To find the result when 20 is increased by 95%, you will need to calculate 95% of 20, which is 19, and then add it to 20. The result is 39.
To find the result when 20 is increased by 95%, you will need to calculate 95% of 20 and add it to 20. Here's how:
So, the result when 20 is increased by 95% is 39.

Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.
