Answer:
center: (-10,-4)
radius: 9
Step-by-step explanation:
Let's start off by moving the 35 to the other side and grouping the x and y terms we have
(x²+20x)+(y²+8y)= -35
Next we take the term with the x coeficcent, divide it by 2, and square it
so
for the x we would do (20/2)²=100
and make sure we add that to the 35
(x²+20x+100)+(y²+8y+16)= -35+100+16
next factor everythign to get
(x+10)²+(y+4)²=81
therefore the center is (-10,-4)
and the radius is √81 or 9
5(2)>3(1)+4
10 > 7. Is True because 10 is greather than 7. All needed to do is evaluate the x and y variables for each possibility. A, B, C D. And see if is a logical answer.
Any other combination gives you a false statement.
Answer:
it translated down 6 and right 6
Step-by-step explanation:
I don't really know what notation you wanna use, but yeah. thems the facts
In standard form the answer will be if you go by (Ax+by=c )then I must say it's 3x-7y=9
Answer:
y = 1x - 3
Step-by-step explanation:
Note that the given line has slope +1.
Any line parallel to this line must also have slope +1.
Apply the slope-intercept form y = mx + b:
Inserting -3 for y, 0 for x and 1 for m, we get the y-intercept
-3 = 1(0) + b, which tells us that b = -3 and that the desired equation is
y = 1x - 3
