Answer:
y = - [tex]\frac{1}{2}[/tex] x - [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 5) and (x₂, y₂ ) = (3, - 6)
m = [tex]\frac{-6+5}{3=2}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, - 5 ) , then
- 5 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = - 5 + [tex]\frac{1}{2}[/tex] = - [tex]\frac{9}{2}[/tex]
y = - [tex]\frac{1}{2}[/tex] x - [tex]\frac{9}{2}[/tex] ← equation of line

Answer:
592
Step-by-step explanation:
Surface area of a rectangular prism = 2lw + 2lh + 2wh
where w = width, h = height and l = length
These are the given dimensions...
length = 12 cm
width = 8 cm
height = 10 cm
To find the surface area we plug in the given values into the formula
[tex]SA=2(12)(8)+2(12)(10)+2(10)(8)\\12*8=96\\96*2=192\\12*10=120\\120*2=240\\10*8=80\\80*2=160\\160+240+192=592[/tex]
Hence, the surface area of the rectangular prism is 592

What is the INTERQUARTILE RANGE for the data: , 3, 4, 4, 6, 7, 7, 9,
Answer:
The interquartile range for this data set is 3.
Step-by-step explanation:
We are given the data set : 3, 4, 4, 6, 7, 7, 9
In order to find the interquartile range, we can create a box plot for this data set. Each box plot contains a minimum, lower quartile, median, higher quartile, and maximum. Let's find the minimum and maximum before the others as it is the easiest one to identify. The minimum here would be 3 since that's the lowest number here in this data set. The maximum here would be 9 since that's the highest number here in this data set. Before we find the lower and higher quartile, let's find the median first since that way, we don't get mixed up between so many numbers. To find the median, you need to find the value that lies at the middle point throughout the data set. Since there are 7 values in this data set which is a odd number, all we need to do is cross out the first and last value as each set goes by.
3, 4, 4, 6, 7, 7, 9
4, 4, 6, 7, 7
4, 6, 7
6
The work above shows each set of the first and last value getting shorter and shorter, so the median of the data set would be 6. The values, 3, 4, and 9 have already been used. Now that we know the median, the second lowest number here is 4 (lower quartile) and the second highest number here is 7 (higher quartile). In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.
7 (higher quartile) and 4 (lower quartile) = 3 (interquartile range)
Therefore, the interquartile range for this data set is 3.

Whats the difference between a subset and a proper subset? {5,8} {2,5,8} Is {5,8} a subset of {2,5,8}.
Answer:
[tex]\{5,8\}[/tex] is a subset of [tex]\{2,5,8\}[/tex]
Step-by-step explanation:
Required
Difference between subset and proper subset
To answer this question, I will use the following illustration.
[tex]A = \{1,2,3\}[/tex]
[tex]B = \{2,3\}[/tex]
[tex]C = \{1,2,3\}[/tex]
In the above sets, set B is a proper subset of set A because all elements of B can be found in A, but not element of A can be found in B.
Set C is a subset of A because [tex]A = C[/tex]
Using the above illustration, we have:
[tex]\{5,8\}[/tex] and [tex]\{2,5,8\}[/tex]
[tex]\{5,8\}[/tex] is a subset of [tex]\{2,5,8\}[/tex], because 5 and 8 are in [tex]\{2,5,8\}[/tex] but 2 which ca be found in [tex]\{2,5,8\}[/tex] is not in [tex]\{5,8\}[/tex]

What is the value of "x"?
Answer:
my first thought was B but C has 2 similarities in 2 answered B is 4 D is 7.5, but C has a 4 and a .5 so try C
Answer:
Option C, 4.5
Step-by-step explanation:
We can say that;
8/6 = 6/x
=> [tex]\frac{8}{6} x=6\\[/tex]
=> x = [tex]\frac{6}{(8/6)}[/tex]
=> x = 4.5

2x-
:-1)2x² +9
He was left with a remainder of zero. Which of the following statements must
be true?
A.
must be a root of the polynomial 2x² +9x-5.
o
B. O must be a root of the polynomial 2x² +9x-5.
O c.
must be a root of the polynomial 2x² +9x-5.
D. 5 must be a root of the polynomial 2x² + 9x-5.
Answer: C: x = 1/2
Step-by-step explanation:
The solution is , O c. 1/2 must be a root of the polynomial 2x² +9x-5.
What are Polynomials?Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.
here we have this:
Considering the provided mathematical operation, we are going to identify wich is the correct statement, so we obtain the following:
Since the remainder is zero, it means that setting the divisor and quotient equal to zero gives us the roots, then we have:
2x-1=0
2x=1
x=1/2
and, we have,
x+5=0
x=-5
Finally we obtain that the roots are 1/2 and -5, then the correct answer is the option C.
Hence, The solution is , O c. 1/2 must be a root of the polynomial
2x² +9x-5.

Answer:
B
Step-by-step explanation:
1) use a proportion to find how many students chose pizza
30 : 100 = x : 80
x = (80 x 30)/100 = 24
2) use a proportion to find how many students chose salad
10 : 100 = x : 80
x = (80 x 10)/100 = 8
3) solve the question
24 - 8 = 16
Answer:
12 STUDENTS CHOSE HAMBURGERS
24 STUDENTS CHOSE PIZZA
16 STUDENTS CHOSE SANDWHICHES
20 STUDENTS CHOSE HOT DOGS
8 STUDENTS CHOSE SALAD
24 = PIZZA
8 = SALAD
8 - 24 = 16 SO B

Step-by-step explanation:
3a-2b=14. 3a+2b=28
..
Answer:
a = 7
b = 3 1/2
Step-by-step explanation:
if you add the equations together then the 'b' will zero out
6a = 42
a = 7
substitute 7 for 'a' to solve for 'b'
3(7) - 2b = 14
21 - 2b = 14
-2b = -7
b = 7/2 or 3 1/2
