What is the slope of the line that passes through the given points?
(-1, -5) and (-12, -5)
Watch out for those negative signs!
Select one:
a.
0
b.
undefined (this means you get an answer like 5/0, you CANNOT divide a number by 0!)
c.
10/13 fraction
d.
13/10 fraction
Answer:
The answer is A. 0
Step-by-step explanation:
If you graph the equation it shows a straight horizontal line and that makes it zero
Answer:
A) 0
or m = 0
Step-by-step explanation:
Slope is zero, because it's just a straight horizontal line.
You can tell when you graph it or by the fact that they both have the same y-value, in this case -5.

What is m∠JNM? Line J L and line M K slightly inclined with horizontal intersects at N. The upward and downward angles of the intersecting lines are obtuse. The left and right angles of the intersecting lines are acute. The measure of angle J N M is labeled as left parenthesis 4 x plus 6 right parenthesis degrees. The measure of angle L N K is labeled as left parenthesis 7 x minus 21 right parenthesis degrees.
Answer:
JNM=42
Step-by-step explanation:
JNM is equal to LNK so you can set the equations equal to each other.
7x-21=4x+6, subtract 4x from both sides
3x-21=6, add 21 to both sides
3x=27, divide by 3
x=9, then you plug it into an equation
4 times 9 + 6
36+6
42
<JNM = [tex]42[/tex] degrees.
What is horizontal angle?The angle made by two ground lines is measured horizontally , and is called a horizontal angle.
According to the question
Line J L and line M K slightly inclined with horizontal intersects at N.
<JNM = <LNK
[tex]4x + 6 = 7x - 21[/tex]
Subtract 4x from both sides
[tex]6 = 3x -21[/tex]
[tex]3x=27[/tex]
Divide by 3
[tex]x=\frac{27}{3}[/tex]
[tex]x =9[/tex]
<JNM = [tex]4x+6[/tex]
<JNM = [tex]4(9)+6[/tex]
<JNM = [tex]42[/tex] degrees

Which of the following functions best describes this graph?
10
Answer:
A
Step-by-step explanation:
vertex = (-4, -4)
vertex form:
y = a(x-h)^2 + k
__________
y = (x- (-4))^2 + (-4)
y = (x+4)^2 -4
y = (x+4)(x+4) - 4
y = x^2 + 8x + 16 - 4
y = x^2 + 8x + 12
answer: A
To make papier-mâché, Emma uses 3/4 cup of white school glue for each batch. For a big project, she will make 11 batches of papier-mâché. Emma has half of 1-gallon bottle of white school glue. Does Emma have enough glue?
Emma will not have enough glue since she'll have 10 2/3 rather than 11 batches.
Note that 1 gallon = 16 cups
Since Emma has half of 1-gallon bottle of white school glue, this means that she has 1/2 × 16 = 8 cups
Since Emma uses 3/4 cup of white school glue for each batch, therefore the number of batches that van be made with 8 cups will be:
= 8 ÷ 3/4
= 8 × 4/3
= 10 2/3
Therefore, Emma will not have enough glue since she'll have 10 2/3 rather than 11 batches.

Ethan, Caleb, and Jayden went to a bakery to buy desserts. Ethan bought 2 cupcakes, 2
brownies and a pie for $20. Caleb bought 4 cupcakes, 4 brownies and a pie for $44, Jayden
bought 5 cupcakes and 6 brownies for $40. Write a system of equations to represent is
situation. Convert the system to a matrix and find the cost of 1 cupcake, 1 brownie, and 1
pie to the nearest cent.
Answer:
x = 32
y = -20 and
z = -4
Step-by-step explanation:
Cupcakes = X
Brownies = Y
Pies = Z
Ethan = 2x+2y+z = 20
Caleb = 4x+4y+z = 44
Jayden = 5x+6y = 40
-1(2x+2y+z=20) =
(-2x - 2y - z = -40) + (4x+4y+z=44)
= 5x + 6y = 40
-3(2x+2y=24 =
(-6 - 6y = -72) + (5x + 6y = 40)
= - x = - 32
= x = 32
5 (32) + 6y = 40
= 160 + 6y = 40
6y = 40 - 160
y = 120/6
y = - 20
2(32) + 2(-20) + z = 20
64 - 40 + z = 20
z = 20 - 24
z = -4

Answer:
C.
Step-by-step explanation:
She needs 160 for a free ticket and get 85 for signing up.
Every time she goes, she get 12.5 points
160=85+12.5v
The answer would be C
Reason:
We eliminate B and D as they do not have a total of 160 points.
We are now left with A and C
A shows that she would need to earn 85 points three times which is incorrect as she receives 85 points 1 time after signing up. Therefore we eliminate A.
We are now left with C
C shows that the total amount of points she would need to earn a free ticket are 160 points.
It also shows that she would receive 85 points 1 time after signing up.
It also shows that the remaining points she would get are from strictly visiting the movie theater.

Step-by-step explanation:
Sn = n/2(2a+(n-1)d)
a=6
a+ 4d= 18
6 +4d= 18
4d = 12
d = 3
162= n/2(12+(n -1)3)
324=n(12 + 3n-3)
324=12n + 3n^2 - 3n
3n^2 + 9n-324=0
3n^2+ 36n-27n -324 =0
3n(n+12) -27(n+12)= 0
3n-27 =0; n+ 12=0
n=9 ; n= -12
since n can't be negative n=9

Rosa says she can break this array into 3 different sets of two smaller arrays . Is Rosa correct ? Explain . The array is a 6 by 8.
Answer:
yes
Step-by-step explanation:
because 6X8=48 and 48 dived by 3 equals 16
Arrays are dataset that are represented in rows and columns. Rosa's claim is correct.
What is an array?An array is a linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations.
From the question, we have:
6 rows and 8 columns
The number (n) of elements in the array is: n = Rows × Columns.
So, we have: n = 6 × 8 =48
Express as sum of three numbers, that is n=12+16+20
Express each term as a product, that is n=2 × 6 + 4 × 4 + 4 × 5
The above expression means that, the array can be split to:
An array of 2 by 6
An array of 4 by 4
An array of 5 by 4
Hence, Rosa is correct.
