Answer:
1 / 3^5
1/ 243
Step-by-step explanation:
3^4 ÷ 3^9
We know that a^b ÷ a^c = a^ ( b-c)
3 ^ ( 4-9)
3^ -5
We can rewrite this as a^-b = 1/ a^b
1 / 3^5
We know that 3^5 = 243
1/ 243
Answer:
7x−y=7 (x= 1 y/7)

Answer:
A secant line contains a chord always
Step-by-step explanation:
A line intersecting in two points is called a secant line, in one point a tangent line and in no points an exterior line. A chord of a circle is the line segment that joins two distinct points of the circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord.
(-6, 6) (6, 2)
lets looks at the y's 6 and 2 what the distance between them? -4
lets looks at the x's -6 and 6 what the distance between them? 12
so slope is -4/12 or -1/3
