It's a linear function.
y = 2x + 4 - it's a slope-intercept form
slope m = 2
y-intercept = 4
The slope m = 2 > 0, thereofre the function is increasing (going to infinity).
Calculate the value of function for x = 3:
y = 2(3) + 4 = 6 + 4 = 10.
Therefore we have answer:
<h3>Range is (10, ∞).</h3>
Answer: x=4
Step-by-step explanation:
Simplifying
(14x + -15) + 139 = 180
Reorder the terms:
(-15 + 14x) + 139 = 180
Remove parenthesis around (-15 + 14x)
-15 + 14x + 139 = 180
Reorder the terms:
-15 + 139 + 14x = 180
Combine like terms: -15 + 139 = 124
124 + 14x = 180
Solving
124 + 14x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-124' to each side of the equation.
124 + -124 + 14x = 180 + -124
Combine like terms: 124 + -124 = 0
0 + 14x = 180 + -124
14x = 180 + -124
Combine like terms: 180 + -124 = 56
14x = 56
Divide each side by '14'.
x = 4
Simplifying
x = 4

6x + (x + -2) = 180
Reorder the terms:
6x + (-2 + x) = 180
Remove parenthesis around (-2 + x)
6x + -2 + x = 180
Reorder the terms:
-2 + 6x + x = 180
Combine like terms: 6x + x = 7x
-2 + 7x = 180
Solving
-2 + 7x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 7x = 180 + 2
Combine like terms: -2 + 2 = 0
0 + 7x = 180 + 2
7x = 180 + 2
Combine like terms: 180 + 2 = 182
7x = 182
Divide each side by '7'.
x = 26
