Answer: 5, 72
Step-by-step explanation:
Given the following questions :.
The value of 3 minus (negative 2)
3 - (-2) = 3 + 2 = 5
A number line going from Negative 5 to positive 5, what is the product of 6(negative 12)
6 × (-12) = - 72
Answer:
The answer to your question is: y = 1/4x - 5
Step-by-step explanation:
Data
slope = m = 1/4
Point (0, - 5)
Formula
(y - y1) = m(x - x1)
Substitution
(y + 5) = 1/4 ( x - 0)
Simplification
(y + 5) = 1/4 (x)
y = 1/4x - 5 Result
Answer:
Move all terms to the left side of the equation and simplify.
3x²−12x−21=0
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=3, b=−12, and c=−21 into the quadratic formula and solve for x.
(12±√(−12)²−4⋅(3⋅−21)0/2⋅3 Simplify => x=2±√11
The result can be shown in multiple forms.
Exact Form: x=2±√11
Decimal Form: x=5.31662479…,−1.31662479…

Answer: 2
Explanation: Quartile 1 is 2, and Quartile 2 is 4, and 4-2=2.
Answer:
![49\pi \approx 153.94\text{ m}^2](https://tex.z-dn.net/?f=49%5Cpi%20%5Capprox%20153.94%5Ctext%7B%20m%7D%5E2)
Step-by-step explanation:
The area of a circle is pi multiplied by the radius squared:
.
The figure shows a diamater equal to 14 m, so the radius is half of that, 7 m.
![A=\pi(7)^2=49\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%287%29%5E2%3D49%5Cpi)
A calculator gives a decimal approximation of 153.94 meters squared. (![\pi\approx3.1415927](https://tex.z-dn.net/?f=%5Cpi%5Capprox3.1415927)
