m = 7.50 + 12.50
m - 7.50 = 12.50
Explanation:Cost of the book = $7.50
Amount remaining on the gift card = $12.50
m = Amount on the gift card in dollars when Salim received it
Amount on the gift card in dollars when Salim received it = Cost of the book + Amount remaining on the gift card
m = $7.50 + $12.50
m = 7.50 + 12.50
Another form of the equation:
subtract 7.5 from both sides:
m - 7.50 = 7.50 - 7.50 + 12.50
m - 7.50 = 12.50
Hence, equation that can be used to solve m:
m = 7.50 + 12.50
m - 7.50 = 12.50

10x 10 0 y Match the function with the graph 1 b
Answers
To answer this kind of questions, we need to take attention to the original function. In this case, the function is y = 1/x.
We can see from the graph that this function if we multiply this function by -1, the function takes the form of the graph. But we need to add to this function two units in the y-axis direction to obtain the function represented in the graph.
Therefore, the function that matches the one in the graph is y = -1/x +2 (option a).

we know that
x+y =14,593 --------> x=14,593-y -----> equation 1

x=y+443 ------> equation 2
Solve the system of equations
Equate both equations

First we need to define what collinear and coplaner means.
It is said that 3 or more points are collinear if they all lie on the same line.
From the diagram, point R, S, T do not lie on the same line.
Hence point R, S and T are not collinear
For a point or line to be coplaner, it must line in the same plane
Also looking at the diagram, points R, S, T do not lie in the same plane.

If CE and FH are parallel lines and angle EDG is 42 degree, then angle CDB is also 42 degree
If CE and FH are parallel lines and the line BI is the transversal
angle EDG = angle DGF (interior alternate angles)
(when two lines are parallel and is cut by a transversal, the interior alternate angles are equal)
So. angle DGF = 42 degree
angle CDB = angle DGF (corresponding angles)
(when two lines are parallel and is cut by a transversal, the corresponding angles are equal)
angle CDB = 42 degree
Therefore, if CE and FH are parallel lines and angle EDG is 42 degree, then angle CDB is also 42 degree

Answers
Data
• $4.55 per hour
,• Earns an average of 19 tips (assuming that the tips are in dollars).
Procedure
To identify the algebraic expression, we have to identify the variable earn (the quantity that depends on something) and the fixed (the one that is mostly constant).
Based on the information given, we can assume that the variable quantity is $4.55, as it depends on the time, and the fixed is $19. Thus, the algebraic expression can be written as follows:
[tex]E=4.55t+19[/tex]where E represents the earnings and t represents the time.

Is it possible for a standard deviation to be equal to zero ?
Answers
Given:
The objective is to explain whether it is possible for a standard deviation to be equal to zero.
Explanation:
A standard deviation can be zero when all the data are equal.
In general the value of standard deviation will decrease while approaching close to the mean value. Similarly, the standard deviation will increase if data points are away from the mean value.
Hence, standard deviation can be zero if all the obtained/provided data contains equal value.
