Algebra Test #1

For the first part of the test we had to write the following expressions in words..

- 3x+8 : Three times a number and eight
- 7x+5x : Seven times a number and five times a number
- 5(x+8) : Five times the sum of a number and eight
- 8-3x : Eight decreased three times a number

5. 9 centimeters less than three fourts of length x : 3/4x-9

6. Seven decreased by four times a number : 7-4n

7. 9 less than 3 times a number : 9-3x 8. four more than eight times a number : 8x+4

6. Seven decreased by four times a number : 7-4n

7. 9 less than 3 times a number : 9-3x 8. four more than eight times a number : 8x+4

For the second part of the test we had to make a t-chart, graph and figure out the algebraic equation for the following problem ..

This is my T-chartThe patter : x = Figure number, Starting with one going up by one.

y = Number of tiles, starting with four and adding three each time.

Here is my Graph
