Answer:
Step-by-step explanation:
To determine the inverse of an equation, simply switch the places of the 'x' and 'y' variables. Therefore:
f(x) = -2x + 3
Use 'y' in place of f(x).
y = -2x + 3
Switch the 'x' and the 'y':
x = -2y + 3
Subtract '3' from both sides:
x - 3 = -2y
Divide both sides by '-2':
Simplify:
Answer:
-18.9
Step-by-step explanation:
-25.3 - (-6.4) = -25.3 + 6.4 = -18.9
The key to solving this problem is drawing a rectangle outside the figure and subtracting the reas of the triangles formed from the are of the rectangle. You can look at the attched image if you want a visual.So first let's find the area of the rectangle, the length is 11 and the width is 5 so the area is 55. Now let's find the area of the trinagles. Triangle 1 has sides of 4 and 3 so the area is 6. Triangle 2 has sides of 5 and 5 so the area is 25/2. Triangle 3 has sides of 2 and 5 so the area is 5. Now let's add the area of the triangles up to get 47/2. Now let's subtract 47/2 from 55 to get the area of the figure which is *drumroll*...63/2. that's all.
