Elie was left with $16 at the end of the trip
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 Elie who took $200 to spend during summer vacation. She spent $32 a day for 5 days. Then she bought gelato for her and three friends for $6 each.
Assume that she is left with $[x]. Then, we can write the equation as -
x = 200 - {(32 x 5) + (6 x 4)}
x = 200 - {160 + 24}
x = 200 - 184
x = 16
Therefore, Elie was left with $16 at the end of the trip.

Find the slope of line 2, which is parallel to line 1. Line i goes through the points
(-13, -6), (7, 15).
(-13, -6), (7, 15) = 1.05
Equation: y = 1.05x + 7.65.
The entered points belong to an increasing, linear function.
Answer:
m = rise / run = 21/20, or m = 1.05
Step-by-step explanation:
If the lines are parallel, their slopes are identical. So we can find the slope of line 1 and know that it's also the slope of line 2.
From (-13, -6) to (7, 15), the x-component increases by 20 units from -13 to 7. Thus, the "run" in m = rise / run is 20. Likewise, the "rise" is 21.
Thus the slope in question is m = rise / run = 21/20

Simplify the expression.
Step-by-step explanation:
since all base numbers have the same exponent, we can combine the base numbers first and then apply the exponent :
(12×45×50)^(1/3) = 27000^(1/3)
and remember what a 1/... exponent means : it means the root of the ... degree.
so, here we need a cubic root or a root of the third degree

domain: {x | x is a real number}; range: {y | y > 2}
domain: {x | x is a real number}; range: {y | y > –2}
The domain and range of the function is domain: {x | x is a real number}; range: {y | y > 2}
Given the exponential function expressed as;
[tex]f(x)=(\frac{1}{6})^x + 2[/tex]
The domain of the function will be the input value "x" for which it exists. For the function given, it exists for any value of "x".
Hence the domain of the function exists on all real numbers. Hence the domain in set notation is domain: {x | x is a real number}The range of the function will be the output value "f(x)" for which it exists. For the function given, it exists for any value of f(x) greater than 2.Hence the range of the function exists on any value of f(x) greater than 2.

The error is in labelling the triangles.
What are triangles?A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.
Given are two ABC and RST
Since, Δ ABC ≅ Δ RST
That gives,
AB = RS
BC = TS
CA = RT
In figure,
AC has been equated to RS, which is wrong or incorrect because the corresponding side of AC is RT
The correct labelling will be
AB = RS = 5
BC = TS = 5
CA = RT = 5.5
Hence, The error is in labelling the triangles.
