Answer:

x= 2

Step-by-step explanation:

so expand the left side of the equation

9x+9= 25+x

and then group like terms( subtract 9 from both sides and also do same with x.

9x-x= 25-9

8x= 16

divide by 8 on both sides.

x=2

Alik [6]

Answer:

  • y = -3x + 7

Step-by-step explanation:

<u>Use points on the graph:</u>

  • (0, 7) and (2, 1)

<u>Find the slope:</u>

  • m = (1 - 7)/ 2 = -3

<u>The y-intercept is known b = 7, so the equation is:</u>

  • y = mx + b
  • y = -3x + 7

Which function has a vertex at (2, 6)?
vlabodo [156]

The function f(x) = 2|x – 2| + 6 has a vertex at (2, 6) option second is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function that has vertex at (2, 6)

The options are:

f(x) = 2|x – 2| – 6

f(x) = 2|x – 2| + 6

f(x) = 2|x + 2| + 6

f(x) = 2|x + 2| – 6

As we know the vertex form of a quadratic function is given by:

f(x) = a(x - h)² + k

Similarly, mod function  can be expressed as:

m(x) = a|x - h| + k

Here (h, k) is the vertex of a function.

In the function:

f(x) = 2|x – 2| + 6

The vertex of the function is (2, 6)

Thus, the function f(x) = 2|x – 2| + 6 has a vertex at (2, 6) option second is correct.
