Answer:

Step-by-step explanation:

Substitution method:

y= -2x + 2

x - 2y = 6

so y = (-2x + 2)

Substitute into y

Hence x - 2y = 6 is:

x + 2x +2 = 6 (+2x because there was - in the equations so -×- = +)

3x + 2=6

Then bring 2 to the other side so

3x = 6-2

3x = 4

x = 3/4 or 0.75

To find y :

y= (-2 × 3/4) + 2

y = -1.5 +2

y = 0.5

That's all I can do for now!

garik1379 [7]

Answer:

Step-by-step explanation:

So you just need to find 7 + what is equal to 63. To find this we have to do inverse operation, which means the opposite operation. So, we do 63-7 which is equal to 56. Therefore, the solution to the equation, or x is equal to 56 (C).

Hope this helps !!

Minimize Q=3x2+3y2, where x+y=6.

weeeeeb [17]

Answer:

$+(x + y) {}^{2} = 6 {}^{2} \\ x {}^{2} + 2xy + y {?}^{2} = 36$

$x {}^{2} + y {}^{2} = 36 - 2xy$

$q = 3(x {}^{2} + y {}^{2} )$

$q = 3(36 - 2xy) = 108 - 6xy$

If the length of a rectangle is 2x + 4 and the width is x - 2. write

Bess [88]

Answer:

P = 6x +4

Step-by-step explanation:

Use the given values in the formula for the perimeter of a rectangle:

P = 2(L +W)

You have ...

L = 2x +4

W = x -2

So, the perimeter is ...

P = 2((2x +4) +(x -2)) = 2(3x +2)

P = 6x +4

The perimeter of the rectangle is 6x+4.
