I am very confused please solve and explain.
e-lub [12.9K]

Answer:

c = \frac{b^2-R^2}{4a}

Step-by-step explanation:

Given

R= \sqrt{b^2-4ac}

Clear the radical by squaring both sides

R² = b² - 4ac ( subtract b² from both sides )

R² - b² = - 4ac ( multiply all terms by - 1 )

b² - R² = 4ac ( divide both sides by 4a )

\frac{b^2-R^2}{4a} = c

31.) State the slope of the line shown below.
Murljashka [212]
The answer is undefined


The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

If a student didn’t understand proportional relationships, how would you explain it to them?
kirill [66]

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!
