Hi Jah sis own joss joss kale be 88 i87
Answer:
Students altogether liked cola the best 26
Step-by-step explanation:
Total no of pupils = 60
Boys = 32
girls = 28
we will make a table
Gender cola milk water total
Boys 12 4 32
Girls 9 28
we can find the missing numbers
Let x be for milk
In boys 12 + x + 4 = 32
x = 16
In girls
as 21 liked milk altogether
so girls = 21 - 16 = 5
Gender cola milk water total
Boys 12 16 4 32
Girls 5 9 28
For cola let y
in girls
y + 5 + 9 = 28
y = 14
Gender cola milk water total
Boys 12 16 4 32
Girls 14 5 9 28
Altogether cola = 14 + 12 = 26
Divide the 10 by 4, which makes the x be 2.5. You can check it by multiplying 4 by 2.5, which will give you 10.
Answer:
c. 25/100
Step-by-step explanation:
The given fraction is 1/4.
Here we need to find the equivalent to 1/4.
It c. 25/100
Let me explain.
Multiply 1/4 by 25 both the numerator and the denominator.
1/4 *25/25 = 1*25 / 4*25
= 25/100
All other fractions are not equivalent to 1/4
Answer: c. 25/100
Thank you.
Okay, let me just make this a little clearer. Hopefully, this is what you meant:
A. y - 8 = -4(x + 4)
B. y - 8 = 4(x + 4)
C. y + 8 = 4(x - 4)
D. y + 8 = -4(x - 4)

This can also be written as y2 - y1 = m(x2 - x1).
Your M is your slope.
Both A and D have their m as a negative 4. Because you are looking for a positive slope, immediately cancel those answers.
* note that you could have also put them in a more standard form and discovered m which is the x in bx.
Now, you are looking for an equation that contains (4,-8).
Because it is written as y2-y1, your y's are actually points if you were to find another slope or something. This part is a bit hard to explain, but -8 is only found in the y coordinate place in answer B. Your answer would be B. For more explanation on that, there's this great site called coolmath.com and if you search for finding the equation of two points, it explains it much better on there, but I would not want to plagiarize.
The answer is B.
