You have two equations.
since the second is already isolated, sub in x-4 for every y in equation 1 so that
![x^{2} - 4 [(x-4)^{2}] =16 ](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20-%204%20%5B%28x-4%29%5E%7B2%7D%5D%20%3D16%0A%20)
expand, collect like terms, factor to find x, then plug x value back into original equation to find y
Answer:
x = 4
Step-by-step explanation:
They are vertical angles so they are the same.
10x+60=30x-20
80=20x
4=x
Answer:
It is Can D! :)
Step-by-step explanation:
It just took the quiz! :)
Answer: the statement “measure of <4 is 105 degrees” is incorrect.
Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.
Hope this helps! :)
Answer:
c > -7
Step-by-step explanation:
Isolate the variable c. What you do to one side, you do to the other. Subtract 6 from both sides:
c + 6 (-6) > -1 (-6)
c > -1 - 6
Simplify.
c > (-1 - 6)
c > - 7
c > -7 is your answer.
