x=1 or x=6

When you plug it in to check

1 (Doesn't Work)

6 (Work)

Therefore, 6 is your solution.
