Answer:

y=3x ( the'=' sign is the proportionality sign)

Step-by-step explanation:

x = 1 , 2 , 3 , 4

y = 3 , 6 , 9 , 12

You are multiplying by 3 to get to y

1 x 3 = 3

2 x 3 = 6

3 x 3 = 9

4 x 3 = 12

well the table would look like this

x y

1 3

2 6

3 9

4 12

and the direct variation is y=3x but the constant of variation is k=3

What is the axis of symmetry for f(x) = -3x2 + 18 - 7

solong [7]

The vertex form:

$y=a(x-h)^2+k\\\\(h,\ k)-vertex$

The axis of symetry is x = h.

$y=ax^2+bx+c\to h=\dfrac{-b}{2a}$

We have

$f(x)=-3x^2+18x-7\to a=-3,\ b=18,\ c=-7$

Substitute:

$h=\dfrac{-18}{(2)(-3)}=\dfrac{-18}{-6}=3$

<h3>Answer: x = 3</h3>

Y = x —6x+8 The equation above represents a parabola in the xy-plane. Which of the following equivalent forms of the equation di

forsale [732]

Answer:

$y=(x-4)(x-2)$

Step-by-step explanation:

Consider the given equation

$y=x^2-6x+8$

Factor form of a parabola: It displays the x-intercepts.

$y=a(x-p)(x-q)$ .... (1)

where, a is a constant and, p and q are x-intercepts.

So, we need to find the factored form of the given equation.

Splinting the middle term we get

$y=x^2-4x-2x+8$

$y=x(x-4)-2(x-4)$

$y=(x-4)(x-2)$ .... (2)

On comparing (1) and (2) we get

$p=4,q=2$

It means x-intercepts of the given parabola are 4 and 2.

Therefore, equivalent forms of the equation is y=(x-4)(x-2).

Two parallel lines are crossed by a transversal. What is the value of x? x = 21 x = 28 x = 35 x = 37

DENIUS [597]

Using the definition of vertical angles you can set up the equation 3x+4=115, when solved you get x=37. Hope this helps!

Fudgin [204]

Answer:

Step-by-step explanation:

Statements Reasons

1). 17 - 3(w + 5) = 6(w + 5) - 2w 1). Given

2). 17 - 3w - 15 = 6w + 30 - 2w 2). Distributive property

3). -3w + 2 = 4w + 30 3). Addition property of equality

4). -7w + 2 = 30 4). Subtraction property of equality

5). -7w = 28 5). Subtraction property of equality

6). w = -4 6). Division property of equality
