Answer:
-36 = k
Step-by-step explanation:
-3 = k/12
Multiply each side by 12
-3*12 = k/12 *12
-36 = k
Answer:
1. A resposta é a opção C.
2. ( a +b )² = a² + 2ab + b² Verdade
( a - b )² = a² - 2ab + b² Verdade
( a + b ) .( a – b) = a² + b² Falso
( a +b)³ = a³ + 3a²b + 3ab² + b³ Verdade
( a -b)³ = a³ - 3a²b + 3ab² - b³ Verdade
3. a.) m² - 14am + 49a² = ( m - 7a)²
b) m2 – 9n² = m² - (3n)² = (m + 3n)(m - 3n)
c) 30+ 5xy + 12a +2axy = (6 + xy)(5 + 2a)
d) 8a²b + 10ab² = 2ab( 4a + 5b)

<h2>
Answer: y - 2 = - ¹/₅ ( x - 3 )</h2>
Step-by-step explanation:
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (3 - 2) ÷ ( -2 - 3)
= - ¹/₅
We can now use the point-slope form to write the equation for this line:
y - y₁ = m(x - x₁)
y - 2 = - ¹/₅ ( x - 3 )
Answer:
<em>y = 9x + 2</em>
Step-by-step explanation:
The equation of a line with slope m and y-intercept b is
y = mx + b
If you were asked to write the equation of the line with slope = 9 and y-intercept = 2, then the equation is
y = 9x + 2
