Answer: a)12
Step-by-step explanation:
the triangle is equilateral meaning that all sides have the same length so,
3x+8 = 4x-4
3x-4x=-4-8
-x=-12
x=12
Answer:
- x= 10-6y+y²
Step-by-step explanation:
|x-1|=3-y
(|x-1|)²=(3-y)²
x-2x+1=9-6y+y²
-x=9-6y+y²+1
The graph of f(x) is stretched vertically by scale factor 3 and translated 2 units to the right to give the graph of 3f(x - 2)²
Step-by-step explanation:
Let us revise the vertical stretch and the horizontal translation
- A vertical stretching is the stretching of the graph away from the x-axis
- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched by multiplying each of its y-coordinates by k.
- If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
- If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
∵ f(x) = x²
∵ f(x) is multiplied by 3
- 3 is greater than 1, then the graph of f(x) is stretched vertically
by scale factor 3
∴ The graph of f(x) is stretched vertically by scale factor 3
∵ x² is changed to (x - 2)²
- That means the graph of f(x) translated 2 units to the right
∴ The graph of f(x) is translated 2 units to the right
The graph of f(x) is stretched vertically by scale factor 3 and translated 2 units to the right to give the graph of 3f(x - 2)²

Answer:
3/4
Step-by-step explanation:
To do this you find a highest common factor that goes into both. With that being said, it would be 3.
9/12 = 3/4
