Answer:Yes it is proportional because w=kp k=paper weight which is constant. The relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional.
Step-by-step explanation:
Answer: Yes it is a direct proportional relationship
================================================
Explanation:
The equation is in the form y = kx, where
x = number of sheets of paper
k = weight of 1 sheet of paper
y = weight of all the x sheets of paper
x is some nonnegative whole number. The values of y and k are some nonnegative real numbers (aka any decimal values).
Note how if we had x = 0 pieces of paper, then y = 0 is the weight. So no paper leads to no weight. This visually is shown by the line y = kx going through the origin. All direct proportion equations go through the origin.
Each time we add a sheet of paper, we add on k ounces or k grams, or whatever units you're working with. The amount is constant assuming you are dealing with the same type of paper. Comparing y = kx with y = mx+b, we see that k plays the role of the slope or rate of change.

6) 2x + 3y = -1
3x + 4y = -4
Answer:
x = -8
y = 5
Step-by-step explanation:
2x = -3y-1
x = (-3y-1)/2
3x + 4y = -4
3[(-3y-1)/2]+4y = -4
(-9y-3/2)+4y = -4 (x2 all)
-9y-3+8y = -8
-9y+8y = -8+3
-y = -5
y = 5
3x+4.5 = -4
3x+20 = -4
3x = -24
x = -8
checking:
2.(-8)+3.5 = -1
-16+15 = -1 (checked)
what is the answer to x - 8 < -2
Answer:
X < 6
Step-by-step explanation:
Add 8 to both sides
x < 6
Answer:
X<6
Step-by-step explanation:
x-8<-2
So first off, you want to get X by itself. To do that you have to do the opposite of what the number is. If the number is negative you add it. If the number is positive, you subtract it. What you do on one side, you do on both.
x-8<-2
+8 +8
X<-2+8
Next, You need to add alike terms.
X<6

Y
Answer:
Step-by-step explanation:
both of those equations that are in the system are lines
first line it has a y-intercept at (0, -4) and a slope -1/2 so you can use that to
find another point ( 2 ,-5)
Since the equation has ≥ DRAW a solid line trough points (0, -4) and (2,-5)
Now highligt above the line since (0,0) cheks for the equation
second line goes troughh the points (0,1) because of y-intercept and point (1,2) because the slope is m=1
draw a solid line trough those points and highlight under the line
the intersection of the 2 highlighted ares is your solution

What is the y-intercept of the equation?
Answer:
6
Step-by-step explanation:
We need to make the 2y into just y, so divide the whole equation by 2. Now you have
y = 3x + 6. Since 6 represents B in the equation, and b is the y-intercept, the y-intercept is 6

I need help with this, I can't figure it out.
Answer:
- 4, 13, - 21, 47
Step-by-step explanation:
Using the recursive rule and a₁ = - 4 , then
a₂ = - 2a₁ + 5 = - 2(- 4) + 5 = 8 + 5 = 13
a₃ = - 2a₂ + 5 = - 2(13) + 5 = - 26 + 5 = - 21
a₄ = - 2a₃ + 5 = - 2(- 21) + 5 = 42 + 5 = 47
Thus the first 4 terms are - 4, 13, - 21, 47

Victoria uses
3/16
cup of flavored syrup to make an Italian soda. She has 2 cups of flavored syrup left. How many Italian sodas can she make?
A.
9 3/8
B.
10 2/3
C.
11 1/4
D.
12 1/2
Answer:
B. or 10 2/3
Step-by-step explanation: Because if she had only 2 cups left then 1 cup can make 5 drinks so 10 then the rest would be a fraction.
She can make 32/3 of Italian sodas with 2 cups of flavored syrup.
What is a fraction?
A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Victoria uses 3/16 cups of flavored syrup to make an Italian soda.
Assume that 3/16th of x is 1.
∴ (3/16)x = 1.
3x/16 = 1.
3x = 16.
x = 16/3,
Now from 2 cups of flavored syrup, we can make 2x of Italian soda.
Which is (16×2)/3.
= 32/3

A random two digit number (10-99) is drawn. Find each probability
1. p(32)
2. p(odd number)
3. p(a multiple of 5)
My teacher gave an assignment on this and didn't even teach how to do it.
Given that two digit numbers are used and one digit is drawn randomly.
Sample space = {10,11,...99}
n(S) = 90
32 is only one number favorable
Hence P(32) = 1/90
----------------------------
Odd numbers are exactly 45.
Hence prob (odd number) = 45/90 = 1/2
-------------------------------------
Multiples of 5 are 10,15,.....95
There are exactly 18 numbers.
Hence P(a multiple of 5) = 18/90 =1/5
