Answer:
{(3^-1)(5^2)/(3^2)(5^-4)}^1/3= 25/3
Step-by-step explanation:
(3^-1)(5^2)/(3^2)(5^-4)
=(5^6/3^3)^1/3
=(5^6/27)^1/3
=∛5^6/27 (find the cube root)
=5^2/3
=25/3
Answer:
x≤9
Step-by-step explanation:
x−6≤3
Add 6 to both sides of the inequality.
x≤3+6
Add 3 and 6.
x≤9
Hope this helps! Plz mark as brainliest! :)
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
Answer:
90°
Step-by-step explanation:
Actually the question should be AC is tangent to circle B at point C. What is the measure of angle BCA.
AC is tangent and BC is radius.
Radius is perpendicular to the tangent.
Therefore,
measure of angle BCA = 90°
