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!

Answer:

y = -1

Step-by-step explanation:

2x - y = 1

x = 0

y = ?

2(0) - y = 1

-y = 1

y = -1

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

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:

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.
