Answer:
vertical angles?
Step-by-step explanation:
Answer:
169/8
Step-by-step explanation:
9 7/8 = 79 / 8
11 2/8 = 90 / 8
90/8 + 79/8
The denominator (8) stays the same
90+79 = 169
169/8 or 21 1/8
Answer:
T(a) =(a+2)/11
Step-by-step explanation:
The inverse of the inverse is the function
To find the inverse let T^-1(a) be y
y = 11a -2
Exchange y and a
a = 11y -2
Solve for y
Add 2 to each side
a+2 = 11y -2 +2
a+2 =11y
Divide each side by 11
(a+2)/11 =y
T(a) =(a+2)/11
I'm not sure what the answer is but I'll add subtract and multiply something. Remember PEMDAS for the order of operations
10 x 2 - 5
= 20 - 5
= 15
That's an example
