Answer:
what is the question?
Step-by-step explanation:
Answer:
x = -5
Step-by-step explanation:
3+X=-2
Subtract 3 from each side
3-3+X=-2-3
x = -5
Answer:
D
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.
Answer:
5r^2+2
Step-by-step explanation:
(4r^2 – 3r + 2) – (-r^2 – 3r) =
Distribute the minus sign
(4r^2 – 3r + 2) +r^2 + 3r =
Combine like terms
(4r^2 + r^2 – 3r+ 3r + 2) =
5r^2+2
Answer:
Step-by-step explanation:
We know that the diameter of the fountain is 3 feet and that it is in the center of the pond.
We know that the area of a circumference is:
where r is the radius of the circumference.
further
d = 2r
Where d is the diameter of the circumference.
Then the radius 
of the source is 1.5 ft.
The radius 
of the pond is 1.5 + 3 = 4.5 ft
Finally the area of the pond is equal to the area of the ring that is shown in the image
