Determine Whether an Ordered Pair is a Solution of a System of Linear Inequalities
The definition of a system of linear inequalities is very similar to the definition of a system of linear equations.
System of Linear Inequalities
Two or more linear inequalities grouped together form a system of linear inequalities.
A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown below.
\left\{\begin{array}{c}x+4y\ge 10\hfill \\ 3x-2y<12\hfill \end{array}
To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities. We solve the system by using the graphs of each inequality and show the solution as a graph. We will find the region on the plane that contains all ordered pairs \left(x,y\right) that make both inequalities true.
Solutions of a System of Linear Inequalities
Solutions of a system of linear inequalities are the values of the variables that make all the inequalities true.
The solution of a system of linear inequalities is shown as a shaded region in the x-y coordinate system that includes all the points whose ordered pairs make the inequalities true.
To determine if an ordered pair is a solution to a system of two inequalities, we substitute the values of the variables into each inequality. If the ordered pair makes both inequalities true, it is a solution to the system. s

Parveen buys 3 small bags of peanuts she gives the shopkeeper £2 and gets 80p change what is the cost of one pag of peanuts?
Answer:
$0.4
Step-by-step explanation:
Let cost per bag = x
Number of bags purchased = 3
Amount given to shopkeeper = $2
Change gotten = $0.80
(Cost per bag * number of bags purchased) + change obtained = amount given to shopkeeper
(x * 3) + 0.80 = 2
3x + 0.80 = 2
3x = 2 - 0.80
3x = 1.20
x = 1.20 / 3
x = 0.4
$0.4
If you roll a single six-sided die, what is the probability of rolling an odd number?
I am not sure but the probability could be 50% because there are 3 odd numbers on a die out of 6 and so half would be 50/100. Or 3/6.

The formula for the volume of a rectangular prism is V=l×w×h. Multiply the length times the width times the height to write a simplified expression in standard form to represent the volume of the box.
Answer:
Volume of box= Box Area * Box height
Step-by-step explanation:
If the box has equal sides then the l=w=h length is equal to height and both are equal to width so this can also be written as l=l=l or
Volume= length * width * height
V= l*w*h
V= l*l*l
V= l³
or if the three sides are not equal this can also be written as
Volume of box= Box length * Box width * Box height
If we observe closely we find that length * breadth gives the area so the volume of the box can also be written as
Volume of box= Box length * Box width * Box height
Volume of box= Box Area * Box height

Answer:
B. 254.3
Step-by-step explanation:
The formula for the area of a circle is:
[tex]A = \pi\cdot r^2[/tex]
and r is half the diameter.
[tex]r = 18in / 2 = 9in\\~\\A = \pi \cdot (9in)^2 \approx 3.14 \cdot 81in^2 = 254.34in^2[/tex]
Answer:
D. 254.3
Step-by-step explanation:
Use the formula pi times the radius squared to get the area.
The radius is nine because the diameter of the diagram is 18. (The radius is always half the diameter).

Answer:
7 7/15
Step-by-step explanation:
Which function produces an output of 5 for an input of -6?
A.f(x) = x + 1
B.f(x) = 2x + 4
C.f(x) = x - (-1)
D.f(x) = -x - 1
Answer:
The answer is D
Step-by-step explanation:
Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

The area of the surface of a pool table is 24 square feet. The pool table is 6 feet long. How wide is it?
No procedure
Answer: The pool table is rectangle, so we assume it with Length a feet and b feet, respectively.
So area=a*b=24 square feet
perimeter=2(a+b)= 22 feet
then we calculate with this two equation to get a and b.
because a+b=11, then a=11-b, we put this into a * b=24
then we get (11-b)*b=24,
b^2-11b+24=0
b=3 feet or b=8 feet
then we can get a by a=11-b, if b=3, then a=8; if b=8, then a=3.
so the dimension of the pool table is 3 feet and 8 feet
