A student draws a geometric shape where all of the sides are different lengths. which of the following geometric shapes could the student have drawn?
a. rhombus
These are the answers to problems 29 and 30:
29. C
30. C
7x + 5y = 19
<u>-7x - 2y = -16</u>
<u>3y</u> = <u>3</u>
3 3
y = 1
7x + 5y = 19
7x + 5(1) = 19
7x + 5 = 19
<u> -5 - 5</u>
<u>7x</u> = <u>14</u>
7 7
x = 2
(x, y) = (2, 1)
The method would be a elimination method (the answer is C).
