Answer: A) Point B, because if cups of frosting are 50, then drops of food coloring will be 200.


This is because the proportion of frosting to food coloring is 1:4, and if the answer to A is simplified (50:200), the ratio would be the same.

Answer:

Option A. will be the answer.

Step-by-step explanation:

From the given table we will find the relation first and the we will try to find the point with the same relation in the graph.

From the given table ratio of Cups of frosting and Drops of food color is = \frac{\text{Cups of frosting}}{\text{Drops of food color}}

= \frac{2}{8}

= \frac{1}{4}

Or 1 : 4

Now the point B shows the ratio between food color and frosting = \frac{\text{Cups of frosting}}{\text{Drops of food color}}

= \frac{\text{x-coordinates}}{\text{y-coordinates}}

= \frac{50}{200}

= \frac{1}{4}

The same ratio 1 : 4

Option A. will be the answer.

Does anyone know the answer to this one?
polet [3.4K]

Answer:

\large\boxed{a(x+4)(x-5)=0,\ a\in\mathbb{R}-\{0\}}\\\\\text{for}\ a=1\to\boxed{x^2-x-20=0}

Step-by-step explanation:

\text{If}\ x_1\ \text{and}\ x_2\ \text{are the roots of the quadratic equation}\ ax^2+bx+c=0,\\\text{then}\ ax^2+bx+c=a(x-x_1)(x-x_2).\\\\\text{If}\ x_1\ \text{and}\ x_2\ \text{, then they are the roots of the quadratic equation.}\\\\\text{We have}\ x_1=-4\ \text{and}\ x_2=5.\ \text{Therefore we have the equation:}\\\\a(x-(-4))(x-5)=0\\\\a(x+4)(x-5)=0\qquad\text{for any value of}\ a\ \text{except 0}.

5-2(2x - 3) = 12<br><br> Cual es el resultado de x?
postnew [5]

Answer:

<h2>x =  -  \frac{1}{4}</h2>

Step-by-step explanation:

5-2(2x - 3) = 12

<u>Expanda los términos en el corchete</u>

Eso es

5 - 4x + 6 = 12

<u>Agrupar términos similares</u>

Envíe las constantes al lado derecho de la ecuación y aquellas con variables al lado izquierdo

Tenemos

- 4x = 12 - 5 - 6

- 4x = 1

Divide ambos lados entre - 4

<h3>-  \frac{4x}{ - 4}  =   - \frac{1 }{4}</h3>

Tenemos la respuesta final como

<h3>x =  -  \frac{1}{4}</h3>

Espero que esto te ayude

How would you draw a counterexample to this?
NeX [460]
Melanie said: 
Every angle bisector in a triangle bisects the opposite side perpendicularly.

A 'counterexample' would show an angle bisector in a triangle that DOESN'T
bisect the opposite side perpendicularly.

See my attached drawing of a counterexample.

Both of the triangles that Melanie examined have equal sides on both sides
of the angle bisector.  That's the only way that the angle bisector can bisect
the opposite side perpendicularly.  Melanie didn't examine enough different
triangles.
