The equation of a circle with center (h,k) and radius r is
(x-h)²+(y-k)²=r²
so
given center is (3,-4)
(x-3)²+(y-(-4))²=r²
(x-3)²+(y+4)²=r²
find r² by subsitutiong the point taht it passes through which is (6,5)
so
(6-3)²+(5+4)²=r²
3²+9²=r²
9+81=r²
90=r²
so
(x-3)²+(y+4)²=90 is da equation
4th equation
Remember that that the further the the left a digit is, the bigger the number, for example 0.8 is bigger than 0.08 which is in turn bigger than 0.008
Using this we can see that;
0.9, 0.71
Are the only two numbers bigger than 0.7
Answer:
(x+7) (5x+3)
Step-by-step explanation:
that's what I got
Answer:
Plug in 1ft/12in
This will give you 36 ft
Step-by-step explanation:
After plugging in, multiply across and simplify/divide and you get your answer
For
|a|<b
assume
-b<a<b
for
|a|=b
assume
a=b and a=-b
|y+4|<1
-1<y+4<1
minus 4
-5<y<-3
A
|2t|-5=7
add 5
|2t|=12
assume
2t=12
2t=-12
divide by 2
t=6
t=-6
B is answer
|a|-3/4=-5/8
|a|-6/8=-5/8
add 6/8 to oths ides
|a|=1/8
a=1/8 and a=-1/8
A
BBA is the order ofo answers
