Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?

Answers

The statement that best explains why Maricella's strategy is incorrect based on the distribution property and order of operation is option A.

Recall:

When given an equation involving brackets, the distribution property must be applied first which involves multiplying every term in a bracket by the term outside the bracket.

In the equation given, to solve for x, Maricella needs to apply the distribution property by using -2 to multiply each term in (3x - 4) and using +3 to multiply every term in (x + 1).

The next step will now be addition and subtraction of like terms.

Therefore, the statement that best explains why Maricella's strategy is incorrect based on the distribution property and order of operation is option A.

Step-by-step explanation:

if the first and fifteen terms of A.P. are 8 and -48 respectively, obtain the progression​

Answers

Answer:

8, 4, 0, -4, - 8, .........

Step-by-step explanation:

The n the term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 8 and a₁₅ = - 48, then

8 + 14d = - 48 ( subtract 8 from both sides )

14d = - 56 ( divide both sides by 14 )

d = - 4

To obtain the progression subtract 4 from each term, that is

8, 4, 0, - 4, - 8, ......

Answer:

8, 4, 0, -4, -8, -12, -16, -20,...

Step-by-step explanation:

Arithmetic Progressions

The general term of an arithmetic progression (A.P.) is:

[tex]a_n=a_1+(n-1).r[/tex]

Where:

a1  = First term

an = Term number n

n   = Number of the term

r   = Common difference

We are given: a1=8, and a15=-48, n=15. Calculate r:

[tex]\displaystyle r=\frac{a_n-a_1}{n-1}[/tex]

[tex]\displaystyle r=\frac{-48-8}{15-1}[/tex]

[tex]\displaystyle r=\frac{-56}{14}[/tex]

r = -4

We can get the terms of the progression by subtracting 4 to the previous term.

Thus, the first terms of the progression are:

8, 4, 0, -4, -8, -12, -16, -20,...

2) {6,8,14}
3) {7, 22, 30}
4) {7, 21, 30}

Answers

Answer:

NONE

Step-by-step explanation:

You have to do a² + b² = c²

To do it you have to put the three numbers from least to greatest for it to work. They already are so that's good.

15² + 23² = 37² (solve)

225 + 529 = 1369

754 ≠ 1369

6² + 8² = 14² (solve)

36 + 64 = 196

100 ≠ 196

7² + 22² = 30²

49 + 484 = 900

433 ≠ 900

7² + 21² = 30²

49 + 441 =  900

490 ≠ 900

I don't know what happened, but none of these would work.

I even used a pythagorean theorem calculator to check my work and none of them match.

The function f and g are such that f(x) =2x + 5 /(x -4) and g(x) = 2x – 3 Calculate the value of(i) g(4) (ii) fg(2) (iii) gˉ¹(7)​

Answers

Answer:

g(4) = 5, fg(2) = 7/-3, gˉ¹(7)​ = 2

Step-by-step explanation:

i.) g(4)= 2(4) -3

g(4) = 8 -3

g(4) = 5

ii.) fg(2)

g(2) = 2(2)-3

g(2)= 4-3

g(2) = 1

fg(2) = 2(1)+5/1-4

fg(2) = 7/-3

iii.) g(x) = 2x -3

g(y) = 2y -3

x = 2y -3

x-3 = 2y

y= (x-3)/2

gˉ¹(7)​ = ((7)-3)/2

gˉ¹(7)​ = 4/2

gˉ¹(7)​ = 2

∀x∀y(((x ≥ 0) ∧ (y < 0)) → (x – y > 0))
A. A non-negative number - a negative number is positive.
B. For any two real numbers, the first is non-negative, the second is negative, and the difference is positive.
C. For every non-negative number, one can find a negative number so that the first number minus, the second is positive.
D. One can find a non-negative number and a negative number so that the first minus, the second is positive.
E. One can find a non-negative number so that for any positive number chosen, the first number minus, the second is positive.

Answers

Answer:

B. For any two real numbers, the first is non-negative, the second is negative, and the difference is positive.

Step-by-step explanation:

To answer this question, I'll analyse the mathematical statements one at a time

The analysis is as follows:

∀x -> This means real number x

∀y -> This means real number y

(x ≥ 0) -> Such that real number x is greater than or equal to 0. In other words, x is positive

∧ -> and

(y < 0)-> y is less than 0. In other words, y is negative

So, there are two real numbers: x and y

→ (x – y > 0) -> Their difference is greater than 0. In other words, their difference is positive

When the analysis above is compared to the list of given options; the option that match is B.

Hence, option B answers the question.

week?

not multi choice u type an answer !!!

Answers

Commision would be $490
3500 times .14 is 490

So the commission would be determined by multiplying the total profit of goods sold by the percent. With that we do this, 3,500*0.14=490$.
So, He would make a 490$ commission if he sold 3,500$ last week.

john is 2 years younger than his sister, annie. Last year, John was half Annie's age. How old are john and Annie now?

Answers

Answer:

John is 3 and Annie is 5 because to be half of someone's age while being to years younger it would have to be 2 and 4 - but then a year passed and so the are now 3 and 5.

Step-by-step explanation:

The present  age of John is  3 years

The present age of Annie is 5 years  

Given that John is 2 years younger than Annie's age

Let the present age of John be "J"

Let the present age of Annie be "A"

According to the given situation

[tex]\rm J = A -2........(1)\\[/tex]

One year ago the age of John = [tex]\rm J-1[/tex]

One year ago the age of Annie = [tex]\rm A -1[/tex]

According to the given situation

[tex]\rm\dfrac{A-1}{2}= J-1.........(2)[/tex]

On solving for equations (1) and (2) we get

A = 5 and J = 3

So the present  age of Annie is  5 years

The present age of John is 3 Years

(PLEASEEE HELP I DONT UNDERSTAND) Which of the following equations represents a linear NON-proportional function?
A) y=3x+0
B) y=x/4
C) y=7x
D) y=2/5x+7

Answers

D

A nonproportional relationship is a linear line that doesn’t go through the origin.

y=3x+0 does go through the origin because the y-intercept (the b) is 0

Y=x/4 also has a y-intercept of 0

Y=7x also has a y-intercept of 0.

y=2/5x+7 does not go through the origin because the line passes the y-axis at (0,7) which is the y-intercept.
