Answer:

x=2

Step-by-step explanation:

2x+x+5= 4x+3

first combine like terms, so add 2x and x which is 3x

3x+5= 4x+3

Then subtract 3x from both sides 3x-3x+5= 4x-3x+3

5= x+3

subtract 3 on both sides 5-3= x+3-3

2=x

Answer Check:

substitute x for 2

2(2)+2+5=4(2)+3

multiply 2 times 2 and add 2 which is 6 and 4 times 2 which is 8

4+5= 8+3

add the number to together to see if the two equations are equal

11 = 11

the answer is right

If g(f) the inverse of

tiny-mole [99]

Answer:

$g(x)=\frac{x}{4}-3$

Step-by-step explanation:

we have

$f(x)=4x+12$

Find the inverse

Let

y=f(x)

$y=4x+12$

Exchange the variables (x for y and y for x)

$x=4y+12$

Isolate he variable y

subtract 12 both sides

$4y=x-12$

divide by 4 both sides

$y=\frac{x}{4}-3$

Let

g(x)=y

$g(x)=\frac{x}{4}-3$ ---> inverse of the function f(x)

-BARSIC- [3]

Answer:

Step-by-step explanation:

Vertex-form equation for vertical parabola:

y = a(x-h)² + k

with

vertex (h,k)

axis of symmetry: x = h

Apply your equation

y = 3x² + 18

vertex (0,18)

axis of symmetry: x = 0
