Answer:
(3x-2)(x+4y)
Step-by-step explanation:
3x^2-2x+12xy-8y
3x^2+12xy=3x(x+4y)
-2x-8y=-2(x+4y)
3x^2-2x+12xy-8y=3x(x+4y)-2(x+4y)
(3x-2)(x+4y)
Answer:
The answer to your question is the letter B. y = -1/2x - 1
Step-by-step explanation:
Data
A (-6, 2)
slope = m = -1/2
Formula
y - y1 = m(x - x1)
x1 = -6 y1 = 2
Substitution
y - 2 = -1/2(x + 6)
Expand
y - 2 = -1/2x - 6/2
Simplify
y - 2 = -1/2x - 3
Solve for y
y = -1/2x - 3 + 2
Result
y = -1/2x - 1
Answer:
Step-by-step explanation:
x=3y+2 ⇔ x - 2 = 3y ⇔ y = (x - 2)/3
Answer:
A
Step-by-step explanation:
we can find using the trigonometric formulas
we can find y by using cosine.
cos = adj / hyp
cos 60 = y / 10
y = 10 cos 60
y = 5
now we can use the Pythagorean theorem since we have the base and hyp
a² + b² = c²
5² + b² = 10²
25 + b² = 100
b² = 75
b = 5√3
