Answer:
6
Step-by-step explanation:
Draw line segments ST and RQ. Triangle RUQ and SUT are similar, because they are in a circle. Now, you use similar triangles to get that QU/UT=RU/SU so 2 = 12/SU so SU = 6, or y = 6.
Note: This is generealized by the Power of a Point, which states that if you have two chords that intersect, then you can do the same thing and it will show that QU*SU=RU*TU. (You can change the variables but the similar triangles stay the same).
Answer:
Step-by-step explanation:
Given
Solving (a): n
To solve for n;
We make use of
Substitute values for XY and XZ
Divide through by -6
Solving (b) XY
Substitute 3 for n
Solving (c): XZ
Answer:
8x and -20y
Step-by-step explanation:
any number that contains a variable is a coefficient.
Answer:
It's false, this number is a rational number.
Step-by-step explanation:
It's false, the kind of decimal where the same digits repeats forever are known as periodic decimals and they can be represented with fractions therefore they are a part of the rational numbers. To represent this number in a fraction form we need to first identify the part that repeats, in this case it's 7, since it's only one number we can insert it in the numerator and the denominator will have a 9, if it were two numbers the denominator would have a 99 and so on. So in this case:
7/9 = 0.7777...
Could you post the equation? I’d be happy to help!
