The answer is probably 57 exchange good luck
Answer:
x = 3
Step-by-step explanation:
15x-3(3x + 4) = 6
Distribute
15x - 9x - 12 = 6
Simplify
6x = 18
Divide
x = 3
The Piecewise -Defined function and how it is graphed is given below..
<h3>What is the explanation of how the
Piecewise -Defined function is graphed?</h3>
Given the function in the attached image,
- The Graph of f(x) = -x + 3 is drawn for x less than 2 because x is bounded.
- The Graph of f(x) = 3 is draw for x greater than and equal to 2 and less than 4 because x is bounded.
- The Graph of f(x) = 4 - 2x is draw for x greater than equal to 4 because x is bounded.
See the attached Graph for better understanding.
- f(x) = -x + 3 is coded purple.
- f(x) = 3 is coded orange.
- f(x) = 4 - 2x is coded green.

Answer:
3) y = 3x
Step-by-step explanation:
a line equation is typically written as
y = ax + b
a is the slope, the inclination of the line. it is defined as ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.
so, e.g. going from (0,0) to (4,12) means
x changes by +4 (from 0 to 4)
y changes by +12 (from 0 to 12)
so, the slope is +12/+4 = 3
and the line equation starts like this
y = 3x + b
now, b is the y-intercept : the y value, where the line intercepts (crosses) the y-axis. in other words, the y value where x = 0.
and we have that right away, as the line goes through (0,0). that IS the y-intercept point. the y value there is 0.
therefore, b=0.
and so the full line equation is
y = 3x
