Answer:
x=1
Step-by-step explanation:
if it is truly 9^(x-1)=27^(x-1), then you dont really need to use the quadratic fromula.

Answer:
The transformation is " a horizontal translation 4 units to the right " ⇒ (d)
Step-by-step explanation:
Let us revise the translation of a function
- 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)
- If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
- If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
Let us look at the graph and choose some points on the f(x) and find their images on y
∵ Point (1, 2) lies on f(x)
∵ Point (5, 2) lies on y
∵ Point (3, 8) lies on f(x)
∵ Point (7, 8) lies on y
→ There is no change in the y-coordinates of the points, the change
only in the x-coordinates
∴ The translation is horizontally
∵ 5 - 1 = 4 units ⇒ positive value means to right
∴ f(x) is translated 4 units to the right
∴ The answer is " a horizontal translation 4 units to the right " (d)
The length of the sides of the triangle are; RS =√5, ST= √17 and RT=√18, their slopes in the same order are; (1/2), -4 and -1.
<h3>What is the slope about?</h3>
The length of each side can be solve for by the following ways;
Side RS = √((4-2)² + (4-3)²) = √5
Side ST = √((5-4)² + (0-4)²) = √17
Side TR = √((5-2)² + (0-3)²) = √18
The slopes can be examined as;
Slope RS = (4-3)/(4-2) = 1/2
Slope ST = (0-4)/(5-4) = -4
Slope TR = (0-3)/(5-2) = -1.
Therefore, one can say that triangle RST into one of three types of triangles:
- Scalene
- Isosceles
- Equilateral
