The answer is 14. The two lower angles are 50 each 100 total and so the top angle must equal 80. If you set it equal to 80 you get 14.
X + y = 10
x - y = 2
add the equations together
2x = 12
x = 6
6 + y = 10
y = 3
Answer: x = - 8
Step-by-step explanation:
= 8
cross multiplying , we have
8 ( 7 + x) = x
Expanding the Left Hand Side of the equation , we have :
56 + 8x = x collecting the like terms , we have
56 = x - 8x
56 = -7x
dividing through by - 7 we have :
- 8 = x
Therefore :
x = -8
Answer: y=1/4 x - 7
Found the equation using slope-intercept form
Answer:
Even
Step-by-step explanation:
If you switch every x in the function for a -x it is still the same result for every value of x you plot. Plus you have an image symmetry for ever function to an even power and for cosine function as well.
