Answer:
area of the shaded figure

To solve 540 = 12z you have to use inverse operation by dividing both sides by 12 to get 45 = z
Answer: Easy, graph and solution
Step-by-step explanation: First what you want to do use the slope intercept form to find the slope and y intercept; -1/2 and y intercept (0,4). Any line can be graphed using 2 points. Select two x values, plug them into the equation to find the corresponding y values. Solution
1.) Step; x and y
Table:
0║4
8║0
- All you had to do is divide 0=-x/2 +4= . (8) For the x intercept you get 8and for y you get 4 because you divided 0=-0/2+4

Since both equations are equal to y, they must equal each other. So set them to equal each other.
28 + 0.05x = 25 + 0.07x (✿ ♥‿♥)
Let's start by subtracting 25 from both sides!
3 + 0.05x = 0.07x (28-25=3, 25-25=0)
Now let's subtract 0.05 from both sides O(≧▽≦)O
3 = 0.02x
We need this x by itself, so let's get rid of it. Do this by divide both sides by 0.02 ( ´_⊃`)
150 = x
So x = 150. Let's test this. Substitute 150 in for x in both equations! \(^○^)人(^○^)/
28+0.05(150) = 25+0.07(150)
28 + 7.5 = 25 + 10.5 (0.05*150=7.5, 0.07*150 = 10.5)
35.5 = 35.5
It works! (ノ◕ヮ◕)ノ*:・゚✧
So x = 150
