Calculator 1: Calculate the percentage of a number.
For example: 87% of 55 = 47.85
Calculator 2: Calculate a percentage based on 2 numbers.
For example: 47.85/55 = 87%
To do this make x and y equal 0, y-intercept is at x=0, and x-intercept is at y=0:
x-intercept:
2x+7(0) = -14
2x = -14
x = -7
y-intercept:
2(0) + 7y = -14
7y = -14
y = -2
Answer:
<h2>x = -49</h2>
Step-by-step explanation:
x - 6 = -55 <em>add 6 to both sides</em>
x - 6 + 6 = -55 + 6
x = -49
