Please help (4x - 1)(2x + 3)

Answer:

a)64

b)512

c)2^12

d)2^3m

Step-by-step explanation:

At every meal, 3 ounces of the cake is eaten

a) After 2 meals, the number of ounces consumed is 6 ounces

For each ounce, height is doubled , for 6 ounces, we have 2 * 2 * 2 * 2 * 2 * 2

Her height is multiplied by 64

b) After three meals

Total consumption is 3 * 3 = 9 ounces

So her height will be multiplied by 2^9 = 512

c) After four meals

Total ounces is 4 * 3 = 12

So her height will be multiplied by 2^12

d) After M meals

Number of ounces is m * 3 = 3m ounces

Her height will be multiplied by 2^3m

Answer:

Yes

Step-by-step explanation:

There is only one y value for each x value. That is the definition of a function.

Hope I helped!!!

Answer:

i believe all you have to do is divide the (x) nums into the (y) nums and if there whole nums it is a function

Step-by-step explanation:

Answer:

Absolute value means the non-negative, or the positive, of it's number, since eight is already a positive number, it's absolute value remains positive eight.

But since -8 is a negative number, the absolue value will give eight it's non-negative, which is positive eight.

Answer:

44% of 50 is 22.

This is the case because 50 * 0.44 is 22.

Let me know if you have any other questions :)

Answer:

50

Step-by-step explanation:

44% = 44/100

44/100 × X = 22

X = 22 × 100/44

X = 100/2

X= 50

hence, 44% of 50 is 22

Answer:

The interest Jacob earns after 6 years is $8.82

Step-by-step explanation:

The given parameters are;

The simple interest rate of the savings account, R = 1%

The principal deposit to the savings account, P = $147

The time duration Jacob saved the money, T = 6 years

The formula for simple interest, I, is given as follows;

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

Substituting the known values gives;

[tex]I = \dfrac{147 \times 1 \times 6}{100} = 8.82[/tex]

The interest Jacob earns after 6 years = $8.82.

Answer:

The annual total cost is $135 when he purchases 17 books

Step-by-step explanation:

Given function is:

C(b) = 5b + 50

Here c is the output which is cost and b is the input which is number of books purchased in an year.

In order to find the total cost when he purchases 17 books, we have to put 17 in place of b and find the cost.

So,

Putting b = 17

[tex]C(17) = 5(17) + 50\\= 85+50 = 135[/tex]

Hence,

The annual total cost is $135 when he purchases 17 books

Answer:

343,200 ft/3600

Step-by-step explanation:

multiply 5280 by 65. To find the seconds multiply 60 by 60 to get 3600

Answer:

Hey! so if you want to know the distance of how many feet it went in 65 miles an hour you have to multiply so. 5,280 ft x 65 mi/hr. = 343,200 ft

Answer:

1086

Step-by-step explanation:

BODMASS (Multiplication first, addition after)...

15×72= 1080

1080+6= 1086

hope it helps

Because of PEMDAS, Simplify 15x72 first. That will bring you to 1080. After that we add 6 to the 1080 because you always do Multiplication first. Your answer would be 1086 if you followed PEMDAS correctly.

PEMDAS:

1. Parentheses

2. Exponents

3. Multiplication

4. Division

5. Addition

6. Subtraction

That's the order of operations if you ever want to know what to do first.

Answer:

10 feet

Step-by-step explanation:

The formula for the Perimeter fo a rectangle

= P = 2L + 2W

Where:

L = Length

W = Width

From the question

P = 80 feet

W = 30 feet

Hence:

80 = 2L + 2(30)

80 - 2(30) = 2L

80 - 60 = 2L

20 = 2L

L = 20/2

L = 10 feet

Hence, the length of the fenced area = 10 feet

Answer:

100 percent

Step-by-step explanation:

The number did not change

Answer:

The answer is C, or the third one (8/26).

Step-by-step explanation:

You add up all the objects (5+6+8+7) and get a total of 26 objects. Now you go to the amount of blue ones, and it's 8. So your probability of getting a blue one is 8 out of 26, since there's 8 blue ones out of the total 26. You can write this as 8/26, which is the answer.

Answer:

x=0

Step-by-step explanation:

simplify: 15(x-3) over 15 ( srry i dont know how to make that a fraction.)

3(2x-3)= 3x-9

3x-9=6x-9

move all terms containing x to the left side of the equation

-3x-9=-9

move all terms not containing x to the right side of the equation

-3x=0

divide both sides by -3 and simplify if needed

x=0

Answer:

$175.80

Step-by-step explanation:

Answer:

175.80$

Step-by-step explanation:

In order to find the answer to this question you must first find 20% of the cost for the dinner, then add that answer to the cost of the dinner to receive your answer.

[tex]146.50[/tex]

[tex]20 =146.50[/tex]

[tex]Y=P\times X[/tex]

[tex]20\times146.50[/tex]

[tex]20\div100=0.2[/tex]

[tex]0.2\times146.50[/tex]

[tex]0.2\times146.50=29.3[/tex]

[tex]=29.3[/tex]

Now add:

[tex]146.50+29.3=175.80[/tex]

[tex]=175.80[/tex]

Hope this helps.

Answer:

Option (C)

Step-by-step explanation:

Geometric sequence has been given as,

6, -24, 96. -384.......

First term of this sequence = 6

[tex]a_1=6[/tex]

Recursive formula of geometric sequence is given by,

[tex]a_n=a_{n-1}(r)[/tex]

Here r = common ratio of successive and previous term

From the given sequence,

r = [tex]\frac{a_2}{a_1}[/tex]

 = [tex]\frac{-24}{6}[/tex]

 = (-4)

Recursive formula of the given sequence will be,

[tex]a_n=a_{n-1}.(-4)[/tex]

Therefore, Option (C) will be the correct option.

Answer:

Solve the first equation for y

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the matrix is not given.

The general form of a matrix is:

[tex]b[m*n] =\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}........b{1n}}\\b_{21}&b_{22}&b_{23}........b{2n}\\b_{31}&b_{32}&b_{33}........b{3n}\\ \\ \\b_{m1}&b_{m2}&b_{m3}........b{mn}\end{array}\right][/tex]

Where m and n represent the [tex]number\ of\ rows\ and\ columns[/tex] respectively.

Notice the position of b11

This means that b11 is at the first column and first row.

Take for instance matrix b is:

[tex]b = \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]

The element at the first row and first column is 1.

Hence

[tex]b_{11} = 1[/tex]

Answer:

Step-by-step explanation:

Answer:

y=1/2x+35

Step-by-step explanation:

Find two points: 0,35 and 40,65.

65-35 is 20/40 or 1/2

y=1/2x+b

plug in 0,35

35=b

y=1/2x+35.
