50,000 because to make 5 x 10^4 a normal integer, you need to move the decimal to the right 4 places, or add 4 zero's onto the 5.
You can choose the coordinates of any two points on the vertical line where x=5.
So for the coordinates, you need a y value for both. Since the points have to be on that line, you already know that the x value has to be 5.
Answer: she would get 100%
Step-by-step explanation: every correct question u get 5 points so 20 * 5 = 100
Answer:
(5, -2)
Step-by-step explanation:
x - 7 = -2x + 8
add 2x to both sides
x - 7 + 2x = -2x + 8 + 2x
3x - 7 = 8
Add 7 to both sides
3x - 7 + 7 = 8 + 7
3x = 15
3x = 15
x = 5
y = 5 - 7
y = -2
Solution (5, -2)
