WHat is the ellimination of x-y=-2 and 7x+2y=-5
nydimaria [60]
<span>This question is from textbook
</span><span>1. Solve by substitution or elimination method: 3x – 2y = 26 -7x + 3y = -49 Eliminate x: 3x – 2y = 26 -7x + 3y = -49 the coefficients of x are 3 and -7. Ignoring signs temporarily they are 3 and 7. The least common multiple of 3 and 7 is 21. If we multiply the first equation through by 7, there will be a 21x where the 3x is now. If we multiply the second equation by 3, there will be a -21x where the -7x is. And 21x and -21x will cancel out when we add equals to equals. So let's multiply the first equation through by 7 and the second equation through by 3: 7[ 3x – 2y = 26] 3[-7x + 3y = -49] 21x - 14y = 182 -21x + 9y = -147 Draw a line underneath and add equals to equals vertically: 21x - 14y = 182 -21x + 9y = -147 ------------------- 0x - 5y = 35 -5y = 35 Divide both sides by -5 y = -7 Eliminate y: 3x – 2y = 26 -7x + 3y = -49 the coefficients of y are -2 and 3. Ignoring signs temporarily they are 2 and 3. The least common multiple of 2 and 3 is 6. If we multiply the first equation through by 3, there will be a -6y where the -2y is now. If we multiply the second equation by 2, there will be a 6y where the 3y is. And -6y and 6y will cancel out when we add equals to equals. So let's multiply the first equation through by 3 and the second equation through by 2: 3[ 3x – 2y = 26] 2[-7x + 3y = -49] 9x - 6y = 78 -14x + 6y = -98 Draw a line underneath and add equals to equals vertically: 9x - 6y = 78 -14x + 6y = -98 ------------------- -5x + 0y = -20 -5x = -20 Divide both sides by -5 x = 4 So the solution is (x,y) = (4,-7) ==================================== 2. Solve by substitution or elimination method: 4x – 5y = 14 -12x + 15y = -42 Eliminate x: 4x – 5y = 14 -12x + 15y = -42 The coefficients of x are 4 and -12 Ignoring signs temporarily they are 4 and 12. The least common multiple of 4 and 12 is 12. If we multiply the first equation through by 3, there will be a 12x where the 4x is now. We don't need to do anything to the second equation for the 12x and the -12x will cancel out when we add equals to equals. So let's multiply the first equation through by 7 and leave the second equation as it is: 3[ 4x – 5y = 14] -12x + 15y = -42 12x - 15y = 42 -12x + 15y = -42 Draw a line underneath and add equals to equals vertically: 12x - 15y = 42 -12x + 15y = -42 ------------------- 0x + 0y = 0 As you can see, any number may be substituted for x and y and that will always be true, since you'll always get 0 on the left and that will always give 0 and 0 will always equal to 0. So there are infinitely many solutions. This sort of system is called "dependent". We need go no further. We just state that the system is dependent and has INFINITELY MANY solutions. =============================================== 3. Solve by substitution or elimination method: -2x + 6y = 1 10x – 30y = -15 Eliminate x: -2x + 6y = 1 10x – 30y = -15 The coefficients of x are -2 and -10 Ignoring signs temporarily they are 2 and 10. The least common multiple of 2 and 10 is 10. If we multiply the first equation through by 5, there will be a -10x where the -2x is now. We don't need to do anything to the second equation for the 10x and the -10x will cancel out when we add equals to equals. So let's multiply the first equation through by 5 and leave the second equation as it is: 5[ -2x + 6y = 1] 10x - 30y = -15 -10x + 30y = 5 10x - 30y = -15 Draw a line underneath and add equals to equals vertically: -10x + 30y = 5 10x - 30y = -15 ------------------- 0x + 0y = -10 </span>

N is an odd number.
nikitadnepr [17]

Answer:

True:

D.

E.

F

Step-by-step explanation:

First, you should know that the square of any odd number is also odd.

The easiest way to go about this is to plug in an odd number for n. Lets use 3:

Plug 3 into A:

3^{2} -1=9-1=8

Plug 3 into B:

3(3-1)=9-3 = 6

Plug 3 into C:

(3-2)^{2} = 2^{2}  = 4

Plug 3 into D:

3^{2} +2 = 9+2=11

Plug 3 into E:

3(3-2) = 9-6 = 3

Plug 3 into F:

(3-2)^{2}=1^{2}  =1
