4x-8=4x-6

4x-2=4x  add 6 to both sides

-2=x subtract 4x from both sides

4x-8=2(2x-3)
Use distributive property for 2(2x-3)
4x-8=2*2x-2*3
4x-8=4x-6
Add 8 to each side
4x-8+8=4x-6+8
4x=4x+2
Subtract 4x to each side
4x-4x=4x+2-4x
0x=2
Divided 0 to each side
0x/0=2/0
x=undefined. As a result, there is no solution to this equation. Hope it help!

What does the transformation f(x) --> -f(x) do to the graph of f(x)
mixer [17]

Answer: D) Reflect over x-axis

=======================================================

Explanation:

When we do this type of reflection, a point like (1,2) moves to (1,-2).

As another example, something like (5,-7) moves to (5,7)

The x coordinate stays the same but the y coordinate flips in sign from positive to negative, or vice versa.

We can say that (x,y) \to (x,-y) as a general way to represent the transformation. Note how y = f(x), so when we make f(x) negative, then we're really making y negative.

If we apply this transformation to every point on f(x), then it will flip the f(x) curve over the horizontal x axis.

There's an example below in the graph. The point A(2,8) moves to B(2,-8) after applying that reflection rule.

Graph a parabola whose vertex is at (3,5)(3,5)left parenthesis, 3, comma, 5, right parenthesis with yyy-intercept at y=1y=1y, eq
Rudik [331]

Using the given information we found that the equation of the parabola is:

y = (-4/9)*(x - 3)^2 + 5

And its graph is below.

<h3>How to get the equation of the parabola?</h3>

For a parabola with vertex (h, k), the equation is:

y = a*(x - h)^2 + k

Here the vertex is (3, 5), so the equation is:

y = a*(x - 3)^2 + 5

And the y-intercept is y = 1, this means that:

1 = a*(0 - 3)^2 + 5

1 = a*9 + 5

1 - 5 = a*9

-4/9 = a

So the parabola is:

y = (-4/9)*(x - 3)^2 + 5

And its graph is below.

A fraternity charged $2.00 admission for dudes and $1.00 for ladies for their finals week bash. The fraternity made $100.00 and
SVETLANKA909090 [29]
Given : 2D + 1L = 100,
And D + L = 70

This is a simultaneous equation can be solved as follows

2D + L = 100
- D - L = -70
————————————-
D - 0 = 30


i.e D (number of dudes) = 30

Therefore, since we already know the fraternity sold 70 tickets in total,

70 -30 = 40 (the number of ladies attended)
