Answer:
option d is the correct answer
Answer:
The correct answer is (-3,-7). This is because you can plug it in and the two sides are equal to each other. When you plug -3 in for x, you subtract for from it and get -7 since the y term is -7 the answer is -7=-7, thus (-3, -7) is the answer.

Answer:
4 and 13
Step-by-step explanation:
You want integer solutions to ...
15 ≤ n(n+1) ≤ 200
If we let the limits be represented by "a", then the equality is represented by ...
n² +n -a = 0
(n² +n +1/4) -a -1/4 = 0
(n +1/2)^2 = (a +1/4)
n = -1/2 + √(a +1/4)
For a=15, we have
n ≥ -1/2 + √15.25 ≈ 3.4 . . . . . minimum n is 4
For a=200, we have
n ≤ -1/2 + √200.25 ≈ 13.7 . . . maximum n is 13
The least and greatest integers on the cards are 4 and 13.
Answer:
<em>Diameter= 11.27 feet</em>
Step-by-step explanation:
<em>Circle = 2πr</em>
<em>or, 11.27π = 2πr</em>
<em>or, 11.27π/2π = r</em>
<em>r = 5.635 ft</em>
<em>diameter = 2r</em>
<em>= 2 x 5.635</em>
<em>= 11.27 feet</em>
Probably brand A because it weights the least amount so then you can get more shingles in one lift since it needs to be at the most 650 pounds per lift.
