Here are some helpful rules that will help you out in the future with these questions.

If...

a^2 + b^2 = c^2 its a right triangle

a^2 + b^2 < c^2 its obtuse

a^2 + b^2 > c^2 its acute

so...

Since 6+8>10

The row-echelon form of the augmented matrix of a system of equations is given. Find the solution of the system.
Zepler [3.9K]

Answer:

option-C

Step-by-step explanation:

We are given row-echelon form

So, we can write equation from matrix as

x-5z=-3

y-4z=-5

Let's assume

z=t

now, we can find x and y

x-5t=-3

x=5t-3

y-4t=-5

y=4t-5

so, we get solutions as

x=5t-3

y=4t-5

z=t

where t can be any real numbers

This question has two parts. Be sure to answer both parts of the question. One inequality in a system is shown below. -12x + 3y
fgiga [73]

The inequality is -12x + 3y > 9.

PART A:

The sytem has no solution if inequality does not share a common area. The inequality -12x + 3y > 9 consist the region to left of line -12x + 3y = 9. So for no solution the region to left of equation -12x + 3y = 9 is suitable.

Thus inequality for no solution is, -12x + 3y < 9.

PART B:

For infinite solution the region of both inequality must overlap each other, or the inequality is same with some multiplication of divison factor. So inequality for infinite many solutions is,

\begin{gathered} (-12x+3y>9)\times-1 \\ 12x-3y

Thus inequality for infinite many solution is 12x - 3y < -9.

6. Protein bars come in a 4-pack box or 12-pack
cricket20 [7]

Answer:

The 12 pack has a better value.

Step-by-step explanation:

1. create a ratio table.

you want to know how much the 4 pack would cost if it was a 12 pack.

you can see the ratio table in the picture above.

As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.

<em>Then</em><em>,</em><em> </em><em>compare</em><em> </em><em>2</em><em>3</em><em>.</em><em>0</em><em>4</em><em> </em><em>to</em><em> </em><em>2</em><em>2</em><em>.</em><em>3</em><em>2</em><em>.</em><em> </em>

<u>In</u><u> </u><u>conclusion</u><u>,</u><u> </u><u>the</u><u> </u><u>1</u><u>2</u><u> </u><u>pack</u><u> </u><u>has</u><u> </u><u>a</u><u> </u><u>better</u><u> </u><u>value</u><u>.</u>

A copying machine reduces a 12 cm line to 10.5 cm
Dmitrij [34]

Answer:

14cm

Step-by-step explanation:

10.5 is 87.5% of 12, and 87.5% x 16 = 14

you can find the percentage by using 10.5/12 and x/100 to find x

10.5 * 100 = 1050

1050/12=87.5
