Answer:
Yes
Step-by-step explanation:
It's 29/7 or 4 and 1/7 as the mixed number
To see if an ordered pair is a solution to an inequality, plug it into the inequality and simplify. If you get a true statement, then the ordered pair is a solution to the inequality. If you get a false statement, then the ordered pair is not a solution.
Answer: ↴
Length of Segment XY =>9 cm
Now We have to check options
YZ=>9 cm ( It can be true if XYZ is assumed to be isosceles triangle)
XZ=> 9 cm ( Same It also can be true if XYZ is assumed to be isosceles triangle)
XZ=>973 cm or 9.73 cm ( not clearly specified in question) But it is possible as Two sides can be taken of any length )
XZ= 2XY Again It is also possible
YZ is longest side In triangle There should be longest side if it is not equilateral.
So , XZ= 2XY and YZ is longest side are more accurately possibilities of triangle XYZ
Im not sure on the syntax here, but i assume the question is (4/9)^-1
(4/9)^-1
= (4^-1)/(9^-1)
A negative power is an inverse of the positive power
i.e. x^-2 = 1/x^2
This is because if we have say x^3/x^5 we simplify it by cancelling x^3 which gives 1/x^2.
Another way to think of it is to subtract the power of the bottom x from the power of the top x: 3-5 = -2 so x^3/x^5 = x^-2.
I hope this explains how negitive powers are the inverse of the positive power.
So....
(4^-1)/(9^-1)
= 9/4
Because the inverse of 4 is 1/4 and the inverse of 1/9 is 9
