A scale factor of 3 means that the new shape is three times the size of the original. To calculate the Scale Factor, we use the following: You can get the 'big' and 'small' from the corresponding sides on the figures. So just get your # and multiply it by 3
If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.
If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)
If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
Answer:
7:4
Step-by-step explanation:
42:24
divide both sides by 6
7:4
Answer: x = 6
Step-by-Step Explanation:
=> -9x + 2x + 32 = -10
= -7x + 32 = -10
= -7x = -10 - 32 = -42
=> x = -42/-7 = 42/7 = 6
Therefore, x = 6
