200 because 156 is closer to 200 than 100
The given equation is a Quadratic equation, so it's graph must be a parabola, and the Coefficient of x² is positive that means the parabola must have an opening upward.
And 2 is added to the ideal equation, so the parabola must have shift 2 units up from x - axis.
From the above information, we can easily conclude that the Correct representation is done in graph 4
The answer would be
~X > 3400~
Hope this helps
Have a great day/night

Answer:
83% remains in the box
Step-by-step explanation:
Here, we are interested in calculating the percentage of donuts remaining in the box.
From the question, we are told that 2 was eaten, the number of donuts left = 12-2 = 10 donuts
The percentage of donuts left would be;
Number of donuts left/Total no of donuts * 100%
= 10/12 * 100 = 83.33
Which is 83% to the nearest whole number percentage
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
