What is the average rate of change over the
interval [0.75, 1.125]? Explain the meaning
of the average rate of change.
Answer:
The average rte of change = 6
2) The average rate of change over an interval is the ratio of the total change in the determinate variable or function (values of the output of the function) to the change in the indeterminate variable (values of the input of the function)
Step-by-step explanation:
1) The average of change of the function is found as follows;
At x = 0.75, y = -0.5, at x = 1.125, y = 1.75
Therefore, the average rate of change = (1.75 - (-0.5))/(1.125 - 0.75) = 6
2) The average rate of change over an interval on a graph or of a curve is found by dividing the difference between the y-coordinate values of the two points on the graph by the difference of the x-coordinate values of the two points.

does a ti 83 plus calculator work the same as a ti 84?
Answer:
Yes. Both are graphing calculators. TI 83 has a black only screen while the TI 84 has a colored screen
Yes. The two calculators are the same more or less overall. They have the same functions and features. There are slight differences (eg: the TI84 is slightly faster than the 83 version), but it's not too big a deal since you can do the same math with both versions.
If you can, I recommend using online tools such as Desmos or GeoGebra. These tools are much faster compared to the TI83 and TI84. Also, they allow for multiple colors to be used, so you can tell the graphs apart. There are lots of other features as well (way too many to go over right now), and the best part is that both tools Desmos and GeoGebra are free. Unfortunately, your teacher may not allow you to use them in a test setting. However, I would ask and they may allow a limited version to be used in some capacity.

Answer:
(4.5 , 2.5)
Step-by-step explanation:
The midpoint can be found with the formula
[tex]midpoint = ( \frac{x1 + x2}{2} ).( \frac{y2 + y1}{2} )[/tex]
and (x1 , x2 ) , (x2, y2) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.

Answer:
CM = 16
MD = 16
CD = 32
Step-by-step explanation:
To find the value of x
3x + 1 = 8x - 24 (we know that M is the mid point so both of the lines will be equal)
Transpose
1 + 24 = 8x - 3x
25 = 5x
x = 25/5
x = 5
CM = 3x + 1
= 3(5) + 1
= 15 +1
= 16
MD = 8x - 24
= 8(5) - 24
= 40 - 24
= 16
CD = CM + MD
= 16 + 16
= 32

Point O is on line segment NP. Given NP = 18 and NO = 15, determine the length OP.
Answer:
OP = 3 units
Step-by-step explanation:
Point O is on line segment NP.
Therefore, N - O - P
So,
NO + OP = NP
15 + OP = 18
OP = 18 - 15
OP = 3 units

For which value of x is the figure a rhombus?
A. X=6
B. X= 7.5
C. X=12
D. X=18.75
That is a question about properties of rhombus.
There is a property of a rhombus that says that the its diagonals divided the internal angles in two equals angles.
Now that we know about it, it is easier to solve this question, because now we know that [tex]2x+39[/tex] and [tex]6x - 9[/tex] are equal angles. So, we can make a equation and solve it:
[tex]2x+39 = 6x - 9\\39 + 9 = 6x - 2x\\48 = 4x\\4x = 48\\x=\frac{48}{4} \\x=12[/tex]
Therefore, the value of [tex]x[/tex] is 12. So, the correct alternative is letter C).

3(x - 2) = 16
what is x
Answer:
3(x-2)=16
3x-6=16
3x=16+6
=22
x=22÷3
=22/3
=7/1/3
Solve for x.
-5x = -10
x = 2
x = -2
x = 50
Answer:
Putting x= 2
[tex]( - 5) \times 2 = - 10 \\ - 10 = - 10[/tex]
putting x = -2
[tex]( - 5) \times ( - 2) = - 10 \\ 5 \times 2 = - 10 \\ 10 = - 10 \\ this \: is \: not \: correct \: equation[/tex]
putting x = 50
[tex]( - 5) \times 50 = - 10 \\ - 250 = - 10 \\ this \: is \: also \: not \: correct \: equation[/tex]
so, x = 2 is applicable.

If 8 years are subtracted from the present age of Jessica and 3 is added to the remaining number, then Olivia’s age can be found. If Olivia is two years older than Daniel who is 7 years old, then what is Jessica’s present age?
Answer:
Jessica is 14 years old.
Step-by-step explanation:
Let [tex]o[/tex] equal Olivia's age, let [tex]j[/tex] equal Jessica's age, and let [tex]d[/tex] equal Daniel's age. With this lets write out what we know:
[tex]d = 7[/tex]
[tex]o = d + 2 = 7 + 2 = 9[/tex]
[tex]o = j - 8 + 3 = j - 5[/tex]
[tex]9 = j - 5[/tex]
[tex]j = 9 + 5 = 14[/tex]
