The below solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the triangle area. Find the area of a triangle having the base b = 18 & height h = 12 cm?
The answer would be four and two over seven or 4 2/7
y = | x + 5 | - 4
You subtract 4 outside the abs val to move the graph down.
You add 5 inside the abs val to move the graph left. (Inside translations are the opposite of what you'd expect.)
Answer:
AB = 9
Step-by-step explanation:
Here is a simple case of a proportion.
We see that:
3:4
x:12
what can we do to make 4 into 12?
we multiply it by 3
so we do the same to 3
3*3=9
