Answer:
5x+17
Step-by-step explanation:
Answer:
32/5
Step-by-step explanation:
1)Write the equation again, but replace ___ with x:
(2y + 4b) + 5 = x + (4b + 5)
2) Eliminate parenthesizes (if there is "-" in front of them, change the sign in front of everything that is inside them; if there is "+" just leave it the same):
2y + 4b + 5 = x + 4b + 5
3) Transfer 4b + 5 from the left side to the right by changing signs into the opposite ones:
2y = x + 4b + 5 - 4b - 5
2y = x
So, the answer will be 2y. Hope this helps!
Answer:
No No Yes
Step-by-step explanation:
The a-values are repeated, with different b-values in the first and second tables, so b isn't a function of a.
The general equation of the circle is:
(x -xo)^2 + (y - yo)^2 = r^2
Where xo,yo are the coordinates of the center and r is the radius of the circle.
Here (xo,yo) is (-16,30) and you can find the radius.
You can find the radius using the equation of the distance (Pythagoras) between the center (-16,30) and any point on the circunference. Here use (0,0)
r^2 = (-16 - 0)^2 + (30 - 0)^2 = 1156
Then, the equation is>
(x - (-16) )^2 + (y - 30)^2 = 1156
=> (x + 16)^2 + (y - 30)^2 = 1156. <----- answer
