Step-by-step explanation:
To learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points, and I used my calculator to do so.

what is the vertical change from point A to point B ?
What is the horizontal change to point A to point B?
Answer:
Vertical change= 1
Horizontal change= 2
Rate of change= 1/2
Step-by-step explanation:
The vertical change is how many units you go up on the triangle and the horizontal change is how many units you go left or right on the triangle. The rate of change is the vertical change over the horizontal change. So that is why 1/2 is the rate of change. Have a great day!

The ratio of old books to the new books is new : old = 7 : 4.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, There are 11 books on a shelf, and 7 of these books are new.
So, The number of old books are (11 - 7) = 4.
So, In the self there is 7 new books and 4 old books.
Therefore the ratio of new books to old books,
new books : old books = 7 : 4.

What is the slope of a line with the equation y = 5x + ⅖ ?
Answer:
The slope would be 5
Step-by-step explanation:
The reason why it would be five is because the slope formula is y=mx+b with m being your slope and b being your y-intercept.
Answer:
slope: 5
Step-by-step explanation:
[tex]y=mx+b[/tex] is the equation used to find the slope of an equation. The slope is ALWAYS the "m" value. So.... in this equation y=5+2/5... the "m" value is 5.... making the slope of the equation 5.
Liza’s age is two more than thrice the age of her younger sister.if her sister is 5 years old, how old is Liza?
Answer:
17 years old.
Step-by-step explanation:
sisters age:5
5×3+2=17.
Answer:
Liza is 17 years old.
Step-by-step explanation:
Ley 'x' be the age of Liza's younger sister
As Liza’s age is two more than thrice the age of her younger sisterso the equation of Liza's age will be:
Liza's age = 3x+2
As x = 5 years is Liza's younger sister age
so
Liza's age = 3(5)+2
= 15+2
= 17 years
Therefore, Liza is 17 years old.

Hal owns a printing company. Last Christmas, he charged $8 for a set of 25 greeting cards and $14 for a set of 50. a. Find two ordered pairs that represent the situation. (8,25) (14,50)
Answer:
(8, 25) and (14, 50)
Step-by-step explanation:
Total cost of a set of cards = price per unit x number of cards
= p x n
Thus, the total cost of printing each set of cards depends on the price per unit and number of cards. So that it can be represented in ordered pair as: (p, n).
For the first set of greeting cards,
the cost of printing a card = $8.0
number of cards printed = 25
This can be represented in ordered pair as (8, 25)
For the second set of greeting cards,
the cost of printing a card = $14.0
number of cards printed = 50
This can be represented in ordered pair as (14, 50)
Thus, the two ordered pairs that can represent the situations are (8, 25) and (14, 50).

Which measure of Center would be most effected if 50 was added to the following data set? 10, 14, 15, 15, 18, 20
Answer:
The mean.
Step-by-step explanation:
The mean because 50 is a lot bigger number than the numbers in the list.
The median (the middle number in an ordered list) would still be 15. Also the mode (15) will also stay the same.
The original mean = sum of the 6 numbers divided by 6
= 92/5 = 15.3.
When 50 is added the mean is (92 + 50) / 7 = 20.3.
Answer:
The mean
Step-by-step explanation:
Because mean is the main measure of center that we solve first before solving the others

Mrs. Reyna is planning to fence her vacant lot for a parking space. The desired length of the lot is 6 m longer than its width. What will be the possible dimensions of the rectangular parking space if it should be less than 40m2?
(Hint: length x width = Area of rectangle)
Answer:
Step-by-step explanation:
Given
Area of the rectangle =Length × width
Given
The desired length of the lot is 6 m longer than its width, then L = 6+W
A = LW
40 = (6+W)W
40= 6W+W²
W²+6W -40 = 0
W²+10W-4W-40 = 0
W(w+10)-4(w+10) = 0
W+10 = 0 and w-4 = 4
W = -10 and w = 4
Width can't be negative
W = 4m
Since L = 6+w
L = 6+4
L = 10m
Hence the possible dimension s 4m by 10m
