1 solution. it can't be 2, and if you solve it, there is a solution, x stays in the equation, so there's 1 solution
        
             
        
        
        
Answer:
(2,3,4,5)
Step-by-step explanation:
The domain are all real number at x-axis
So the answer is option b (2,3,4,5)
 
        
             
        
        
        
Answer:
0
Step-by-step explanation:
since the "b" in y=mx+b ends up being 0, that means that the y intercept is 0, which also means that the x intercept is 0.
 
        
             
        
        
        
Answer:
y = 4x + 14
Step-by-step explanation:
slope-intercept form: y = mx + b
Slope formula: 
To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.
To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:

Simplify:
18 - 14 = 4
1 - 0 = 1

The slope is 4.
To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:
y = mx + b
18 = 4(1) + b
18 = 4 + b
14 = b
The y-intercept is 14. 
Now that we know the slope and the y-intercept, we can write the equation:
y = 4x + 14
 
        
             
        
        
        
Answer: a bigger or equal to 20
Explanation:
2a/5 - 2 _> a/4 + 1
8a/20 - 40/20 _> 5a/20 + 20/20 
8a - 40 _> 5a + 20
3a _> 60
a _> 20
