A reflection over diagonal RT
1) Considering that we're dealing with reflection symmetry and the Parallelogram QRST.
(In red the axis of symmetry)
2) So we can reflect that quadrilateral QRST onto itself by those two red lines of symmetry, its line half of that figure is mirrored across.
3) Hence, examining the answers, we can state that the answer is

Since it takes 3 minutes to warm up, and then 6 minutes to make a coffee, we can apply the following relationship:
[tex]M(c)=6+3c[/tex]Where c represents the number of coffees.
Plugging in 12 cups into the equation:
M(c) = 6 + 3*12 = 42
-It will take 42 minutes to make 12 cups of coffee.
In 45 minutes, we can get the amount of cups of coffee obtained by plugging the value into the equation:
[tex]45=6+3\cdot c[/tex]Isolating the value of c:
[tex]\frac{45-6}{3}=c[/tex]Subtracting numbers:
[tex]13=c[/tex]-He can make 13 cups of coffee in 45 minutes.

ANSWER:
not a solution
STEP-BY-STEP EXPLANATION:
We have the following system of equations:
[tex]\begin{gathered} 2x+5y=-18 \\ 6x-4y=15 \end{gathered}[/tex]We have the point (1, -4), which we can interpret like this:
x = 1
y = -4
We replace these values and if it meets the system of equations, if it is a solution and if not, it is not a solution.
Therefore:
[tex]\begin{gathered} 2\cdot1+5\cdot-4=-18 \\ 2-20=-18 \\ -18=-18 \\ \\ 6\cdot1-4\cdot-4=15 \\ 6+16=15 \\ 22=15 \end{gathered}[/tex]The first equation does, but the second does not, which means that the point (1, -4) is not a solution of the system of equations

A ladder leans against a building, making a 46 degree, angle of elevation with the ground.
The top of the ladder reaches a point on the building that is 21 feet above the ground.
To find: The distance, x between the base of the building and the base of the ladder.
Explanation:
It is given that,
The height of the building is 21 feet.
The angle of elevation is 46 degrees.
Therefore,
[tex]\begin{gathered} \tan46=\frac{21}{x} \\ x=\frac{21}{\tan46} \\ x=\frac{21}{1.0355} \\ x=20.27946 \\ x=20.3ft \end{gathered}[/tex]Hence, the value of x is 20.3ft.

0.714
Explanation:
5/7 = 0.7143 (4 decimal place)
To round to the nearest thousandth, we count the numbers after the point and stop at the 3rd number. Then we round the number after it (fourth number) and add to the 3rd number.
If the fourth number is 5 0r more, we round to 1. If less than 5, we round to zero
In this case, the fourth number after the decimal point is 3. Since it is less than 5, we round to zero.
5/7 to the nearest thousandth = 0.714
