I think the answer is (2,2)
GarryVolchara [31]3 years ago

Answer:

D:) (2,2,) is the Answer

Step-by-step explanation:

Solve the following system:


{X - 2 Y = -2 | (equation 1)


{3 X - 2 Y = 2 | (equation 2)



Swap equation 1 with equation 2:


{3 X - 2 Y = 2 | (equation 1)


{X - 2 Y = -2 | (equation 2)



Subtract 1/3 × (equation 1) from equation 2:


{3 X - 2 Y = 2 | (equation 1)


{0 X - (4 Y)/3 = (-8)/3 | (equation 2)



Multiply equation 2 by -3/4:


{3 X - 2 Y = 2 | (equation 1)


{0 X+Y = 2 | (equation 2)



Add 2 × (equation 2) to equation 1:


{3 X+0 Y = 6 | (equation 1)


{0 X+Y = 2 | (equation 2)



Divide equation 1 by 3:


{X+0 Y = 2 | (equation 1)


{0 X+Y = 2 | (equation 2)



Collect results:


Answer:  {X = 2 , Y = 2

Find the average rate of change for the given function from x = 1 to x = 2.
Nadusha1986 [10]

Answer:

2

Step-by-step explanation:

The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.

So we are going to need to corresponding y coordinates.

What y corresponds to x=1? y=3

What y corresponds to x=2? y=5

So we have the ordered pairs (1,3) and (2,5).

Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.

(2 , 5)

-(1  , 3)

-----------

1      2

The average rate of change is 2/1 or just 2.

Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.

Find four consecutive even integers so that the sum of the first three is 2 more than twice the fourth
scoundrel [369]

Answer:

The numbers are : -20,-18,-16,-14

Step-by-step explanation:

Let 1st even integer be =x

So, next consecutive even integer would be =x+2

3rd consecutive even integer would be =x+4

4th consecutive even integer would be =x+6

Sum of first three integers would be =x+x+2+x+4=3x+6

It says sum of the first three is 2 more than twice the fourth,

So we have

3x+6=2+4(x+6)

using distribution to simplify.

3x+6=2+(4\times x)+(4\times6)

3x+6=2+4x+24

3x+6=4x+26

Subtracting 4x from both sides

3x+6-4x=4x+26-4x

-x+6=26

Subtracting 6 from both sides

-x+6-6=26-6

-x=20

∴ x=-20

So first integer =-20

2nd integer  =-20+2=-18

3rd integer =-18+2=-16

4th integer  =-16+2=-14

So, the numbers are : -20,-18,-16,-14
