The 10^-4 means that the decimal point is 4 places to the left of where it is in 8.25 (if the exponent was positive the decimal point would be to the right). If you move the decimal point 4 places to the left you get an answer of 0.000825 which is 8.25 * 10^-4 in standard form.
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3. 16 is a perfect square and 10 is not a perfect square
U would solve this by subbing in ur answer choices to see which ones make the equation true.
ur answer is : (-1,-8) , (0,-3), (3,12)
4: 28, 5: 40, 6: 54, 7: 70
The equation is always y=mx+b so find where the x,y intercepts are between ur points
