Step-by-step explanation:

Which of the 4 has the greatest rate of change
For Graph (A):
We start by picking any two equivalent points on the table:
[tex](x_1,y_1) = (0,1)[/tex]
[tex](x_2,y_2) = (2,5)[/tex]
Next, we determine the slope, m:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5-1}{2-0}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m = 2[/tex]
This represents the rate of change:
For (B): [tex]y = 3x + 7[/tex]
An equation is of the form:
[tex]y = mx + b[/tex]
Where
m represents slope or rate of change:
By comparison:
[tex]m = 3[/tex]
For table (C):
We start by picking any two equivalent points on the table:
[tex](x_1,y_1) = (1,7)[/tex]
[tex](x_2,y_2) = (2,12)[/tex]
Next, we determine the slope, m:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12-7}{2-1}[/tex]
[tex]m = \frac{5}{1}[/tex]
[tex]m = 5[/tex]
This represents the rate of change:
For (D):
The $1.00 paid every week represents the rate of change.
So:
[tex]m = 1[/tex]
For A - D:
The rate of change are:
[tex]A = 2[/tex]
[tex]B = 3[/tex]
[tex]C = 5[/tex]
[tex]D = 1[/tex]
5 is the greatest.
Hence, (c) has the greatest rate of change

Find the average rate of change for the given function from x = −1 to x = 2.
A.) −2
B.)−1
C.)1
D.) 2
Given:
The table of values.
To find:
The average rate of change for the given function from x = −1 to x = 2.
Solution:
From the given table it is clear that y=-3 at x=-1 and y=3 at x=2.
Formula for average rate of change is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Using the above formula, the average rate of change for the given function from x = −1 to x = 2 is
[tex]m=\dfrac{3-(-3)}{2-(-1)}[/tex]
[tex]m=\dfrac{3+3}{2+1}[/tex]
[tex]m=\dfrac{6}{3}[/tex]
[tex]m=2[/tex]
Therefore, the correct option is D.

Which fraction is greater than 1/2 and less than 3/4 ?
Answer:
a. [tex] \frac{2}{3} [/tex]
Step-by-step explanation:
The fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex] and less than [tex] \frac{3}{4} [/tex].
How do we know this? See below how the fractions are compared together.
First, compare [tex] \frac{2}{3} [/tex] and [tex] \frac{1}{2} [/tex].
Find a common denominator for both fractions:
Common denominator of 2 and 3 would be 6. Therefore, multiply as follows:
[tex] \frac{2 \times 2}{3 \times 2} = \frac{4}{6}[/tex] and
[tex] \frac{1 \times 3}{2 \times 3} = \frac{3}{6} [/tex].
Compare the numerators. Which one is greater?
Form the calculation above:
[tex] \frac{2}{3} = \frac{4}{6} [/tex] has a numerator of 4.
.
[tex] \frac{1}{2} = \frac{3}{6} [/tex] has a numerator of 3.
Since 4 is greater than 3, therefore, the fraction, [tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex].
✍️Compare [tex] \frac{2}{3} [/tex] and [tex] \frac{3}{4} [/tex].
Find a common denominator for both fractions
[tex] \frac{2 \times 4}{3 \times 4} = \frac{8}{12} [/tex] and
[tex] \frac{3 \times 3}{4 \times 3} = \frac{9}{12} [/tex]
Comparing their numerator, 8 is less than 9, therefore:
[tex] \frac{2}{3} [/tex] is less than [tex] \frac{3}{4} [/tex].
✔️We can conclude that:
[tex] \frac{2}{3} [/tex] is greater than [tex] \frac{1}{2} [/tex], and less than [tex] \frac{3}{4} [/tex].

Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.
Answer:
II. One and only one solution
Step-by-step explanation:
Determine all possibilities for the solution set of a system of 2 equations in 2 unknowns. I. No solutions whatsoever. II. One and only one solution. III. Many solutions.
Let assume the equation is given as;
x + 3y = 11 .... 1
x - y = -1 ....2
Using elimination method
Subtract equation 1 from 2
(x-x) + 3y-y = 11-(-1)
0+2y = 11+1
2y = 12
y = 12/2
y = 6
Substitute y = 6 into equation 2:
x-y = -1
x - 6 = -1
x = -1 + 6
x = 5
Hence the solution (x, y) is (5, 6)
Hence we can say the equation has One and only one solution since we have just a value for x and y

Megan's room was remodeled. The new area of the room is 175% of the previous area. Only the length of the room changed. The width of the original room is 4m and the length of the original room is 4m. If the new room adds X to the length, what is the new expression for the new area? How many square meters has Megan's room increased? Explain how you solved the new area.
Answer:
new area = 7m (length) x 4m (width) = 28; an increase of 12 sq meters
Step-by-step explanation:
Original area must have been 16 because both the length and width were 6 meters.
175% of 16 is 12, meaning the length must be increased from 4 to 7 to get 28 when multiplied by a width of 4m

12. John borrowed $80 from his sister, Joan. He agreed to pay her back at a rate of $6 per
week. Create a function, P, that gives the amount of money that john still owes Joan after
w weeks.
12 (b) John told Joan that he will have paid her back all of the money, after making
payments for 13 weeks.. Explain why John is incorrect?
Answer:
P = 80 - 6wStep-by-step explanation:
Initial amount = $80Payment each week = $6Required function:
P = 80 - 6wTime required to pay all money. At this time P = 0
0 = 80 - 6w6w = 80w = 80/6w = 13.33Since w > 13, John needs 14 weeks
Why do we convert from a mixed number to an improper fraction by multiplying the denominator of the fraction by the whole number and then adding the numerator?
A mixed number to an improper fraction by multiplying the denominator of the fraction by the whole number and then adding the numerator
What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
To convert a mixed number to an improper fraction , we need to follow these three steps :
Step 1 : Multiply the whole number by the denominator
Step 2 : Add the answer from Step 1 to the numerator
Step 3 : Write answer from Step 2 over the denominator
Take for example :
Let the number be x = 5 5/9
Step 1 :
Multiply the whole number by the denominator
9 × 5 = 45
Step 2 :
Add the answer from Step 1 to the numerator
45 + 5 = 50
Step 3 :
Write answer from Step 2 over the denominator
50/9
Therefore , the mixed number 5 5/9 is converted to its improper fraction as 50/9

Step-by-step explanation:
Given:
[tex] \frac{2}{3}*1\frac{3}{4} [/tex]
Required:
Evaluate
SOLUTION:
To evaluate, we need to convert the mixed fraction to improper fraction, then multiply both fractions together.
Thus:
[tex] \frac{2}{3}*\frac{7}{4} [/tex]
Multiply the numerators together, and multiply the denominators together
[tex] = \frac{2 \times 7}{3 \times 4} [/tex]
[tex] = \frac{14}{12} [/tex]
Simply the fraction by dividing the numerator and denominator by 2

Find the angle of rotation about the center of the square that maps A to C.
The angle of rotation to map A into C is 180°.
How to find the angle of rotation?The rotation is around the center of the square. Let's assume that the center coincides with the origin of a coordinate axis.
Then we would have A on the second quadrant and C on the fourth quadrant.
Then we need to apply a rotation of two quadrants, remember that each quadrant has an angle of 90°, then a rotation of two quadrants has an angle of 2*90° = 180°.
The correct option is 180°.
