Answer:

x =  - 5

or

x = 2

Step-by-step explanation:

We want to solve ;

{12}^{ {x}^{2}  + 5x - 4}  =  {12}^{2x + 6}

We equate the exponents, because is the same on both sides.

{x}^{2}  + 5x - 4 = 2x + 6

We group and rewrite in standard form to get:

{x}^{2}  + 5x - 2x - 4 - 6 = 0

{x}^{2}  + 3x- 10= 0

{x}^{2}  - 2x + 5x - 10 = 0

x(x - 2) + 5(x - 2) = 0

(x + 5)(x - 2) = 0

x =  - 5 \: or \: x = 2

The equation y=21.2x represents Austin's earnings in dollars and cents, y,
Talja [164]

Given:

The equation is

y=21.2x

Where, y is earnings for working in dollars and cents and x is the number of working hours.

To find:

The rate of change.

Solution:

The slope intercept form of a linear function is

y=mx+b          ...(i)

Where, m is the slope and b is the y-intercept.

We have,

y=21.2x            ...(ii)

On comparing (i) and (ii), we get

m=21.2

Therefore, the rate of change is 21.2 dollar and cents per hour.

Two functions are given below: f(x) and h(x). State the axis of symmetry for each function and explain how to find it. f(x) h(x)
BartSMP [9]

Answer:

Axis of symmetry for the functions f(x) and h(x) are x = 4 and x = -2 respectively.

Step-by-step explanation:

Function f(x) = -2(x - 4)² + 2

Vertex of the graph → (4, 2)

Since line of symmetry of the graph is defined by the x-coordinate of the vertex.

Therefore, x = 4 will be the line of symmetry of the function 'f'.

Second function 'h' has been given in the graph.

Vertex of the function from the graph → (-2, 2)

Therefore, line of symmetry will be x = -2
