6+3/-3=Neg 3
Answer:
C. -3
Step-by-step explanation:
You can do this using two different methods.
First, slope is written rise over run, or y over x. We can find two points and count how much we need to rise and run. The graph already includes the points (2,-3) and (-1, 6), which we will use. If you carefully look at the graph, you can see that if you start from the point (2,-3), you can rise 9 and run -3 to get to the point (-1, 6), which brings me to the next step. As I stated in the beginning, slope is written rise over run. Therefore, the slope is 9/-3, which simplifies to -3, answer choice C.
Another way you can do this is subtracting the y's and subtracting the x's in the same order. The y's go over the x's, and is basically written as a fraction. For this method, we still need two points. We will use the same points as above and listed on the graph, points (2,-3) and (-1, 6). The y's are -3 and 6, and the x's are 2 and -1. Now, subtract.
-3-6 =-9=-3
2-(-1)= 3
As you can tell, both methods of solving for slope worked, and the answer is choice C.
I hope this helps!! Have a great day, and thanks for the points (^人^)

En una baraja completa de naipes ingleses (108 naipes), se selecciona un naipe, ¿Cuál es la probabilidad de que esta sea un joker rojo?
Por cada baraja de naipes de 54 cartas hay 1 joker rojo. Si esta baraja tiene 108 cartas, entonces habran 2 joker rojos.
Probabilidad de sacar 1 joker rojo = 2 / 108 = 1 / 54 = 0.185185 = 1.85%

probabilidad de sacar un voto nulo o blanco = 1 - probabilidad de sacar un voto para el alcalde B - probabilidad de sacar un voto para el candidato A = 1 - 0.5 - 0.3 = 0.2 = 20%
La probabilidad de que, al seleccionar una persona, esta guste del basquetbol es de 0,5, la probabilidad de que esta guste del futbol es de 0,7, la probabilidad de seleccionar a alguien que guste de alguno de los dos deportes es del 0,85 ¿Cuál es la probabilidad de seleccionar a una persona que guste de ambos deportes?
probabilidad que le gusten los dos deportes = probabilidad que le guste el futbol x probabilidad que le guste el basquetbol = 0.5 x 0.7 = 0.35 = 35%

How many boxes does each girl sell?
Define your variables:
X =
Y =
boxes.
boxes, and Ayan sold
Kay sold
Answers
Answer:
Kay sold 6 boxes and Ayan sold 19 boxes
Step-by-step explanation:
Let x = number of boxes Kay sells
y = number of boxes Ayan sells
Then the equations will be:
[tex]x+y = 25\\x = y-13[/tex]
We can solve the system by using substitution method
Putting x = y-13 in equation 1
[tex]y-13+y = 25\\2y -13 = 25\\2y = 25+13\\2y = 38[/tex]
Dividing both sides by 2
[tex]\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]
Putting y = 19 in equation 2
[tex]x = y-13\\x = 19-13\\x = 6[/tex]
Hence,
Kay sold 6 boxes and Ayan sold 19 boxes

Katelyn is training for a marathon. This week she ran 6 miles less than 2 times the number of miles she ran the previous week. She ran a total
of 42 miles in the two weeks.
Which system of equations can be used to find the number of miles she ran this week, r, and the number of miles she ran the previous week,
p?
Answers
Answer:
The system of Equations =
r = 2p - 6........ Equation 1
r + p = 42 ........Equation 2
Hence:
the number of miles she ran this week = r = 26 miles
the number of miles she ran the previous week = p = 16 miles
Step-by-step explanation:
Let the number of miles:
the number of miles she ran this week = r
the number of miles she ran the previous week = p
Katelyn is training for a marathon. This week she ran 6 miles less than 2 times the number of miles she ran the previous week.
r = 2 × p - 6 miles
r = 2p - 6........ Equation 1
She ran a total of 42 miles in the two weeks.
r + p = 42 miles
r + p = 42 ........Equation 2
Which system of equations can be used to find the number of miles she ran this week, r, and the number of miles she ran the previous week,p?
The system of Equations =
r = 2p - 6........ Equation 1
r + p = 42 ........Equation 2
We substitute 2p - 6 for r in Equation 2
2p - 6 + p = 42
3p = 42 + 6
3p = 48
p = 48/3
p = 16 miles
Solving for r
r = 2p - 6........ Equation 1
r = 2(16) - 6
r = 32 - 6
r = 26 miles
Hence:
the number of miles she ran this week = r = 26 miles
the number of miles she ran the previous week = p = 16 miles

x ≤ y
means that x is less than or equal to y.
(both of these signs can be in the other direction, take that in mind).
A) " a is always less than another number b"
Here we should have:
a < b.
a is always less than the other number b.

A bathtub drains at a rate of 4 1/5 liters of water in 1/5 of a minute. How many liters of water does the bathtub drain per minute
Answers
Answer:
I think the answer is 252 liters a minute.
Step-by-step explanation:
I got 252 liters a minute because I had to first put 4 1/5 as a fraction and it was 21/5. In ever minute there are 60 seconds. I then multiplied 21/5 times 60 to get me to 252 liters. To double check your work you have to divide 252 by 60. When you divide 252 by 60 you would get 4.2 which reduces to 4 1/5 which makes 252 liters per minute the right answer. Hope this helps.
