Answer:
khan academy
Step-by-step explanation:
khan academy its something that I usually use to study algebra and Geometry this page includes videos with a really good information.
After you type in your equations and hit graph you notice that, if you are in the standard window, your parabola is cut off so you have to choose your "window" button to change the viewing window to see the whole graph. Then you would use your 2nd button and "trace" and "intersect" to find the points of intersection of the 2 graphs. The first point is at (-.90901, 16.81812) and the second point is at (5.9090909, 3.1818182). Graphing calculators are quite amazing!
Working with fractions, huh? They are not as hard as you may think.
Just think:
1/4 = 2/8
3/4= 6/8
So...
9 3/4 = 9 6/8
Step 2.
9 + 1 = 10
6/8 + 1/8 = 7/8
Step 3
10 and 7/8
Step 4
Simplest answer
10 7/8,
(can't get more simplified than that)
Hope this helps! :)
38. Slice it by forming a trapezoid on top, a 4x4 square in the middle, and then a triangle at the bottom.
39. Slice it by forming two separate triangles on top, a right triangle, and a scalene triangle. The last figure at the bottom should be another trapezoid with a height of 2.
