Hello from MrBillDoesMath!

Answer:    A, C, D

Discussion:

The solution of the quadratic equation  ax^2 + bx + c = 0  is


x =        ( -b  +\-   (b^2 - 4ac) ^ (1/2) ) /2a


The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution,  and also occurs inside a square root (called a radicand).

The question, while intelligible, should be stated more clearly.  

Regards, MrB

Write -3/4x-6 in standard form using integers
taurus [48]

Answer:

3x+4y=-24

Therefore, option C is correct.

Step-by-step explanation:

We have been given the equation:

y=\frac{-3x}{4}-6[/

We will take LCM 4 on right hand side of the above equation:

y=\frac{-3x-24}{4}

Now, we will multiply the 4 in denominator on right hand side to the y in left hand side pof the equation we get:

4y=-3x-24

After rearranging the terms we get:

3x+4y=-24

Therefore, option C is correct.

Through: (4, -3), perp. to y=-2x + 1
larisa86 [58]

Step-by-step explanation:

y = -2x + 1. => Slope = -2

Then the perpendicular line will have a slope of -1/(-2) = 0.5.

We have y = 0.5x + c.

When x = 4, y = -3.

=> (-3) = 0.5(4) + c, c = -5.

Hence the answer is y = 0.5x - 5. (C)

Which graph represents the piecewise-defined function? y={−45x−3   if  x&lt;03x−10   if  x≥2
Nikitich [7]

Step-by-step explanation:

y=\left \Bigg\{ {\big{-45x-3 \qquad x < 0} \atop \big{3x - 10 \qquad x \geq2 }} \right.

\begin {array}{c|c}{ x&y}}\\ -\infty&-\infty\\-2&-93\\-1&-48\\ 0 &-3^*\\1&nothing\\2&-4\\3&-1\\4&2\\ \infty&\infty\\\end{array}

* open dot

You did not provide the graphs to choose from so use the table above to determine which graph fits those coordinates.

Make sure that:

  • (0, -3) has an open dot
  • nothing is plotted between x = 0 and x = 2
  • (2, -4) has a closed dot
