Answer:
120
Step-by-step explanation:
expand and calculate
10x9x8x7!/(10-3)!x3!
10x9x8x7!/7!x3!
reduce
10x9x8x<u>7</u>!/<u>7</u>!x3!
10x9x8/3!
Calculate the product
10x9x8/3!
Now Cacluate the factorial
720/3!
720/6
reduce

The sequence of operations is multiply the <u>first equation</u> by –3 and add the result to the <u>second equation</u> to eliminate y and solve for x. The correct option is - b)
<h3>Solving a system of equations by Elimination </h3>
From the question, we are to determine the sequence of operations that would produce the correct x- or y-value of the solution to the given system of equations
The given systems of equations are
2x+y=9
x+3y=-13
- First, multiply the first equation by -3
That is
-3 × (2x+y=9)
-6x-3y=-27
- Now, add to the second equation
-6x-3y=-27
+(x+3y=-13)
-----------------
-5x = -40
Thus, we can solve for x
These sequence of operations will enable us to eliminate y and solve for x
Hence, the sequence of operations that would produce the correct x- or y-value of the solution to the system of equations is multiply the <u>first equation</u> by –3 and add the result to the <u>second equation</u> to eliminate y and solve for x. The correct option is - b)multiply the first equation by –3 and add the result to the second equation to eliminate y and solve for x

Answer:
C. 1
Step-by-step explanation:
We can see that each box in the grid is one unit.
We count one box to the right on the horizontal axis and 4 boxes down on the vertical axes to obtain the components of vector v.
See graph in attachment.
Therefore the components of vector v is
.
The length of the x component is 1 unit
Hence the correct answer is C.
Answer:
28
Step-by-step explanation:
27 x 2 = 54
13 x 2 = 26
54 - 26 = 28
