Easy,
23y-(7x-2y)+x
<span>There is an imaginary</span> 1 in front of the parentheses, making it,
23y-1(7x-2y)+x
Now, distribute the 1.
-1*7x= -7x
and
-1*-2y= 2y
Leaving your problem looking like...
23y-7x+2y+x
Combine your apples and oranges.....
25y-6x
Thus, your answer.
3X-1/4=2
3X=2+1/4
3X=9/4
X=3/4
Vertical angles equal eachother
set angle 4 and angle 8 equal to eachother
3x=x+40
-x both sides
2x=40
÷2 both sides
x=20
solve for angle 4
3 (20)
60 B
16y=6x+42
16/16y=6x/16+42/16
y= 3x/8 + 21/8
Answer:
Step-by-step explanation:
The standard form of a circle's equation is
where h and k are the circle's center and r is the radius. We are told, and we can see, that the center of the circle is (0, 0) so h = 0 and k = 0. The radius, given as 4, goes into the equation squared, so the equation is
which simplifies down to
, choice C.
