Answer:

x=2

Step-by-step explanation:

The parallel lines divide the transversal into proportional segments that is

\frac{x + 4}{13.5} =  \frac{4}{9}

(cross multiply)

9(x+4)=54 (divide by both sides by 9)

x+4=6 (subtract 4 from both sides)

x=2

As we know y=3/4x-3
Let's put it in the second equation
3/4x-3=1/4x+1
3/4 x -1/4 x = 1+3
2/4 x = 4
X= 4*4/2
x=8
Put x= 8 in first equation
y= 3/4 *8 -3
y=6-3
y=3
Check the answer
3=3/4 *8 -3
3=6-3
3=3
Correct
So(y, x) = (3,8)
Because x=8 and y=3

How does the graph of g(x) = (x - 3)^3 + 4 compare to the parent function f(x)=x^3 ?​
masha68 [24]

Answer:

f(x) has moved:

4 units in the positive y direction i.e upwards

3 units in the positive x direction

Step-by-step explanation:

to get g(x), f(x) has undergone the following transformations

f(x) = x³

f1(x) = x³ + 4      (translation of 4 units in the positive y direction i.e upwards)

f2(x) = g(x)  = (x-3)³ + 4 (translation of 3 units in the positive x direction i.e towards the right)
