<span>False. A transformation changes the size, shape, or position of a figure and creates a new figure. So, no, not all transformations require a change in size.</span>

What is the solution of 3(x-1)=2x+5

Tpy6a [65]

3( x - 1 ) = 2 x + 5

Expand 3(x-1) :

3*x - 3 x 1

3 x - 3 = 2 x + 5

Add 3 both sides :

3 x - 3 + 3 = 2 x + 5 + 3

3 x = 2 x + 8

3x - 2 x = 8

x = 8

hope this helps!

Please help, it is a graph question

Cloud [144]

Answer:

$y = \frac{1}{2} x + \frac{1}{2}$

Step-by-step explanation:

choose 2 points to find slope

(1,1) (-3,-1)

$m = \frac{ - 1 - 1}{ - 3 - 1} = \frac{1}{2}$

y-y1 = m(x-x1)

y-1 = 1/2( x-1)

y = 1/2x + 1/2

the vertex of this parabola is (2,-1). When the x-value is 5 the y-value is 0.what is the coefficient of the squared expression

weeeeeb [17]

1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1

Hope could help :)
