1 answer:
Elodia [21]3 years ago
6 0

Answer:

2

Step-by-step explanation:

We are asked to perform the subtraction

x² + xy - 3y² - (5x² - xy + y²) ← distribute the parenthesis by - 1

= x² + xy - 3y² - 5x² + xy - y² ← collect like terms

= (x² - 5x²) + (xy + xy) + (- 3y² - y² )

= - 4x² + 2xy - 4y²

Find 50% of 36:<br> Find 25% of 36:<br> Find 75% of 36:
HACTEHA [7]

Answer:

18, 9, 27

Step-by-step explanation:

36 ÷ 2 = 18. Dividing by 2 is the same as multiplying by 50%.

36 ÷ 4 = 9. Dividing by 4 is the same as multiplying by 25%.

Since 25% • 3 = 75%, you can do 9 (from previous) • 3 to get 27.

const2013 [10]

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\spadesuit\; Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

Given Points are (1 , 7) and (-4 , -8)

here x₁ = 1 and x₂ = -4 and y₁ = 7 and y₂ = -8

\spadesuit\; Slope(m) = \frac{7 + 8}{1 + 4} = \frac{15}{5} = 3
