Answer
-sqrt(18)<x<sqrt(18)
Step-by-step explanation:
- Factorise:(x-sqrt(18))(x+sqrt(18))<0
- Critical values:-sqrt18 and sqrt18
- Use number line or graphical method

Answer:
y= 8x+1 (0,1) y=6x+3 (0,1)
= 8×0+1 =6×0+3
y = 1 =3
Step-by-step explanation:
= 8×1+1 (1,9) =6×1+3 (1,9)
y=9 =9
=8×4+1 (4,14) =6×4+3 (4,14)
y=33 =27
=8×2+1(2,4) =6×2+1 (2,4)
y=17 =13
By using any two of the points in the table, we will see that the slope is -2.
<h3>
How to get the slope for the linear relationship?</h3>
A general linear relationship is:
y = a*x + b
Where a is the slope and b is the y-intercept.
Remember that if the line passes through (x₁, y₁) and (x₂, y₂), the slope is:

Here we can use the first two points on the table:
(-4, 11) and (2, -1), so the slope is:

Then the slope of the line is -2.
