Answer:
D x2 + y2 = 4
Step-by-step explanation:
The following are the functions
y = 4
y = x - 4
y = x^2 - 4
but
x^2 + y^2 = 4 is not a function as there should be minimum one x value with two or more y values
But the above equation does not meet the criteria so this represent non-function
I think the answer is 9 i might be wrong
Answer: -587
Step-by-step explanation:
DO you have a real question???
1.Since 5 is less than 8, borrow 1 from the next column to make 15.
2.Calculate 15 - 8, which is 7.
3.Calculate 3 - 3, which is 0.
4.Since 2 is less than 5, borrow 1 from the next column to make 12.
5.Calculate 12 - 5, which is 7.
6..<span>Calculate 9 - 2, which is 7.</span>
7.<span>Therefore, 102.45 - 25.38 = 77.07.</span>
In the figure you can say ∠1 + ∠4 = 180° because both together make a line so you can say : 63° + ∠4 = 180° ⇒ ∠4 = 180° - 63 ° = 117 ° so the answer is :
∠4 = 117° :)))
i hope this is helpful
have a nice day
