Step-by-step explanation:

g(x) = 3x² + 2

h(x) = 2x + 2

g(h(x)) = g([2x + 2]) = 3[2x+2]² + 2

= 3[4x² + 8x + 4] + 2

= 12x² + 24x + 12 + 2

= 12x²+ 24x + 14

Step-by-step explanation:

I'm going to assume 50.25 was a typo error and it is $0.25 for each extra minute.

For a 10 minute phone call, the first 5 minutes cost $3 and the other 5 minutes cost $0.25 * 5 = $1.25. Altogether it costs $4.25.

For a 15.5 minute phone call, the first 5 minutes cost $3 and the other 10.5 minutes cost $0.25 * 11 = $2.75. Altogether it costs $5.75.

Answer:

8. c. (-1, -1)

9. a. (-6, -1)

b. True

Step-by-step Explanation:

8. Given the midpoint M(2, 4), and one endpoint D(5, 7) of segment CD, the coordinate pair of the other endpoint C, can be calculated as follows:

let [tex] D(5, 7) = (x_2, y_2) [/tex]

[tex] C(?, ?) = (x_1, y_1) [/tex]

[tex] M(2, 4) = (\frac{x_1 + 5}{2}, \frac{y_1 + 7}{2}) [/tex]

Rewrite the equation to find the coordinates of C

[tex] 2 = \frac{x_1 + 5}{2} [/tex] and [tex] 4 = \frac{y_1 + 7}{2} [/tex]

Solve for each:

[tex] 2 = \frac{x_1 + 5}{2} [/tex]

[tex] 2*2 = \frac{x_1 + 5}{2}*2 [/tex]

[tex] 4 = x_1 + 5 [/tex]

[tex] 4 - 5 = x_1 + 5 - 5 [/tex]

[tex] -1 = x_1 [/tex]

[tex] x_1 = -1 [/tex]

[tex] 4 = \frac{y_1 + 7}{2} [/tex]

[tex] 4*2 = \frac{y_1 + 7}{2}*2 [/tex]

[tex] 8 = y_1 + 7 [/tex]

[tex] 8 - 7 = y_1 + 7 - 7 [/tex]

[tex] 1 = y_1 [/tex]

[tex] y_1 = 1 [/tex]

Coordinates of endpoint C is (-1, 1)

9. a.Given segment AB, with midpoint M(-4, -5), and endpoint A(-2, -9), find endpoint B as follows:

let [tex] A(-2, -9) = (x_2, y_2) [/tex]

[tex] B(?, ?) = (x_1, y_1) [/tex]

[tex] M(-4, -5) = (\frac{x_1 + (-2)}{2}, \frac{y_1 + (-9)}{2}) [/tex]

[tex] -4 = \frac{x_1 - 2}{2} [/tex] and [tex] -5 = \frac{y_1 - 9}{2} [/tex]

Solve for each:

[tex] -4 = \frac{x_1 - 2}{2} [/tex]

[tex] -4*2 = \frac{x_1 - 2}{2}*2 [/tex]

[tex] -8 = x_1 - 2 [/tex]

[tex] -8 + 2 = x_1 - 2 + 2 [/tex]

[tex] -6 = x_1 [/tex]

[tex] x_1 = -6 [/tex]

[tex] -5 = \frac{y_1 - 9}{2} [/tex]

[tex] -5*2 = \frac{y_1 - 9}{2}*2 [/tex]

[tex] -10 = y_1 - 9 [/tex]

[tex] -10 + 9 = y_1 - 9 + 9 [/tex]

[tex] -1 = y_1 [/tex]

[tex] y_1 = -1 [/tex]

Coordinates of endpoint B is (-6, -1)

b. The midpoint of a segment, is the middle of the segment. It divides the segment into two equal parts. The answer is TRUE.

I think this is correct you just count how , many letters she has in her name (that's gonna be our denominator) and then count how many of those are vowels (our numerator). to change it into a decimal you simply divide the top by the bottom.

Answer:

x = 9

Step-by-step explanation:

Simplifying

-4 = 5 + -1x

Solving

-4 = 5 + -1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.

-4 + x = 5 + -1x + x

Combine like terms: -1x + x = 0

-4 + x = 5 + 0

-4 + x = 5

Add '4' to each side of the equation.

-4 + 4 + x = 5 + 4

Combine like terms: -4 + 4 = 0

0 + x = 5 + 4

x = 5 + 4

Combine like terms: 5 + 4 = 9

x = 9

Simplifying

x = 9

Answer: The answer is x=9

Step-by-step explanation: Good afternoon, I got a different step-by-step explanation for you!!! :D Step 1: Simplify both sides of the equation: [tex]-4=5-x[/tex], [tex]-4=5+-x[/tex], and [tex]-4=-x+5[/tex]. Step 2. I flipped the equation: [tex]-x+5=-4[/tex].

Step 3. Subtract 5 from the both sides: [tex]-x+5-5=-4-5[/tex] to [tex]-x=-9[/tex].

Last but not least is step 4. Divide the both sides by –1: [tex]\frac{-x}{-1}=\frac{-9}{-1}[/tex]; ∴, your answer should be x=9, I hoped your answer is very helpful, please mark me as brainliest, and have a happy holidays!! :D

Answer:

250 i thoink

Step-by-step explanation:

For making 60 cookies the amount of butter will be 250 decigrams.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a recipe for shortbread cookies calls for 5 grams of butter to make 12 cookies.

The amount of butter for 60 cookies in decigrams will be calculated as,

12 cookies = 5 grams

12 cookies = 50 dg

60 cookies = ( 50 x 60 ) /60

60 cookies = 250 dg

Answer:

Mode: 42 Range: 9

Step-by-step explanation:

First, I used trial and error to find the value of x which I found out was 2. Next, I found out how many people were in each weight category. Then, I put the numbers in order from least to greatest which gave me 33,33,35,35,35,37,37,37,37,39,39,39,39,42,42,42,42,42. After that, I found the number that showed up the most in this set of data which is the mode. Finally, I subtracted the smallest number(33) from the greatest number(42) and got 9 which is the range.

Answer:

35 days

Step-by-step explanation:

A = 14 days

It means per day, work done by A= 1 / 14

A+B = 10 days

Work done by A and B per day = 1 / 10

In what time can B alone do the work?

To solve this, we have

A+B = A alone + B alone

1/10 = 1/14 + B alone

Subtract 1/14 from both sides

1/10 - 1/14 = 1/14 + B alone - 1/14

14-10/140 = B alone

4/140 = B alone

B alone= 1 / 35

Work done of B alone = 1/35

B alone will do the work in 35 days

Answer:

35 days.  

Step-by-step explanation:

A can do the work in 14 days: per day work done by A=1/14

A and B can do the work in 10 days: per day work done by A and B=1/10

Work is done by B per day=1/10–1/14=7/70-5/70=(7–5)/70=2/70=1/35.

So, B takes 35 days.

Answer:

The pile is 2 feet high.

Step-by-step explanation:

There are 6 blocks, each block is 4 inches in height. That means the total height is:

6×4=24 inches

Because the question asked for the answer in feet, you have to convert the 24 inches into feet:

24 inches=2 feet

Answer:

Step-by-step explanation:

4 1/2 divided by 4.

Given:

a. [tex]\sqrt{0.25},\sqrt{\dfrac{1}{9}},\dfrac{6}{25}[/tex]

b. [tex]\sqrt{\dfrac{121}{25}},2.25,\sqrt{5}[/tex]

To find:

The correct order for each set of cards from least to greatest.

Solution:

a. [tex]\sqrt{0.25},\sqrt{\dfrac{1}{9}},\dfrac{6}{25}[/tex]

Convert all numbers in decimal form.

[tex]\sqrt{0.25}=0.5[/tex]

[tex]\sqrt{\dfrac{1}{9}}=\dfrac{1}{3}=0.333...[/tex]

[tex]\dfrac{6}{25}=0.24[/tex]

It is clear that,

[tex]0.24<0.33...<0.5[/tex]

[tex]\dfrac{6}{25}<\sqrt{\dfrac{1}{9}}<\sqrt{0.25}[/tex]

Therefore, the required order is [tex]\dfrac{6}{25},\sqrt{\dfrac{1}{9}},\sqrt{0.25}[/tex].

b. [tex]\sqrt{\dfrac{121}{25}},2.25,\sqrt{5}[/tex]

Convert all numbers in decimal form.

[tex]\sqrt{\dfrac{121}{25}}=\dfrac{11}{5}=2.2[/tex]

[tex]2.25[/tex] already in decimal form.

[tex]\sqrt{5}\approx 2.236[/tex]

It is clear that,

[tex]2.2<2.236<2.25[/tex]

[tex]\sqrt{\dfrac{121}{25}}<\sqrt{5}<2.25[/tex]

Therefore, the required order is [tex]\sqrt{\dfrac{121}{25}},\sqrt{5},2.25[/tex].

Answer:

8 pieces of wood should be put along each side of the chessboard

Step-by-step explanation:

Here in this question, we are interested in knowing the the number of pieces of wood that should be put along each side of the cheese board.

Firstly, to know the number of pieces of wood to use, we need to divide the area of the board by the area of each piece of wood

Mathematically that would be 64 square inches/ 1 square inch = 64 pieces of wood

64 pieces of wood would be needed to complete the cheeseboard.

The number of pieces to put along each side of the cheese board will be √64.

This is because the shape of a chessboard is square.

Thus the number of pieces to put on each side will be √64 = 8
