Answer:

y=-1

Step-by-step explanation:

We get the equation 2x-y=1, and x=0. Since we know the value of x, that it is equal to 0, we can plug this into the equation for x:

2(0)-y=1

From here, we can multiply 2 by 0 and then divide both sides by -1 to isolate y and get what it's equal to.

0-y=1

-y=1

y=-1

Hope this helps!

Leya [2.2K]

Answer:

x = -19/2      y = -33/2

Step-by-step explanation:

x - (3x + 12) = 7

x - 3x - 12 = 7

-2x - 12 = 7

-2x = 19

x = -19/2

x - y = 7

-19/2 - y = 7

-y = 33/2

y = -33/2

Can someone help me with this? Right answer gets brainliest!! :)
Sedbober [7]

I have 2 answers in mind

Answer #1:

\frac{y}{z}

Step-by-step explanation:

quotient means the answer to 2 things being divided so the quotient of y and z would be \frac{y}{z} because there is no numerical value.

Answer #2:

1

Step-by-step explanation:

Usually, when a letter is left by itself in an equation it usually has an invisible one in front of it. so when dividing y by z it would equal 1/1 which is equal to one.

Hope this helps :)

Can someone solve this?
Gemiola [76]

Answer:

B : 4x\sqrt{17}

Step-by-step explanation:

If you divide a rhombus using its diagonals, you get 4 right triangles, whose legs are both 1/2 the length of the diagonals.

This means that the legs of one of those 4 triangles have lengths of 2x/2, and 8x/2, so the legs of one of those triangles x and 4x. This makes the length of one side equal to \sqrt{x^{2} + (4x)^{2}} = \sqrt{17x^2} = x\sqrt{17}. Because all 4 sides are the same length, you multiply this value by 4, and get 4x\sqrt{17}, which is B.

inna [77]

Answer:

12(-3x + 2)

Step-by-step explanation:

-1/2 ( 32x - 40) - (20x - 4) = -16x + 20 - 20x + 4 = -36x + 24 = 6(-6x + 4) = 12(-3x + 2)
