Y=-4x + 2 y = -x - 1

Mathematics
1 answer:
USPshnik [31]3 years ago
7 0

Hey there! I'm happy to help!

We have two values for y in terms of x. We can now create an equation to solve for what x is.

-4x+2=-x-1

We add x to both sides

-3x+2=-1

We subtract 2 from both sides.

-3x=-3

We divide both sides by -3.

x=1

Now, we can plug our x into one of the original equations and then solve for y!

y= -4+2

y=-2

We can also test this with the other.

y= -1-1

y=-2

Therefore, our solution is (1, -2), or x=1 and y=-2.

I hope that this helps!

Which of the equations below could be the equation of this parabola?
Mademuasel [1]

Answer:

Option B: y = -\frac{1}{2} x^2

Step-by-step explanation:

The parabola has its concavity downwards, so we need a function in the model:

y = ax^2 + bx + c

With a negative value of 'a'

The vertex is (0,0), so we have that:

0 = 0a + 0b + c

c = 0

The x-coordinate of the vertex is given by the equation:

x\_vertex = -b/2a

-b/2a = 0

b = 0

So we have a function in the model:

y = ax^2

With a < 0

The only option with this format is B:

y = -\frac{1}{2} x^2

Write an equation that gives the proportional relationship of the graph.
labwork [276]

Answer:

C

Step-by-step explanation:

A proportional graph is a line. Every line has a slope. The slope is found by subtracting two points as a ratio. The line has points (0,0) and (2,6).

6-0 = 6

2 -0 = 2

The ratio is vertical over horizontal so 6/2 = 3.

The equation is y = 3x.
