Answer:

4 >x

Step-by-step explanation:

3(x + 6) – 2(x – 4) > 5(x + 2)

Distribute

3x+18 -2x+8 > 5x+10

Combine like terms

x +26 > 5x+10

Subtract x from each side

x+26-x > 5x-x+10

26 > 4x+10

Subtract 10 from each side

26-10 >4x+10-10

16 >4x

Divide each side by 4

16/4 >4x/4

4 >x

Answer:

The initial value of the boat was $20,000

The percent decrease per year of the value of the boat is 10%.

The interval on which the value of the boat is decreasing while Harry has it is (0,10)

Step-by-step explanation:

It is given that the boat costs $20,000 in 2010 when x = 0. So, the initial value of the boat was $20,000.

Next, find the percent decrease per year of the value of the boat. Consider the general form of an exponential equation, y = a(b)x, where a is the initial value of the boat, b is the base of the exponent, x is the number of years after 2010, and y is the value of the boat, in dollars.

Consider the point (1 , 18,000) which lies on the graph of this situation. Substitute x = 1, y = 18,000, and a = 20,000 into the exponential equation and isolate b.

Recall that for exponential decay, b = 1 - r where r represents the decay rate. Substitute b = 0.9 into this equation and solve for r.

So, the decay rate is 0.1, and the percent decrease per year of the value of the boat is 10%.

Harry bought the boat in 2010, and plans on selling it after 10 years in 2020. Therefore, the interval on which the value of the boat is decreasing while Harry has it is [0, 10].

Ok so the mean is the average of all the data. So we add up all the numbers, then divide that by the quantity of numbers.

For week one, thats 48,52,52,53,60,63,65 which equals 393, then we divide that by 7, and get 56.142857142857, so we round that to 56.1

Week 2 is 54,55,56,59,60,62,63 which is 409 divided by 7, and thats 58.428571428571 rounded is 58.4

Next up is the MAD (mean absolute deviation) thats the average distance between each value and the mean.

Week 1 MAD: 5.5918367346939 5.5

Week 2 MAD: 2.9387755102041 2.9

Answer: the sum of their measures is 180 degrees

Step-by-step explanation:

I just got it right

The angles R T S and Q T P are vertically opposite angles. So that they always have equal measures.

In given circle, T is center of circle .

and RP and SQ are diameter of circle which are intersecting at center T.

The diagram of circle is attached below.

In the diagram of circle, Angles R T S and Q T P are congruent.

So that,  [tex]\angle RTS=\angle QTP\\\\[/tex]

Since, both diameter are crossing each other.

Step-by-step explanation:

If you use the Triangle Inequality Theorem, you will find that 4+10 equals 14, which is less than 16. It has to be greater than 16 to be a triangle.

Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.

Given that, a triangle with sides measuring 4 ft, 10 ft, and 16 ft.

In the triangle, the sum of any two sides is always greater than the third side. The difference between any two sides of the triangle is always less than the third side.

Answer:

32 chairs

Step-by-step explanation:

In the soft Boulder cafe they a chairs , table and customers and the 3 members staffs.

Each Table = 3 legs

Each Chairs = 4 legs

Each customer  = 2 legs

Each members of staffs = 2 legs

4 chairs goes with each table. This means 4 × 4 = 16 legs of chairs for each 3 legs of table.

At a certain time 3/4 of the chairs are occupied by customers. That is 3 out of 4 chairs are occupied plus 6 tables . Therefore,

3 + 16 + 6 = 25 legs of table

206 legs altogether - the 6 legs of the staff(3 staffs has 6 legs)= 200 legs

This means 200 legs = 8 tables. Therefore,

8 tables requires 32 chairs

So, let's start off with h

The expression needs to be '3 more than h'

This can be written as:

h + 3

The expression also needs to be 'five times' this value

This can be written as:

5(h + 3)

That would be your answer ^^

Answer:

Peter is 20 years old

Step-by-step explanation:

John= 2(Peter's age) (j=2p)

Peter= (Alice's age + 5) (P= A+5)

Okay, so let's substitute the equations now:

John= 2(Alice + 5)

So the equation for 5 years from now is:

2(A+5) + 5 = 3a (because he is 3 times as old as alice)

so, let's solve for that equation:

2a + 10 + 5 = 3a

subtract 2a from both sides:

15= a

so, Alice is going to be 15 years old, so now we can solve for Peter's age:

P= A + 5

P= 15 + 5

P = 20

Peter is 20 years old

Answer:

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find b

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

Answer:

[tex]f(x) = -2(x - 4)^2 -3[/tex]

Vertex = (4, -3)

Graph in the image attached, additional points:

(2, -11), (3, -5), (5, -5), (6, -11)

Step-by-step explanation:

The vertex of f(x) can be found using the formula:

[tex]x_{vertex} = -b/2a[/tex]

[tex]x_{vertex} = -16 / (-4)[/tex]

[tex]x_{vertex} = 4[/tex]

to find y_vertex, we use x_vertex in f(x):

[tex]f(x_{vertex}) = -2 * 4^2 + 16*4 - 35[/tex]

[tex]f(x_{vertex}) = -3[/tex]

So the vertex is (4, -3)

To write the function in the form [tex]f(x)=a(x-h)^2+k[/tex], we just need to calculate h = -b/2a and then find k:

[tex]h = -b/2a = -16/(-4) = 4[/tex]

[tex]f(x) = -2(x - 4)^2 + k = -2(x^2 - 8x + 16) + k = -2x^2 + 16x - 32 + k[/tex]

Comparing both forms of f(x), we have:

[tex]-32 + k = -35[/tex]

[tex]k = -3[/tex]

So we have:

[tex]f(x) = -2(x - 4)^2 -3[/tex]

Now let's find the four additional points.

Two points to the left: x = 3 and x = 2

[tex]f(3) = -2 * 3^2 + 16*3 - 35 = -5[/tex]

[tex]f(2) = -2 * 2^2 + 16*2 - 35 = -11[/tex]

Two points to the right: x = 5 and x = 6

[tex]f(5) = -2 * 5^2 + 16*5 - 35 = -5[/tex]

[tex]f(6) = -2 * 6^2 + 16*6 - 35 = -11[/tex]
