I believe the answer is 7.18
Answer:
x = all real numbers
Step-by-step explanation:
first you need to solve the first equation to figure out what y is.
4x - y = 2
<em>add y to both sides of the equation</em>
4x = 2 + y
s<em>ubtract 2 from both sides of the equation</em>
4x - 2 = y
now that you know what y is, you can substitute it in the next equation.
3y = 12x - 6
3(4x - 2) = 12x - 6
<em>open the parenthesis </em>
12x - 6 = 12x - 6
<em>subtract 12x from both sides of the equation</em>
-6 = -6
regardless of what x is, -6 will always equal -6.
so, the answer is all real numbers.
Simply plug in x = 4 in to the function
f(4) = 1/3 * 4
f(4) = 4/3
Answer: 6
Explanation:
A <em>constant</em> is a number or term that does not change. Usually it is the term that <em>does not </em>have a variable. In the equation, 6 cannot change. Therefore, the constant is 6
