Answer:

6

Step-by-step explanation:

Answer:

b.) 2

Explanation:

Parallel slopes have same slope.

Perpendicular slopes have negatively inverse slope.

[tex]\sf Here \ given \ equation: y = -\dfrac{1}{2} x - 6[/tex]

Comparing it with slope intercept form, "y = mx + b" where m is slope.

Here parallel slope: -1/2

Perpendicular slope: -(-1/2)⁻¹ = 2

Answer:

A.) The function is increasing for all real values of x where x < -4

Step-by-step explanation:

On the interval x < -4, all of the x values are increasing. Before x = -4, the line assumes a positive slope because it is heading upwards. After this interval, the function is decreasing because the slope is heading downwards.

On the interval -6 < x < -2, all of the x values are positive because they lie above the x-axis. This does not necessarily mean that all of the values are increasing.

On the interval x < -6 and x > -2, all of the x values are negative because they lie below the x-axis.

The congruency statement is true TS ≅ HG. so option C is correct.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

Given information;

Triangle G H J is rotated 90 degrees about point X to form triangle S T R.

Triangle GHJ is rotated 90° about point X, resulting in triangle STR.

Now, if any triangle is rotated 90 degrees about a point the two sides will be ≅ to each other.

So, ST = GH

RT= HJ

SR= GJ

<S= <G

<T = <H

<R=<J

The side TS ≅ HG.

Step-by-step explanation:

To write the probability as a fraction, put the total number on the bottom and put the number of ways the event can happen, put that on top.

They said there are 38 slots. That's the total, it goes on the bottom.

Landing on an Odd Number is the event we're looking at. There are 18 ways that can happen: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35

Question : Prism A and Prism B have the same volume. Which could be the dimensions of prism B?

Prism A :

Length = 8 feet

Width = 4 feet

Height = 5 feet

Prism B:

Length = ? feet

Width = ? feet

Height = ? feet

Option 1:

Length = 6 feet

Width = 10 feet

Height = 2 feet

Option 2:

Length = 4 feet

Width = 4 feet

Height = 10 feet

Option 3:

Length = 5 feet

Width = 4 feet

Height = 7 feet

Option 4:

Length = 8 feet

Width = 4 feet

Height = 6 feet

Here, the dimensions of the prism B will be length = 4 feet, width = 4 feet, and height = 10 feet.

We know that if the a and b be the length and width of the base respectively and c be the height of a prism, then the volume of the prism is abc.

Given that

length of 1st prism = 8 feet

width of 1st prism = 4 feet

height of 1st prism = 5 feet

So volume of 1st prism = 8 * 4 * 5 = 160 feet³

Now the volume of 1st and 2nd prisms are the same.

So, we have to check the options for length, width, and height of the 2nd prism.

1st option:

Height = 6 feet

Width = 10 feet

Length = 2 feet

So, volume = 6 * 10 * 2 = 120 feet³

Then the 1st option is incorrect.

2nd option:

Height = 4 feet

Width = 4 feet

Length = 10 feet

So, volume = 4 * 4 * 10 = 160 feet³

Then the 2nd option is correct.

Therefore, the dimensions of the prism B will be length = 4 feet, width = 4 feet, and height = 10 feet. The 2nd option is correct.

The inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

In the question, we are given that George bought socks for $300.

Therefore, George's total cost = $300.

We assume the number of pairs of socks George sells to be s.

The unit price per pair quoted by George = $6

Therefore, George's total sales = $6s.

We know that the profit over a transaction is given as the difference between sales and costs, that is,

The profit = The total sales - the total costs,

or, profit = 6s - 300.

In the question, we are required to make a profit of more than 210.

This can be shown by the inequality,

6s - 300 > 210.

Thus, the inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

Answer:

There are two sets of numbers that meet the criteria:

1)  8 and 16, or

2) -8 and -16

Step-by-step explanation:

Let's call the two numbers A and B.

We are told:

1) A-B=8, and

2) A^2 + B^2 = 320

Rearrange 1) to solve for A:

A=8+B

Use this value of A in the second equation:

A^2 + B^2 = 320

(8+B)^2 + B^2 = 320

(64+ 16B + B^2) + B^2 = 320

2B^2 + 16B + 64 = 320

B^2 + 8B + 32 = 160

B^2 + 8B + 32 = 160

B^2 + 8B - 128 = 0

(B+16)(B-8)=0

B is either -16 or +8

Assuming B = 8

Then from A-B=8 we find that A = B+8 and A = 16

Does A^2 + B^2 = 320?

  (16)^2 + (8)^2 = 320?

  256 + 64 = 320?  YES

--------------------------------

Assuming B=-16

If B=-16, then from A-B=8 we find that A = 8+(-16) and A = -8

Does A-B=8?

 -8 - (-16) = 8?  YES

Does A^2 + B^2 = 320?

 (-8)^2 + (-16)^2 = 320?

 64  + 256 = 320?  YES

5x²+20x+16y-15=0 is the equation, in vertex form, for the given parabolas.

We need to determine the equation, in vertex form, for the following parabolas.

We can find the parabola's equation in vertex form following two steps:

Step 1: Use the (known) coordinates of the vertex, (h,k), to write the parabola's equation in the form: y=a(x−h)²+k.

Step 2: Find the value of the coefficient a by substituting the coordinates of the point into the equation written in step 1 and solving for a.

Now, substitute (−2, 5) in y=a(x−h)²+k

⇒y=a(x−(-2))²+5

Now, substitute (2, 0) in y=a(x−(-2))²+5.

0=a(2+2)²+5

⇒a=-5/16

So, y=-5/16(x+2)²+5

⇒16y=-5(x²+4x+4)+5

⇒16y=-5x²-20x-20+5

⇒5x²+20x+16y-15=0.

Therefore, 5x²+20x+16y-15=0 is the equation, in vertex form, for the given parabolas.
