Answer:

see below

Step-by-step explanation:

-2x + 9 < x − 9

Add 2x to each side

2x-2x + 9 < 2x+x − 9

9 < 3x-9

Add 9 to each side

9+9 < 3x

18 < 3x

Divide each side  by 3

18/3 < 3x/3

6 < x

Open circle  at 6 line going to the right

Answer:6 to the right of the number line

Answer:

(3 x + 4) (x - 1) (x + 3)

Step-by-step explanation:

Factor the following:

3 x^3 + 10 x^2 - x - 12

The possible rational roots of 3 x^3 + 10 x^2 - x - 12 are x = ± 1/3, x = ± 2/3, x = ± 4/3, x = ± 1, x = ± 2, x = ± 3, x = ± 4, x = ± 6, x = ± 12. Of these, x = -4/3, x = 1 and x = -3 are roots. This gives 3 x + 4, x - 1 and x + 3 as all factors:

Answer: (3 x + 4) (x - 1) (x + 3)

Answer:

(D)$81

Step-by-step explanation:

Given that the number of purses a vendor sells daily has the probability distribution represented in the table.

Expected Value, [tex]E(x)=\sum_{i=1}^{n}x\cdot p(x)[/tex]

Therefore:

[tex]E(x)=(0X0.35)+(1X0.15)+(2X0.2)+(3X0.2)+(4X0.03)+(5X0.07)\\=0+0.15+0.4+0.6+0.12+0.35\\E(x)=1.62[/tex]

If each purse sells for $50.00, the number of expected daily total dollar amount taken in by the vendor from the sale of purses

=Expected Value X $50

=1.62 X $50

=$81

The correct option is D.

Step-by-step explanation:

Step 1:  Answer the question

This algebraic expression is not a polynomial therefore, none of these options match except D.  The reason why it is not a polynomial is because there is a 7^x which is not a polynomial expression.  The expression needs to be expressed as a 7x^2 + 2x + 1.  Therefore, the answer is D.

Answer:  D, none

I WILL SAY THE 2 ONE

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

The solution of number is, 200.

We have to given that;

To find a number which is 30% of  number is 60.

Let us assume that,

A number is, x

Hence, We can formulate;

⇒ 60 = 30% of x

⇒ 60 = 30/100 × x

⇒ 60 = 3x / 10

⇒ 600 = 3x

⇒ 3x = 600

⇒ x = 200

Thus, The solution of number is, 600

Answer:

83

Step-by-step explanation:

You are trying to find the score that gives you a specific mean.  A mean is calculated by dividing the sum of the data by the amount of data.  Set up in this order, with x as the fourth score, to find the answer.

[tex]\frac{71+80+86+x}{4}=80\\\frac{237+x}{4} =80\\237+x=320\\x=83[/tex]

The fourth test score must be an 83.

Answer:

83

Step-by-step explanation:

Equation: 71 + 80 + 86 + x / 4 = 80

Add 71, 80, and 86 together.

237 + x = 80

Multiply 4 to both sides (cross multiplying).

237 + x = 320

Subtract 237 from both sides.

x = 83

Answer:

Step-by-step explanation:

Considering a person peak blood is 0.07

It decrease by 4% every hour

a) Using exponential function

[tex]f(x) = Ca^x[/tex]

where,

a = 1 + r

r = -0.40%

Here,

C = 0.07,

a = 1 - 0.04 = 0.06

[tex]f(x)=0.07(0.6)^x[/tex]

b)

Here the hourly decay factor is 0.6

[tex]B(x)=ca^x\\\\0.07(0.6)^x[/tex]

c) Evaluate

[tex]B(2)=0.07\times (0.6)^2\\\\0.07(0.36)\\\\= 0.0252g[/tex]

0.0252g or 100mL

Answer:

a) Hourly decay factor = 0.6

b) [tex]B(x) = 0.07(0.6)^x[/tex]

c) B(2) = 0.0252

This result means that the blood alcohol level will be 0.0252 (grams per 100 ml) after 2 hours

Step-by-step explanation:

Since the function is an exponential function, it can be modeled as:

[tex]B(x) = C (1 + r)^x[/tex]

Where the peak blood alcohol level, C = 0.07

Since the blood level decreases by 40%(0.4) every hour, r = -0.4

The hourly decay factor is given by a = 1 + r

a = 1 + (-0.4) = 1 - 0.4

a = 0.6

Therefore, the hourly decay factor = 0.6

b) The exponential function is:

[tex]B(x) = Ca^x[/tex]

Where a = 1 + r = 0.6

C = 0.07

[tex]B(x) = 0.07(0.6)^x[/tex]

c) Evaluate B(2)

Substitute x = 2 into the exponential function gotten in part (b)

[tex]B(2) = 0.07(0.6)^2\\B(2) = 0.0252[/tex]

This result means that the blood alcohol level will be 0.0252 (grams per 100 ml) after 2 hours

D. Division and Addition

Step-by-step explanation:

Answer:

Step-by-step explanation:

The main equivalence between rectangular and polar forms is

x^2 + y^2 = r^2, where r is the radius.  Next, y = r sin Ф.  Thus,

x^2 + y^2 = r^2 becomes r² = 2·r·sin Ф.

The variable r can be factored out partially:  r = 2·sin Ф

This is the polar form of x^2 + y^2 = 2y.

Answer: y =x2 (squared)−3x−10

Step-by-step explanation:

Answer:

What are the roots of y [tex]y=x^{2}-3x-10[/tex]?

Step-by-step explanation:

The given equation in two variables is [tex]y=x^{2}-3x 10 y = x 2 - 3 x - 10[/tex] .

We are asked to find the roots. We will now apply the zero factor property

by equating each factor to zero. Thus, the roots of the equation are

Answer:  (-6,7)

Step-by-step explanation:

Tow points, (x1, y1) and (x2, y2) are simetric in a quadratic graph when:

f(x1) = y1 = f(x2) = y2

so y1 = y2

Then if we have the point (2,7) we want to find other point that has the same value for y, this is (-6, 7)

So the correct option is  (-6,7)

Answer: 3

Step-by-step explanation: if you had the histogram..... the first is 14 and the second is 14 too, but the first one you divide by 4 because there are only 4 lines, so that gives you 3.5

The second one you divide by 5

So, 14 divided by 5 is

2.8

If you round both of these you should have around 3

Therefore, the answer is 3

Answer:

Correct option: d -> 40,320

Step-by-step explanation:

To find all the arrangements of letters in a word where all the letters are different, we just need to calculate the factorial of the number of letters.

The word "grateful" has 8 different letters, so the number of arrangements of letters is:

8! = 8*7*6*5*4*3*2 = 40,320 different arrangements
