The length of the bigger piece is 17 meters and the entire length is 29 meters
Answer:
n =-19
Step-by-step explanation:
3* (n+7) = -36
Distribute
3n+21 = -36
Subtract 21 from each side
3n+21-21 = -36-21
3n = -57
Divide by 3
3n/3 = -57/3
n =-19
(x,y)
(3,-12)
(6,k)
y=mx+b
sloope=m
y=-2x+b
sub known point
(x,y)
(3,-12)
x=3
y=-12
-12=-2(3)+b
-12=-6+b
-6=b
y=-2x-6
(6,k)
k=-2(6)-6
k=-12-6
k=-18
k=-18
Find the domain and range of the real-valued function f(x) = x2 + 7. B) The domain is all real numbers x such that x ≥ 0 and the range is all real numbers f(x) such that f(x) ≥ 7. C) The domain is all real numbers x such that x ≥ 0 and the range is all real numbers.
I think it may be 3. not sure though
