Drag the tiles to the correct boxes to complete the pairs. Match each system of inequalities to the graph representing its solut
mojhsa [17]

The solutions to the systems of inequalities are (0.3, 1.3), (-1, -2), (0.4, 1.8) and (3.6, 0.8)

<h3>How to determine the solution to the systems?</h3>

The graph of the systems of inequalities is not given.

So, I would plot a new graph to answer this question.

The systems of inequalities are given as:

y − x > 1 and 2x + y ≤ 2

x + y ≥ -3 and 5x – y ≤ -3

2x – y ≤ -1 and x + 2y < 4

4x – 3y < 12 and x + 3y ≥ 6

Next, we plot these inequalities on a graph and write out the points of intersection.

From the attached graph, we have:

y − x > 1 and 2x + y ≤ 2  ⇒ (0.3, 1.3)

x + y ≥ -3 and 5x – y ≤ -3  ⇒ (-1, -2)

2x – y ≤ -1 and x + 2y < 4  ⇒ (0.4, 1.8)

4x – 3y < 12 and x + 3y ≥ 6 ⇒ (3.6, 0.8)

Hence, the solutions to the systems of inequalities are (0.3, 1.3), (-1, -2), (0.4, 1.8) and (3.6, 0.8)

A line has a slope of 1 and passes through the point (-8, -7). What is its equation in
AlekseyPX

Answer: y = x + 1

Step-by-step explanation:

y = 1x + c

-7 = 1(-8) + c

-7 = -8 + c

-7 + 8 = c

1 = c

y = 1x + 1 or

y = x + 1

kaheart [24]

Answer:

The given expression is a cubic polynomial with degree 3.

Step-by-step explanation:

We are given the following in the question:

3x^3-x^2

Polynomial:

  • A polynomial is an expression.
  • It  consisting of variables and coefficients.
  • The variables and coefficients involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Since, the given expression satisfies all the properties, it is a polynomial.

Degree of polynomial:

  • It is the maximum degree of the polynomial.

The degree of given polynomial is 3.

Nature of polynomial:

It is a cubic polynomial.
