 which equation represents the line that passes through the points (3, 7) and (-1, -1)?
points: (3, 7) and (-1, -1)
slope (m) :
[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}[/tex]
========
[tex]\hookrightarrow \dfrac{-1-7}{-1-3}[/tex]
[tex]\hookrightarrow \dfrac{-8}{-4}[/tex]
[tex]\hookrightarrow 2[/tex]
Equation:
[tex]\sf y-y_1 = m(x-x_1)[/tex]
==============
[tex]\rightarrow \sf y-7 = 2(x-3)[/tex]
[tex]\rightarrow \sf y = 2x-6+7[/tex]
[tex]\rightarrow \sf y = 2x+1[/tex]
Answer:
[tex]y = 2x- 1[/tex]
Step-by-step explanation:
To determine which equation passes through the points (3, 7) and (-1, -1), we need to determine the slope of the equation. Then, we shall use point slope form to determine the equation of the line.
Determining the slope of the line:
[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run} } =\dfrac{\text{y}_{2} - \text{y}_{1} }{\text{x}_{2} - \text{x}_{1} }[/tex]
Substituting the points in the slope formula:
[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]
Simplifying the slope:
[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]
[tex]\text{Slope} =\dfrac{-8}{-4 } = 2[/tex]
Determining the equation of the line:
We shall use point slope form to determine the equation of the line.
[tex]\text{Point slope form:} \ y - y_{1} = m(x- x_{1} )[/tex]
Substitute the slope and the coordinates of any two points stated above.
[tex]y -7= 2(x- 3 ) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Using the point (3,7)}][/tex]
Simplify the equation and organize it to slope intercept form:
[tex]y -7= 2x- 6[/tex]
[tex]y = 2x- 6 + 7[/tex]
[tex]y = 2x+ 1[/tex]

How can you decompose the composite figure to determine its area? as a pentagon and four semicircles as two rectangles and four circles as a square and four semicircles as two triangles and four circles
Answer: as a square and four semicircles
Step-by-step explanation:
The composite shape area can be found by first decomposing the figure as: a square and four semicircles.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

10 identical copies of a movie will be stored on 40 computers such that each computer has at most 1 copy. How many different ways can the 10 copies be stored
We will see that there are 847,660,528 different ways in which the copies can be stored.
In how many ways can the 10 copies be stored?
So, we know that the copies can be stored in any of 40 computers, such that each computer can get, at most, one copy.
Then what we need to do is find how many different combinations of 10 computers can we make with the set of 40 computers, this is given by using the combination formula:
[tex]C(40, 10) = \frac{40!}{(40 - 10)!*10!} = \frac{40*39*38*37*36*35*34*33*32*31}{10*9*8*7*6*5*4*3*2} = 847,660,528[/tex]
This means that the 10 computes can be selected in 847,660,528 different ways, so there are 847,660,528 different ways in which the copies can be stored.

What is the volume of this pyramid? 32 cm 9 cm 15 cm
Answer:
720cm^3
Step-by-step explanation:
The volume of the pyramid with a = 9cm, b = 15cm and l = 32cm is 720cm^3.
Answer:
720³ cm
The formula for volume is...
length ×width ×heightWith that information, we should multiply the smaller numbers first.
[tex]B = \frac{1}{2} xy[/tex]
Replace the substituted parameters with 9 and 15, then multiply them and solve.[tex]B = \frac{1}{2}(9)(15) = \frac{135}{2}[/tex]
UseV for volume.[tex]V = \frac{1}{3} * \frac{135}{2} * 32 = 45 * 16[/tex]
Reducing the expression ↓[tex]V = 720^3~cm[/tex]
Hence, the volume is 720³ cm
A theater has 32 rows. The first row has 18 seats, second row has 21 seats, third row
has 24 seats, and so on. Determine the total number of seats in the theater.
Answer:
2064
Step-by-step explanation:
18 + 21 + 24 + ...
This is an arithmetic series with first term 18 and common difference 3.
The nth term is
18 + 3(n - 1)
The 32nd term is the number of seats in the 32nd row:
18 + 3(32 - 1) = 18 + 3(31) = 18 + 93 = 111
The sum of the series is:
n/2(a + L) = (32/2)(18 + 111) = 2064

The table shows input and output values for a liner function f(x). What is the positive difference of outputs for any two outputs that are two values apart? H E L P. 10 Points award!!
Answer:
If you observer the value of x=0 and x=1, you can conclude that every 1 value of x increased,
the f(x) will be increased by 0.5. The graph function should be:
f(x)= x/2A positive difference means that the value should be always positive.
To find 3 the positive difference of f(x) with 3 values of x apart, let use x=0 and x=0+3= 3. The difference would be:
f(x+3) - f(x)f(3)- f(0)=1.5 - 0= 1.5The answer would be: 1.5
