Answer:

The goal of solving two-step equations is to isolate the variable (get it by itself) and solve for the value using the following steps:

1. Add or subtract the constant term from both sides of the equation.

2. Multiply or divide the coefficient from both sides of the equation.

Step-by-step explanation:

Solving equations means using inverse (opposite) operations.

subtraction - addition

multiplication - division

In order to get the variable by itself, you need to first get rid of the constant (the number by itself) by adding or subtracting from both sides of the equal sign. Then, you multiply or divide by the coefficient of the variable to solve for the variable.

Express the polynomial below by nesting. f(x)=4x³+3x²+2x-4

BabaBlast [244]

Answer:

$f(x)=4x^{3} +3x^{2} +2x-4$ can be expressed in nested form as $((4x+3)x+2)x-4$

Step-by-step explanation:

Considering the polynomial

$f(x)=4x^{3} +3x^{2} +2x-4$

Expressing the polynomial by nesting

So,

$f(x)=4x^{3} +3x^{2} +2x-4$

Step 1) Writing down the coefficient and one factor of x from the first term and add on the coefficient of the next term.

$4x+3$

Step 2) Enclose this term in brackets, multiply by x and add on the next coefficient.

$(4x+3)x+2$

Step 3) Repeating the previous step until all terms are within the equation.

So,

$((4x+3)x+2)x-4$

Therefore, $f(x)=4x^{3} +3x^{2} +2x-4$ can be expressed in nested form as $((4x+3)x+2)x-4$

Which of the following is not a requirement for regression analysis? Choose the correct answer below. A. Outliers can have a st

yKpoI14uk [10]

Answer:

Option D is correct.

Step-by-step explanation:

Regression analysis determines the relationship between 2 or more variables by examining the influence of independent variables on a dependent variable.

Few requirements for regression analysis are like - quantitative data condition, the outlier condition, error independence etc.

The following is not a requirement for regression analysis:

D:The method for regression analysis line is not robust. It is seriously affected by a small departure from a normal distribution.

SOMEONE, PLEASE HELP ME OUT!!!!!! WILL MARK BRAINLIEST

Hitman42 [59]

Answer:

see below

Step-by-step explanation:

19. (4x + 8x² - 8) + (x² + 7 - 4x)

= 4x + 8x² - 8 + x² + 7 - 4x

= 8x² + x² + 4x - 4x -8 + 7

20. (7x² - 11 + 16x) + (5x - 3x² - 7)

= 7x² - 11 + 16x + 5x - 3x² - 7

22. (4x² - 12x - 10) - (2x² + x - 3)

= 4x² - 12x - 10 - 2x² - x + 3

23. (7x³ - 9x² - 14x) - (4x³ - 4 - x)

= 7x³ - 9x² - 14x - 4x³ + 4 + x

= 7x³ - 4x³ - 9x² - 14x + x + 4

25. (9x² + 24x - 8) - (5x² + 3x + 10)

= 9x² + 24x - 8 - 5x² - 3x - 10

26. (5x - 12x² + 9x³) - (5x³ + 6x - 3)

= 5x - 12x² + 9x³ - 5x³ - 6x + 3

28. (2x² - 1 + 3x³) + (5 - 13x - 11x²)

= 2x² - 1 + 3x³ + 5 - 13x - 11x²

30. (10x - x² + 8) + (5x² + 1 - 22x)

= 10x - x² + 8 + 5x² + 1 - 22x

Find the product (4x-5y)^2

sleet_krkn [62]

To find the product of (4x-5y)^2,
we can rewrite the problem as:
(4x-5y)(4x-5y) (two times because it is squared)

Now, time to use that old method we learned in middle school:
FOIL. (Firsts, Outers, Inners, and Lasts)

FOIL can help us greatly in this scenario.
Let's start by multiplying the 'Firsts' together:
4x * 4x = <em>16x^2</em>

Now, lets to the 'Outers':
4x * -5y = <em>-20xy</em>

Next, we can multiply the 'Inners':
-5y * 4x = <em>-20xy</em>

Finally, let's do the 'Lasts':
-5y * -5y = <em>25y</em>^2

Now, we can take the products of these equations from FOIL and combine like terms. We have: 16x^2, -20xy, -20xy, and 25y^2.
-20xy and -20xy make -40xy.

The final equation (product of (4x-5y)^2) is:
16x^2 - 40xy + 25y^2

Hope I helped! If any of my math is wrong, please report and let me know!
Have a good one.
