Answer:
Step-by-step explanation:
The axes of symmetry are shown and labeled m and n. Reflection across either (or both) axis of symmetry will map the figure to itself. Apparently, you want to designate those reflections as ...
Ra . . . where a = m
Rb . . . where b = n
The answer is x = 34/19, y = 27/19
3y + 6x = 15
9y - x = 11
_____
Multiply the second eqution by 6:
3y + 6x = 15
54y - 6x = 66
_____
Sum up two equations:
3y + 54y = 15 + 66
57y = 81
y = 81/57
y = (81 : 3)/(57 : 3)
y = 27/19
Use the second equation to calculate x:
<span>9y - x = 11
</span>x = 9y - 11
x = 9 * 27/19 - 11
x = 243/19 - 11 * 19/19
x = 243/19 - 209/19
x = (243 - 209)/19
x = 34/19
Answer:
52 in^2
Step-by-step explanation:
Answer:
12/13
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin B = 12/13
Answer:
The additive inverse of a number is what you add to a number to create the sum of zero. So in other words, the additive inverse of x is another number, y, as long as the sum of x + y equals zero. The additive inverse of x is equal and opposite in sign to it (so, y = -x or vice versa).
