If f(x) = -4x + 3 and g(x) = 3x^2 + 2x - 4 find (f+g) (x)

Answers

Answer:

3x^2-2x-1

Step-by-step explanation:

Here, we want to find (f + g)(x)

Mathematically, that will be f(x) + g(x)

work out 1/2 x 7 giving your answer as a mixed number

Answers

Answer:

[tex]4\frac{1}{2}[/tex]

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»»  [tex]\frac{1}{2}[/tex] of 7  OR  7 ÷ 2

So, just solve using either one and you’ll get 4.5 or [tex]4\frac{1}{2}[/tex]. But since the question wants the answer to be a mixed number, then choose [tex]4\frac{1}{2}[/tex].

Two random samples of 25 people were asked how many 12-ounce cans of soda they consume each week. The first sample contained both males and females, aged 12-19. The second sample contained both males and females, aged 20-39. The results are shown in the table below. Using complete sentences, make one inference comparing the two groups, and explain your reasoning.

Answers

Answer:

One inference that can be made is that the age group of 12-19 consume more sodas than the age group of 20-39.

Step-by-step explanation: ok sooooo

The required individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19.

What is mathematical reasoning?

Mathematical reasoning is the process of using logical thinking and mathematical concepts to solve problems, prove theorems, and develop mathematical models. It involves identifying patterns, making conjectures, and using deductive reasoning to arrive at logical conclusions based on given assumptions.

Based on the information given in the table, it can be inferred that individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19. This inference can be made because the mean and median values of the second sample (aged 20-39) are higher than those of the first sample (aged 12-19). Specifically, the mean for the second sample is 8.6 cans of soda per week, while the mean for the first sample is 6.96 cans of soda per week. Similarly, the median for the second sample is 8 cans of soda per week, while the median for the first sample is 5 cans of soda per week.

Question 3: Jason
receives $40 from
selling 5 adult tickets
and 8 students tickets.
.write an equation to
represent the situation.

Answers

Answer:

$40 = 5a + 8s

Step-by-step explanation:

For this question all we need to know is that $40 is equal to 5 prices of the adult tickets plus the 8 prices of the student tickets. From here we can just give a variable to each price and make an equation, like so

Let "a" be the price of the adult ticket and

Let "s" be the price of the adult ticket, then....

$40 = 5a + 8s

(Just to make sure you understand I will repeat. 5 comes from he fact hat there were 5 adult tickets sold which means that there is 5 adult ticket prices in the $40, and exactly the same reasoning goes for the student tickets, 8 students tickets were sold which means the is 8 prices of the student ticket inside the $40.)

John is buying food for his cat, Fluffy. Fluffy LOVES a fancy wet food which costs $1.50 per day. Fluffy will also tolerate dry food which is $0.75 per day. John wants to spend at most $9.00 on cat food each week

Answers

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.

Hence:

x + y = 7                    (1)

Also, John wants to spend at most $9.00 on cat food each week. Hence:

1.5x + 0.75y ≤ 9       (2)

The list of possible points after solving graphically are:

(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:

2. 9m + 2[tex]\sqrt{n}[/tex]

3. 6a

4. (5a - 3b)[tex]\sqrt{5y}[/tex]

Step-by-step explanation:

1. since a and c share the same squareroot x, you can combine these together.

2. First add like terms together. 4m - m + 6m = 9m. Then 5[tex]\sqrt{n}[/tex] and -3[tex]\sqrt{n}[/tex] combined equals 2[tex]\sqrt{n}[/tex]

3. First simplify the square roots. squareroot of 16 is 4. square root of 49 is 7. square root of 81 is 9. They are all multiplied by a in the expression. Thus 4a - 7a + 9a = 6a

4. First simplify the radicals, they are not perfect. square root of 125 is equivalent to sqrt(25 * 5), which sqrt of 25 is 5, but we keep the sqrt of 5. For sqrt of 45, it is the same as sqrt9 * sqrt5. sqrt of 9 is the same as 3 and we keep sqrt 5. Thus we get the below:

5a[tex]\sqrt{5y}[/tex] - 3b[tex]\sqrt{5y}[/tex]

We can combine the two like terms and get the final answer above.

Step-by-step explanation:

We assume that point X is the intersection point of the medians. Then ...

  MQ = 3XQ

  3x -3 = 3(2x -6)

  3x -3 = 6x -18 . . .  eliminate parentheses

  15 = 3x . . . . . . . . . add 18-3x

  5 = x . . . . . . . divide by 3

  XQ = 2x -6 = 2(5) -6

  XQ = 4
