because the x values are identical the radius would be found by subtracting the y values.
6-2 = 4
the radius is 4
The answer is the first tile on the very left
s = sqrt(227) where "sqrt" is shorthand for "square root"
To get this answer, we basically replace A with 227 and we go from
A = s^2
to
227 = s^2
So if s^2 = 227, then s = sqrt(227) after we apply the square root to both sides. Because s is some length value, it makes no sense to have it negative. Therefore we don't consider the negative version of the square root.
Question:
Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.
Select all that apply.


(3.6,0.6)
(-2.6,0.4)
(-3.6,0.6)
(2.6,0.4)
(4.5,-1.5)
Answer:
Option A :
is the solution to the system of equations.
Option D:
is the solution to the system of equations.
Explanation:
The two equations are
and 
To determine the solution of the system of equations using technology, let us plot the equations in the graphing calculator.
The solution of the system of equations is the intersection of the two lines.
Thus, from the graph, we can see that the two lines f(x) and g(x) intersect at the points
and 
Rounding off the solution to the nearest tenth, we get,
and 
Thus, the solution to the system of equations is
and 
Hence, Option A and Option D are the correct answers.
Answer:
Therefore, Sara’s current age (5 years later) is 19 years old.
Step-by-step explanation:
Let xx be Sara’s age five years ago. Therefore, Sara’s aunt’s age 5 years ago is 4x4x.
The difference in their ages is a constant, no matter how many years have gone by. (Can you see why?)
4x−x=42
3x=42
x=42/3
x=14
14+5=19
Therefore, Sara’s current age (5 years later) is 19 years old.
