What is 8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³ in standar form?
vovangra [49]

The expression in standard form is n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶

<h3>How to express in standard form?</h3>

The expression is given as:

8mn⁵-2m⁶+5m²n⁴-m³n³+n⁶-4m⁶+9m²n⁴-mn⁵-4m³n³

Collect the like terms

8mn⁵ -mn⁵ - 2m⁶ -4m⁶ + 5m²n⁴ +9m²n⁴+n⁶ - 4m³n³ - m³n³

Evaluate the like terms

7mn⁵ - 6m⁶ + 14m²n⁴+n⁶ - 5m³n³

Rewrite in standard form

n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶

Hence, the expression in standard form is n⁶ + 7mn⁵ + 14m²n⁴ - 5m³n³ - 6m⁶

Answer the equation
ivanzaharov [21]

Answer:

x = -2, y = -4

coordinate: (-2, -4)

Step-by-step explanation:

Given system of equations:

a) 4x - 7y = 20

b) x - 3y = 10

1. Make x the subject in the <em>second</em> equation:

⇒ x - 3y = 10 [add 3y to both sides]

⇒ x - 3y + 3y = 10 + 3y

⇒ x = 3y + 10

2. Substitute the given value of x into <em>first</em> equation:

⇒ 4x - 7y = 20

⇒ 4(3y + 10) - 7y = 20 [distribute 4 through the parentheses]

⇒12y + 40 - 7y = 20 [combine like terms]

⇒ 5y + 40 = 20 [subtract 40 from both sides]

⇒ 5y - 40 - 40 = 20 - 40

⇒ 5y = -20 [divide both sides by 5]

⇒ 5y ÷ 5 = -20 ÷ 5

⇒ y = -4

3. Find the value of x by substituting the given value of y into x = 3y + 10:

⇒ x = 3y + 10

⇒ x = 3(-4) + 10 [multiply]

⇒ x = -12 + 10 [add]

⇒ x = -2

4. Check your work:

<em>a) 4x - 7y = 20</em>

⇒ 4(-2) - 7(-4) = 20

⇒ -8 + 28 = 20

⇒ 20 = 20 ✔

<em>b) x - 3y = 10</em>

⇒ -2 - 3(-4) = 10

⇒ -2 + 12 = 10

⇒ 10 = 10 ✔

This system of equations has a solution at (-2, -4).

The parabola y=ax^2+bx-10 passes through the points (4.5,8) and (-2.5, 15). Determine the values of a and b
yuradex [85]
y=ax^2+bx-10 \\ \\&#10;(4.5,8) \\&#10;8=a \times 4.5^2 + b \times 4.5-10 \\&#10;8=20.25a+4.5b-10 \ \ \ |+10 \\&#10;18=20.25a+4.5b \\ \\&#10;(-2.5,15) \\&#10;15=a \times (-2.5)^2+b \times (-2.5)-10 \\&#10;15=6.25a-2.5b-10 \ \ \ |+10 \\&#10;25=6.25a-2.5b

The system of equations:
18=20.25a+4.5b \ \ \ |\times 5 \\&#10;25=6.25a-2.5b \ \ \ |\times 9 \\ \\&#10;90=101.25a+22.5b \\&#10;\underline{225=56.25a-22.5b} \\&#10;90+225=101.25a+56.25a \\&#10;315=157.5a \ \ \ |\div 157.5 \\&#10;a=2 \\ \\&#10;25=6.25a-2.5b \\&#10;25=6.25 \times 2-2.5b \\&#10;25=12.5 -2.5b \ \ \ |-12.5 \\&#10;12.5=-2.5b \ \ \ |\div (-2.5) \\&#10;b=-5 \\ \\&#10;\boxed{a=2} \\ \boxed{b=-5} \\ \boxed{y=2x^2-5x-10}
