Answer:
B or -2/7 should be correct
Step-by-step explanation:
First, I would find out the improper fraction of -3 1/2
The improper fraction of -3 1/2 is -7/2
To find the multiplicative inverse, we will flip the numerator and the denominator.
Multiplicative inverse of -7/2 = 2/-7
2/-7 is a weird way to write a fraction, so to convert into a reasonable fraction, we will multiply both the numerator and denominator by -1.
2/-7 x -1/-1 = -2/7
Therefore, B should be your answer

Of the last 18 trains to pull into Castroville Station, 12 were full. Considering this data, how many of the next 12 trains would you expect to be full?
Answer:8
Step-by-step explanation:
There are 12 of the next 12 trains would expect to be full.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Based on the information provided, it seems that 12 out of the last 18 trains to pull into Castroville Station were full, which is a proportion of 12/18 or 2/3.
Therefore, if the same proportion of full trains holds in the future, one would expect 2/3 or 8 of the next 12 trains to be full.
This prediction is based on the assumption that the proportion of full trains remains constant.
Thus, there are 12 of the next 12 trains would expect to be full.

describe distributive property
Answer:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

A curve is given the equation xy=25 and the equation of a line y=mx+b.
i. Express m in terms of b given that the line and the curve have one and only one point of intersection.
ii. If the line intersects the curve in two distinct points, find the set of values of b, given m=-5
Answer:
Below in bold.
Step-by-step explanation:
i, This is a rectangular hyperbola with symmetry about the line y = -x
If it touches the graph at one point only then
y = 25/x
y = mx + b so
25/x = mx + b
mx^2 + bx + 25 = 0
Using the quadratic formula:
x = (-b + sqrt(b^2 - 25*4*m)) / 2m
Now there's only one value of x so
b^2 - 25*4*m = 0
b^2 = 100m
m = b^2/100.
m = +/-b/10.
ii In this case b^2 > 100m
If m = |-5|
b^2 > 500
b > +/-√500
So b > √500 or b < -√500.
A triangle has two sides of length 17 and 19. What is the smallest possible whole-number length for the third side?
Answer:
3
Step-by-step explanation:
A triangle has two sides of length 17 and 19. What is the smallest possible whole-number length for the third side?
To solve for the above question, a rule applies.
The rule states that:
The sum of any 2 sides must be greater than than the third side.
The possible values for the third side are
19 - 17 < x < 19 + 17( x is the third side )
2 < x < 36
Thus the smallest possible whole number is 3

Do 2b+b and 3b have the same value for all values of b
Answer:
Expression 2b+b and 3b have same values for all values of b.
Step-by-step explanation:
Given the two expression 2b+b2b+b and 3b3b and values of b as 1, 2 and 3.
Consider first expression that is, 2b+b2b+b .
Substituting the value of b=1b=1 ,
2\left(1\right)+\left(1\right)=2+1=32(1)+(1)=2+1=3 ....1
Substituting the value of b=2b=2 ,
2\left(2\right)+\left(2\right)=4+2=62(2)+(2)=4+2=6 ....2
Substituting the value of b=3b=3 ,
2\left(3\right)+\left(3\right)=6+3=92(3)+(3)=6+3=9 ....3
Consider second expression that is, 3b3b .
Substituting the value of b=1b=1 ,
3\left(1\right)=33(1)=3 ....4
Substituting the value of b=2b=2 ,
3\left(2\right)=63(2)=6 ....5
Substituting the value of b=3b=3 ,
3\left(3\right)=93(3)=9 ....6
For value of b=1, equation 1 and equation 4 are same, for value of b=2, equation 2 and equation 5 are same and for value of b=3 equation 3 and equation 6 are same.
Therefore both expression are same for all values of b.

f(x) = 4x?
Answer:
Step-by-step explanation:
that options given seem wrong but what do i know thats just difficult dude im just in the 4th grade
Answer:
4th option
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject, that is
y = 4x ( divide both sides by 4 )
[tex]\frac{1}{4}[/tex] y = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = h(x) = [tex]\frac{1}{4}[/tex] x

Step-by-step explanation:
These are vertical angles so they're equal to each other:

2x - 5x = -20 - 13
-3x = -33
x = 11

Desmond really like Legos. Last Saturday Desmond counted his Legos and realized that
he has 65 altogether! Desmond has 7 less green Legos than red Legos, and the amount of
blue Legos he has is two more than three times his red Legos. How many of each color
Lego does Desmond have?
Answer Quick.
Only reply if you have the answer please
Answer: 14 red, 7 green, 44 blue
Step-by-step explanation:
First, use the letter r as a variable to represent the number of red Legos. The number of green Legos (g) is 7 less than the number of red Legos, or g = r-7. The number of blue Legos (b) is 2 more than 3 times the number of red Legos, or b = 3r+2. The total number of Legos is the number of red + green + blue Legos, which can be represented as 65 = r+g+b.
Substitute the equations for g and b in. This should give you a final equation of 65 = r+(r-7)+(3r+2). To solve for the number of red Legos, first add up all of the terms to get 65 = 5r-5. Now add 5 to each side (70 = 5r). Finally, divide each side by 5 (r = 14).
To find the number of green Legos, substitute the number of red Legos (14) into the equation for the green Legos (g = r-7). This should get you the equation g = 14-7 which simplifies to g = 7.
To find the number of blue Legos, substitute the number of red Legos (14) into the equation for the blue Legos (b = 3r+2). This gives you the equation b = (3*14)+2. First, multiply 3 and 14 to get b = 42+2. Finally, add them together to get b = 44.

Rule: y is 1/3 times as large as x. If x=0 y=? x=6 y=? x=12 y=?
Answer:
So for 0
0*1/3 = 0
6*1/3= 2
12*1/3= 4
Step-by-step explanation:
An equation is formed of two equal expressions. The value of y when the value of x is 0, 6 and 12 is 0, 2, and 4, respectively.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the statement that "y is 1/3 times as large as x", therefore, the rule can be written as,
y=(1/3)x
Now, the value of y for different value of x can be written as,
1.) When x=0
y = (1/3)x
y = (1/3)(0)
y = 0
2.) When x=6
y = (1/3)x
y = (1/3)(6)
y = 2
3.) When x=12
y = (1/3)x
y = (1/3)(12)
y = 4
Hence, the value of y when the value of x is 0, 6 and 12 is 0, 2, and 4, respectively.

Can u find the value of the x.
Answer:x=8
Step-by-step explanation:
x²-3x=-3x+64
- Add 3x to both sides
x²-3x+3x=-3x+3x+64
= x²=64
- Square both sides
√x²=√64
x=±8
- Since the question is asking for the positive value of x, the answer is 8.
