The addition of the polynomials x⁴ - 3x + 1, 4x² - 2x + 8, x³ - 9 in descending powers of x is x⁴ + x³ + 4x² - 5x.

<h3>Polynomial</h3>

  • x⁴ - 3x + 1
  • 4x² - 2x + 8
  • x³ - 9

Adding the polynomial

(x⁴ - 3x + 1) + (4x² - 2x + 8) + (x³ - 9)

  • Open parenthesis

= x⁴ - 3x + 1 + 4x² - 2x + 8 + x³ - 9

  • Collect like terms in descending powers

= x⁴ + x³ + 4x² - 3x - 2x + 1 + 8 - 9

= x⁴ + x³ + 4x² - 5x

Therefore, the addition of the polynomials x⁴ - 3x + 1, 4x² - 2x + 8, x³ - 9 in descending powers of x is x⁴ + x³ + 4x² - 5x.

Which system of equations is represented by the graph?
ahrayia [7]

The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that the quadratic function intersecting a linear function at points (1, 0) and (3, 4)

This means that this points lie on both functions.

y = x² - 2x + 1 and 2x - y = 2

For point (1, 0):

y = 1² - 2(1) + 1 = 0; 2(1) - 0 = 2

For point (3, 4):

y = 3² - 2(3) + 1 = 4; 2(3) - 4 = 2

The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)
