Answer:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form"

Answer:
Step-by-step explanation:
Let 25% solution is x liters, then 50% solution is (80 - x) liters.
<u>Acid content is going to be same:</u>
- 0.25x + 0.5(80 - x) = 80*0.4
- 0.25x - 0.5x + 40 = 32
- 0.25x = 8
- x = 8/0.25
- x = 32 liters
So 32 liters of 25% solution and 80 - 32 = 48 liters of 50% solution
The answer is B. Adjacent angles. They both have a meeting point and don't overlap.
The answer isn't A. because both angles don't add up to 90°.
The answer isn't C. because both angles aren't 90°.
The answer isn't D. because both angles don't add up to 180°.
Hope this helps! :)
