Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

Step-by-step explanation:

4) Jamie is 5 years older than Ella. Jamie's age is 11 years less than three times Ella's age. Write a system of equations to model the relationship between Jamie's age and Ella's age. Let j = Jamie’s age Let e = Ella’s age
HINT: You should have TWO equations; create one for each sentence description above.
Equation 1: j =
Equation 2: j =

Answers

The system of equations is j = e + 5 and j = 3e - 11 we can solve it using the substitution method.

What is linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Jamie is 5 yearsolder than Ella. Jamie's age is 11 years, less than three times Ella's age.

The system of equation can be written as:

j = e + 5

j = 3e - 11

Thus, the system of equations are j = e + 5 and j = 3e - 11 we can solve it using the substitution method.

j = e + 5
j = 3e - 11 equations

there are different ways of expressing the same value examlpe . 10 = 4 + 6 and 10 = 8 + 2 and 10= 7 + 3 4 + 6 = 8 + 2 =7 + 3 all = 10
using the concept same applies to varibles j = j so, e + 5 = 3e - 1 so, the possible answer would be e + 5 = 3e - 11 to find the value of e .

Which polynomials are prime? Check all that apply.15x2 + 10x – 9x + 7
20x2 – 12x + 30x – 18
6x3 + 14x2 – 12x – 28
8x3 + 20x2 + 3x + 12
11x4 + 4x2 – 6x2 – 16

Answers

Prime polynomials are those polynomials that are not factored into lower degree polynomial. The options that are prime polynomials are 1), 4), and 5).

Evaluate all options in order to check that the polynomials are prime or not:

1). $15x^2 +10x -9x+7$

5x(3x + 2) - (9x - 7)

So, this polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

2). $20x^2-12x+30x-18$

$4x(5x - 3)+6(5x-3)$

(4x + 6)(5x - 3)

So, this polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.

3). $6x^3+14x^2-12x-28$

$2x^2(3x+7)-4(3x+7)$

$(2x^2-4)(3x+7)$

So, this polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.

4). $8x^3+20x^2+3x+12$

$4x^2(2x+5)+(3x+20)$

So, this polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

5). $11x^4+4x^2-6x^2-16$

$x^2(11x^2+4)-2(3x^2+8)$

So, this polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

Answer:

The prime polynomials are 1, 4 and 5

Step-by-step explanation:

Given some polynomials we have to classify the polynomials prime or not.

Prime polynomials are the polynomial with integer coefficients that cannot be factored into lower degree polynomials.

$15x^2 + 10x - 9x + 7$

⇒ $5(3x+2)-(9x-7)$

can't be factored into lower degree polynomial ∴ prime polynomial.

$20x^2 - 12x + 30x - 18$

⇒ $4x(5x-3)+6(5x-3)$

⇒ $(4x+6)(5x-3)$

hence, not a prime polynomial.

$6x^3 + 14x^2 - 12x - 28$

⇒ $2x^2(3x+7)-4(3x+7)$

⇒ $(2x^2-4)(3x+7)$

hence, not a prime polynomial.

$8x^3 + 20x^2 + 3x + 12$

⇒ $4x^2(2x+5)+(3x+20)$

can't be factored into lower degree polynomial ∴ prime polynomial.

$11x^4 + 4x^2 - 6x^2 - 16$

⇒ $x^2(11x^2+4)-2(3x^2+8)$

can't be factored into lower degree polynomial ∴ prime polynomial.

The prime polynomials are 1, 4 and 5

saidhari bought a toaster oven for $75 this price was 1/4 off the list price. what was the list price

Answers

The total price would have to be $300 , only because if you find the recipocal of 1/4 which is (4) you multiply it by the cost you bought it at which is $75 . So you get $300.

Final answer:

The list price of the toaster oven is $100.

Explanation:

To calculate the list price of the toaster oven, we need to find the original price before the 1/4 discount. Let's represent the list price as 'x'. Since the sale price is $75 and it is 1/4 off the list price, we can set up the equation: x - (1/4)x = $75. Simplifying this equation, we have: 3/4x = $75. To solve for x, we multiply both sides of the equation by the reciprocal of 3/4, which is 4/3: x = $75 × 4/3. Therefore, the list price of the toaster oven is $100.
