I'll be solving this by using the Triangle Inequality Theorem: a+b>c, a+c>b, and b+c>a

A. 54 mm, 65 mm, and 120 mm: 54=a, 65=b, 120=c and 54 + 65 > 120 so it's false.

B. 12 in, 43 in, and 56 in: 12=a, 43=b, 56=c, 12 + 43 > 56 so false

C. 16 ft, 24 ft, and 42 ft: 24=a, 16=b, 42=c, but 16 + 24 > 60 so it's false

D. 21 cm, 41 cm, and 60 cm: 21=a, 41=b, 60=c

21 + 41 > 60

21 + 60 > 41

41 + 60 > 21

It equals all three formulas so D is the right answer.

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Find the vertex and zeros of the following function f(x)=x^2-6x-7

elena-s [515]

Try this solution:

Step-by-step explanation:

1) for zeros of the function: x²-6x-7=0; ⇒ x₁=7; x₂= -1.

2) for the vertex of the function: x₀= -b/2a, where a;b;c - numbers from ax²+bx+c=0 (from x²-6x-7=0).

x₀=6/2=3;

y₀= (4ac-b²)/4a; ⇒ y₀= -16.

It means, the coordinates of the vertex are (3;-16).

Based on the information below, what are the values of x and y of the solution to the system of equations used to create the inf

Alborosie

Answer:

Option D) is correct

That is x=2 , y=-5

Step-by-step explanation:

Given that the $|A|=\left| \begin{array}{cc}4&-6\\ 8&-2\end{array}\right|, \left|A_x\right|=\left|\begin{array}{cc}38&-6\\ 28&-2\end{array}\right|, \left|A_y\right|=\left|\begin{array}{cc}4&38\\ 8&26\end{array}\right|$

To find their determinants

$|A|=\left| \begin{array}{cc}4&-6\\ 8&-2\end{array}\right|$

=-8+48

=40

Therefore $|A|=40$

$|A_x|=\left|\begin{array}{cc}38&-6\\ 28&-2\end{array}\right|$

=-76+156

=80

Therefore $|A_x|=80$

$|A_y|=\left|\begin{array}{cc}4&38\\ 8&26\end{array}\right|$

=104-304

=-200

Therefore $|A_y|=-200$

To find the values of x and y:

$x=\frac{|A_x|}{|A|}\ \textrm{and}\ y=\frac{|A_y|}{|A|}$

$x=\frac{80}{40}$ and $y=\frac{-200}{40}$

x=2 and y=-5

Option D) is correct

That is x=2 , y=-5
