Answer:
something like this?
the top one is valid when x-4 >0
the bottom one is valid when x-4<0
Step-by-step explanation:
absolute value |x-4|
means that in case x-4 is negative, we will use -(x-4)
if it's positive we use x-4
let's find the solution (where the original inequality is true)
negative case:
-(x-4)<9 -x+4 < 9 -x < 5 x>-5
positive case:
x-4 < 9 x < 13
to satisfy both conditions -5 < x < 13
The lengths of the three pencils form a right-triangle, and the two-step problem is:
- 6^2 + 8^2 = 10^2
- 100 = 100
<h3>How to write the two-step problem</h3>
The lengths of the pencils are given as:
6cm, 8cm and 10cm
Using the Pythagoras theorem, we have:
6^2 + 8^2 = 10^2
Evaluate the exponents
100 = 100
Hence, the lengths of the three pencils form a right-triangle

Answer:
-24
Step-by-step explanation:
f(x) = 3x^3 -12x^2
f(2) = 3 * (2)^3 - 12 (2)^2
= 3 (8) - 12 (4)
= 24 - 48
= -24
