Answer:

\boxed {r = -\frac{1}{5}}

Step-by-step explanation:

Solve for the value of r:

5(r - 10) = -51

-Use <u>Distributive Property</u>:

5(r - 10) = -51

5r - 50 = -51

-Add 50 on both sides:

5r - 50 + 50 = -51 +50

5r = -1

-Take 5 and divide it on both sides:

\frac{5r}{5} = \frac{-1}{5}

\boxed {r = -\frac{1}{5}}

Therefore, the value of r is -\frac{1}{5}.

Sam is determining the area of a triangle. In this triangle, the value for the height is a terminating decimal, and the value fo
snow_tiger [21]

Answer:

The area is rational because the numbers in the formula are rational.

Step-by-step explanation:

All repeating decimals are still rational because they can be expressed as fractions. For example,

$\frac{1}{7}=0.\overline{142857}$\end{document}

So every recurring decimal must be a fraction.

Also every terminating decimal can be represented as a fraction.

0.25  =  \frac{1}{4}

So  the area is rational because the numbers are rational.

Area = \frac{1}{2} X Base X Height

Base is Rational and Height is Rational. Hence Area=Rational.

When these rational numbers are substituted into the formula,the area must be rational.

What is the vertex of the graph of this equation y= -4x^2-16x-12
Lisa [10]
One way to locate the vertex is to obtain the coefficients a, b and c from the quadratic and then calculate  
                                      -(-16)
x = -b / (2a).  Here, x = ---------- = -2
                                       2(-4)

Next, evaluate y at x = -2:  y = -4(-2)^2 - 16(-2) - 12 = -16 + 32  - 12
                                           y = 4

the vertex is at (-2,4).
