If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..
A) the slope of the line AB
B) The length of the line AB
Answer:
Slope = 27/11AB = 29.15 uStep-by-step explanation:
Given :-
Two points are given to us .The points are A(7,15) and B(18,42)To Find :-
The slope of the line .The length of line AB .We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,
[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]
Plug in the respective values ,[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]
Hence the slope of the line is 27/11 .
[tex]\rule{200}2[/tex]
Finding the length of AB :-
We can find the distance between them by using the Distance Formula .[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]
Hence the length of AB is 29.15 units .

Answer:
x = [tex]\sqrt{14}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in both tight triangles.
First in the small triangle to find the third side ( hypotenuse ) h
h² = 1² + 1² = 1 + 1 = 2 ( take square root of both sides )
h = [tex]\sqrt{2}[/tex]
Now use the identity in the larger right triangle
x² + h² = 4²
x² + ([tex]\sqrt{2}[/tex] )² = 16
x² + 2 = 16 ( subtract 2 from both sides )
x² = 14 ( take square root of both sides )
x = [tex]\sqrt{14}[/tex]
Emily is encouraged to read more than 4 hours each week. It takes her 45 minutes to finish her first book. She divides the remainder of the time equally amongst the other six days. What is the minimum number of minutes she should read each day? Write and solve an inequality. put this is an inequality pls!!
Step-by-step explanation:
x > 4 hours/week
4 hours is 240 minutes
45 minutes/ 1st book
4 hours minus 45 minutes is 3 hours and 15 minutes
3 hours and 15 minutes = 195 minutes
195 minutes ÷ 6 = 32.5 minutes
make the formula working backwards
(240 - 45) ÷ 6 > x

Durning the summer , a shoe store sells sneakers and sandals at a ratio of 4:7 . If the store sells 164 pair of sneakers, how many pair of sneakers and sandals does the store sell in all ?
Answer:
x = number of pairs of sandals sold = 287
Total pair of sneakers and sandals sold = 451 pairs
Step-by-step explanation:
Sneakers = 4
Sandals = 7
Sneakers : sandals = 4 : 7
If the store sells 164 pair of sneakers
Let
x = number of pairs of sandals sold
Sneakers : sandals = 164 : x
Equate both ratios to find x
4 : 7 = 164 : x
4/7 = 164/x
4 * x = 7 * 164
4x = 1,148
x = 1,148/4
x = 287
x = number of pairs of sandals sold = 287
how many pair of sneakers and sandals does the store sell in all ?
Total pair of sneakers and sandals sold = Sneakers + sandals
= 164 + 287
= 451 pairs
Total pair of sneakers and sandals sold = 451 pairs

Elsa, Keith, and Lamar sent a total of 68 text messages during the weekend. Keith sent 8 more messages than Elsa. Lamar sent 2 times as many messages as Elsa. How many messages did they each send?
Answer:
Elsa sent 15, Lamar sent 30, and Keith sent 23
Step-by-step explanation:
If x=Elsa, L=Lamar, and K=Keith
2x=L
x+8=K
x+x+8+2x= 68
4x+8=68
4x=60
x=15
Then you plug 15 into x, and solve for each person.
(15)2=L
(15)+8=K

What is the area of rectangle ABCDABCDA, B, C, D? Please Help
Answer:
Step-by-step explanation:
The rectangle ABCD has vertices A(-2,2), B(6,2), C(6,3) and D(-2,3).
Now, length of side AB = [6 - (- 2)] = 8 units.
{Since the line AB is parallel to the x-axis, so the length of the segment AB will be the difference between the x-coordinates of the points A and B}
Again, line BC is parallel to y-axis and hence the length BC = (3 - 2) = 1 units.
Therefore, the area of the rectangle ABCD will be (8 × 1) = 8 sq. units. (Answer)

The 15th term of an arithmetic sequence is 21 and the common difference is -4.
(a) Find the first term of the sequence.
(b) Find the 29th term of the sequence.
(c) Find the sum of the first 40 terms of the sequence.
Answer:
a. Firat term of the sequence= 77
b. 29th term of the sequence= -35
c. Sum of the first 40 terms of the sequence= -40
Step-by-step explanation:
The first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.
Given that, [tex]a_{15} =21[/tex] and d=-4.
What is the nth term of the arithmetic sequence?The nth term of the arithmetic sequence is [tex]a_{n} =a+(n-1)d[/tex].
To find the first term of the sequence:
[tex]a_{15}[/tex]=a+(15-1)(-4)
⇒21=a+(15-1)(-4)
⇒a=77
To find the 29th term of the sequence:
[tex]a_{29}[/tex]=77+(29-1)(-4)=-35
To find the sum of the first 40 terms of the sequence:
The first n terms of a sequence [tex]=\frac{n}{2}[2a+(n-1)d)][/tex]
[tex]S_{40} =\frac{40}{2}[2 \times77+(40-1)(-4))][/tex]
=20(154-156)=-40
Therefore, the first term of the sequence is 77, the 29th term of the sequence is -35 and the sum of the first 40 terms of the sequence is -40.
