Answer:
Point form: (-1,1)
Step-by-step explanation:
y=2x+3, -y=2x+1
Point form: (-1,1)
Equation form: x = -1, y = 1
Answer:
A = 981.3 ft^2
Step-by-step explanation:
Here we're calculating the area of a semicircle of radius 25 ft.
The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.
Here pi = 3.14 and r = 25 ft, and so the area/space in question is
A = (1/2)(3.14)(25)^2
A = 981.3 ft^2

Answer:
B. 3(a + 7) + 3/(a + 2)
Step-by-step explanation:
Just substitute (a+2) in for every (x) in the equation:
f(a + 2) = 3 ((a + 2) + 5) + 4/(a+2)
= 3 (a + 7) + 4/(a+2)
Answer:
Let,
P= kT
P = 10, when T = 500
So, 10=k500
or, k=10/500
or, k=1/50
When T=509
P=kT
or, P=(1/50)×509
or, P=508/50
or, P = 10.18
And when P = 509 (since the question isn't clear)
509=(1/50)×T
or, T=509×50
or, T=25450
