Create a system of linear equations with one solution. In your final answer, include the system of equations and the graphs of t

GrogVix [38]

Answer:

<u>System of equations</u>

$x + y = 5$

$y - 2x = -4$

$(x,y) = (3,2)$ --- solution

See attachment for graph

Step-by-step explanation:

Solving (a): Linear equations with 1 solution

The only condition to this is that, the system must have 1 solution.

Other than that, there is no other condition.

A linear equation is represented as:

$ax + by= c$

For the equation to have 1 solution;

$a_1 * b_2 \ne a_2 * b_1$

And example of such equation is:

$x + y = 5$

$y - 2x = -4$

Solving (b): The graph

See attachment for graph

The solution is the point of intersection of both lines of the graph. So, we have:

$(x,y) = (3,2)$

Which is the polynomial function of lowest degree with rational real coefficients, a leading coefficient of 3 and roots StartRoo

NNADVOKAT [17]

The polynomial function of lowest degree is 3x³ - 6x² - 15x + 30. Then the correct option is A.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

The polynomial function of lowest degree with rational real coefficients, a leading coefficient of 3 and ±√5 and 2.

The roots of the polynomial are ±√5 and 2 with a leading coefficient of 3.

Then f(x) will be given as

f(x) = 3(x + √5)(x - √5)(x - 2)

On simplifying, we have

f(x) = 3(x + √5)(x - √5)(x - 2)

f(x) = 3(x² - 5)(x - 2)

f(x) = 3(x³ -2x² - 5x + 10)

f(x) = 3x³ - 6x² - 15x + 30

The polynomial function of lowest degree is 3x³ - 6x² - 15x + 30. Then the correct option is A.

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5). Describe the ste

olga_2 [115]

1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.

2. So f(x)= $(x-a)^{3}$

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions:

$f(x)=b(x-a)^{3}$

4. Now, f(0)=-5 so $-5=f(0)=b(0-a)^{3}=b(-a) ^{3}=-ba ^{3}$

$-5=-ba ^{3}$

$5=ba ^{3}$

$b= \frac{5}{ a^{3} }$

5. the function is $f(x)=\frac{5}{ a^{3} }(x-a)^{3}$ where a can be any real number except 0
