Yes, (3,-1) is a solution to the graphed system of inequalities.
What are system of inequalities?When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.
A collection of inequalities for which we consider a common solution for all inequalities is called a system of inequalities.
As we can see in the graph that the two lines are interest in the second quadrant at point such as(x, -y).
So, the point will be a solution also because it lies in the shaded region.
Therefore, Yes, (3,-1) is a solution to the graphed system of inequalities.

Given:
A kitchen shop sells bowls in sizes small, medium and large.Draw a Venn diagram with 3 intersecting circles. Label each circle:
S = small bowlsM = medium bowlsL = large bowls----------------------------------------------------------------------------------------------
Given:
5 people bought all three sizes of bowl.Enter "5" in the central overlapping section of the Venn diagram.
----------------------------------------------------------------------------------------------
Given:
7 people bought a small bowl and a large bowl.We know that 5 people bought all 3 bowls, so to find the number who bought a small and large bowl (but not a medium bowl):
⇒ 7 - 5 = 2
Enter "2" in the section S and L but not M.
----------------------------------------------------------------------------------------------
Given:
In total, 27 people bought a small bowl, of which 12 also bought a medium bowl.First, calculate the number of people who bought only a small and medium bowl (but not a large bowl). We know that 5 people bought all 3 bowls, so subtract 5 from 12.
Enter "7" in the section S and M but not L
A total of 27 people bought a small bowl, so to find the number who bought a small bowl only (not a medium and/or large bowl), subtract the other found numbers from 27:
⇒ 27 - 5 - 2- 7 = 13
Enter "13" in the S only section.
----------------------------------------------------------------------------------------------
Given:
In total, 66 people bought a medium bowl, of which 15 also bought a large bowl.First, calculate the number of people who bought only a large and medium bowl (but not a small bowl). We know that 5 people bought all 3 bowls, so subtract 5 from 15.
Enter "10" in the section M and L but not S
A total of 66 people bought a medium bowl, so to find the number who bought a medium bowl only, subtract the other found numbers:
⇒ 66 - 5 - 7 - 10 = 44
Enter "44" in the M only section.
----------------------------------------------------------------------------------------------
Given:
On a given day, 100 people each bought at least one bowl from the shop.To find "L only" subtract all the known numbers from 100:
⇒ 100 - 5 - 2 - 7 - 13 - 10 - 44 = 19
Enter "19" into the L only section.
----------------------------------------------------------------------------------------------
Finally, to work out the total number of people that bought a large bowl, add up the numbers in the L circle:
⇒ 2 + 5 + 10 + 19 = 36

Answers
The expression 0.3d = 0.95 could be used to find the number of dimes he has.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have joe who has dime and nickels in his piggy bank totaling $1.45 the number of nickels. He has is 5 more than twice the number of dimes [d].
We can write the the number of nickels as -
[n] = 2d + 5
0.1d + 0.1(2d + 5) = 1.45
0.1d + 0.2d + 0.5 = 1.45
0.3d = 0.95
Therefore, the expression 0.3d = 0.95 could be used to find the number of dimes he has.

Find TS if RM = 5 and MS = 7 10. Find RT if RM = 1/2 and MS = 1/4 thank you so much if you can help me!!
Answers
We can make a drawing to see better:
7) We know that RM = 4 and MS = 9, so:
\(\begin{gathered} \tan a=\frac{MS}{RM}=\frac{TM}{MS} \\ TM=\frac{MS^2}{RM}=\frac{9^2}{4}=\frac{81}{4}=20.25 \end{gathered}\)The answer is TM = 20.25
8) We know that RS = 20 and RM = 8, so:
\(\begin{gathered} \sin b=\frac{RM}{RS}=\frac{RS}{RT} \\ RT=\frac{RS^2}{RM}=\frac{20^2}{8}=\frac{400}{8}=50 \end{gathered}\)The answer is RT = 50.
9) We know that RM = 5 and MS = 7, so:
\(\begin{gathered} \tan b=\frac{RM}{MS}=\frac{RS}{TS} \\ TS=RS\cdot\frac{MS}{RM} \\ RS=\sqrt[]{RM^2+MS^2} \\ TS=\sqrt[]{RM^2+MS^2}\cdot\frac{MS}{RM} \\ TS=\sqrt[]{5^2+7^2}\cdot\frac{7}{5}=\sqrt[]{25+49}\cdot\frac{7}{5} \\ TS=\sqrt[]{74}\cdot\frac{7}{5}\approx12.043 \end{gathered}\)The answer is TS = 12.043
10) We know that RM = 1/2 and MS = 1/4, so:
\(\begin{gathered} \sin b=\frac{RM}{RS}=\frac{RS}{RT} \\ RT=\frac{RS^2}{RM}=\frac{RM^2+MS^2}{RM} \\ RT=\frac{(\frac{1}{2})^2+(\frac{1}{4})^2}{\frac{1}{2}}=2\cdot(\frac{1}{4}+\frac{1}{16}) \\ RT=2\cdot\frac{4+1}{16}=\frac{5}{8}=0.625 \end{gathered}\)The answer is RT = 5/8 = 0.625

Answers
The equation of a circle centered at the origin with a radius of 12, which is x² + y² = 144.
To find the equation of the circle, we use the standard form of the equation of a circle, which is:
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the center of the circle, and r is the radius.
In our problem, the center of the circle is at the origin, which means h = 0 and k = 0. The radius is given as 12, so we have r = 12. Substituting these values into the standard form equation, we get:
(x - 0)² + (y - 0)² = 12²
Simplifying, we get:
x² + y² = 144
Therefore, the equation of the circle centered at the origin with a radius of 12 is x² + y² = 144.

Prove for all real numbers x and y, if
\(x − ⎣x⎦ ≥ y − ⎣y⎦ then ⎣x − y⎦ = ⎣x⎦ − ⎣y⎦.\)
Given :
\(x − ⎣x⎦ ≥ y − ⎣y⎦\)
To Prove :
⎣x − y⎦ = ⎣x⎦ − ⎣y⎦.
Proof :
Let\(A = ⎣x⎦, B = ⎣y⎦, C = ⎣x − y⎦.\)
Since A ≤ x < A + 1,
we have
A − B ≤ x − y < A + 1 − B
This implies that C = ⎣x − y⎦ lies between A − B and A + 1 − B;
that is, A − B ≤ C ≤ A + 1 − B.
But the only integers that lie between A and A + 1 are A itself and A + 1.
Therefore, either
C = A or C = A − 1 or, equivalently,
\(⎣x − y⎦ = ⎣x⎦ or ⎣x − y⎦ = ⎣x⎦ − 1,\)
but in the second case, we have
⎣x⎦ − ⎣y⎦ > x − y, which contradicts the assumption that
\(x − ⎣x⎦ ≥ y − ⎣y⎦.\)
Hence,\(⎣x − y⎦ = ⎣x⎦ − ⎣y⎦\)
for all real numbers x and y, if
\(x − ⎣x⎦ ≥ y − ⎣y⎦.\)
Therefore, the given statement is proved.

For two acute angles ∠E and ∠F, cos(E)=sin(F). Let m∠E=(8x–12)° and m∠F=(6x–10)°. What is m∠F, in degrees?
Answers
Answer:
If cos(E) = sin(F), then we know that m∠E + m∠F = 90 degrees (since E and F are acute angles).
We are given that m∠E = (8x - 12) degrees, and we want to find m∠F.
We can substitute the given value of m∠E into the equation m∠E + m∠F = 90 degrees, and solve for m∠F:
(8x - 12) + m∠F = 90
m∠F = 78 - 8x
So the measure of angle F is 78 - 8x degrees.
We are also given that m∠F = (6x - 10) degrees. So we can substitute this value into the equation we just found:
m∠F = (6x - 10) = 78 - 8x
We can now solve this equation for x:
6x - 10 = 78 - 8x
14x = 88
x = 6
So we know that x = 6.
Now we can substitute this value back into the equation m∠F = (6x - 10) to find the measure of angle F:
m∠F = (6x - 10) = (6 * 6) - 10 = 24 degrees
So the measure of angle F is 24 degrees.

Answers
A store sold 120 units of good A for $4 each and they sold 340 units of good B for $5 each. The given value of sales was $ 2,180.
To find out the value of sales when a store sold 120 units of good A for $4 each and 340 units of good B for $5 each, we have to calculate the total cost of good A and good B sold respectively and add them together.
Value of sales = Total cost of good A + Total cost of good B Total cost of good A
= Number of units of good A sold x Cost of each unit of good A Total cost of good A
= 120 x $4Total cost of good
A = $480
Total cost of good B = Number of units of good B sold x Cost of each unit of good B Total cost of good
B = 340 x $5
Total cost of good B = $1,700
Therefore,Value of sales = Total cost of good A + Total cost of good B Value of sales = $480 + $1,700
Value of sales = $2,180
Therefore, the value of sales was $2,180.
