The solution region for the given pair of inequalities is found to be the common shaded region in the graph attached.
For drawing the graph of any inequality, we first have to assume the inequality as an equation and draw the graph of the resulting equation. Hence, finding the points for the inequality , we let the inequality as:
Putting y=0, we get:
The point will be: (-2,0)
Now, putting x=0, we get:
The point will be: (0,4)
Now as the sign of inequality is >, the line of graph will be dotted.
Taking a test point (0,0) to find the shaded region, substituting this in the inequality,
So, the shaded region will be away from the test point.
Similarly, finding the points for the inequality , we let the inequality as:
Putting y=0, we get:
The point will be: (6,0)
Now, putting x=0, we get:
The point will be: (0,6)
Now, as the sign of inequality is of , the line of graph will be solid.
Taking a test point (0,0) to find the shaded region, substituting this in the inequality,
So, the shaded region will be towards the test point.
The resulting graph is attached after the solution.
The solution to the pair of given inequalities will be the shaded region that is common between both the individual inequality's shaded regions.

The volume of a rectangular prism if the length is 10ft is 250ft2.
What is a prism?A transparent optical prism is a device intended to refract light and has flat, polished surfaces. Prisms do not have two parallel surfaces; at least one of their surfaces must be slanted. Since a triangular prism with a triangular base and rectangular sides is the traditional geometrical shape of an optical prism, this type is typically meant when the word "prism" is used in everyday speech. Certain optical prism varieties don't actually have geometric prism shapes. Any material that transmits the wavelengths for which it is intended can be used to create prisms. Glass, acrylic, and fluorite are common building blocks.
From description, l = 2h = 2w
Since it has a square base,w=h
V = lwh = 2w•w•w = 2w3
Surface area, A = 2(wl+hl+hw) = 2(2w2+2w2+w2) = 250
5w2=250/2 = 125
w2= 25
V= 2(5)3 = 2(125)= 250 ft2

Answers
Answer:
Mean = 260.45
Median = 284
Mode = 287, 285 (there are 2 modes)
Since it is a championship sports team , it is likely that this data is representative of all players in that league
Step-by-step explanation:
Mean = Sum of the weights/11 = 2865/11 = 260.45
Median is the middle of the data set when the data values are arranged in ascending order
In ascending order: 206, 216, 217, 235, 273, 284, 285, 285, 287, 287, 290
Mode is the value that occurs the maximum number of times in a data set

A cyclist rides around a flat, circular track at constant speed. is the cyclist's acceleration vector zero?
Answers
The cyclist's acceleration vector is not zero.
For given question,
A cyclist goes around a level, circular track at constant speed.
We know that , acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
When cyclist move around a circular track with constant speed cyclist's direction of motion changes with time.
This means, cyclist's velocity will change means cyclist's will have acceleration.
And cyclist's acceleration will not be zero.
Therefore, the cyclist's acceleration vector is not zero.

A soup recipe requires 6 ounces of bouillon plus 2 ounces for each quart of water used.
This relationship is represented by the equation b = 2q +6, where b represents the
number of ounces of bouillon and q represents the number of quarts of water
Answers
Answer:
Slope=1.000/2.000=0.500
b-i
q-i
b-(2*q+6)=0
Step-by-step explanation:
1.1 Solve b-2q-6 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line b-2q-6 = 0 and calculate its properties
Notice that when b = 0 the value of q is 3/-1 so this line "cuts" the q axis at q=-3.00000
q-intercept = 6/-2 = 3/-1 = -3.00000
When q = 0 the value of b is 6/1 Our line therefore "cuts" the b axis at b= 6.00000
b-intercept = 6/1 = 6.00000
Slope is defined as the change in q divided by the change in b. We note that for b=0, the value of q is -3.000 and for b=2.000, the value of q is -2.000. So, for a change of 2.000 in b (The change in b is sometimes referred to as "RUN") we get a change of -2.000 - (-3.000) = 1.000 in q. (The change in q is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 1.000/2.000 = 0.500
Slope = 1.000/2.000 = 0.500
b-intercept = 6/1 = 6.00000
q-intercept = 6/-2 = 3/-1 = -3.00000

Arithmetic sequencet5 = 8t10 = 15.5First term = aCommon difference = da + 4d = 8
a + 9d = 15.5
Subtract to eliminate a9d - 4d = 15.5 - 8
5d = 7.5
d = 7.5/5
d = 1.5

a + 6 = 8
a = 8 - 6
a = 2

Equation, which is defined as the quality of being equal, is frequently represented by a mathematical expression with equal values on either side or by a situation in which numerous factors must be taken into account.
Consider the equation,
x² + 20 = 4
Subtracting 20 from each side of the equation.
x² + 20 - 20 = 4 - 20
x² = - 16
√x² = √ - 16
