Multiplicative inverse of -3 6/11 ? In fraction form- please and thank you ^^
Answer:
Step-by-step explanation:
first you have to make this an improper fraction my multiplying -3 by 11 then add the product of that to 6 and put it all over 11
[tex]-3\frac{6}{11}[/tex] → [tex]-\frac{39}{11}[/tex]
once you get this you have to do the reciprocal of this to get them to equal 1
[tex]-\frac{39}{11}[/tex] → [tex]-\frac{11}{39}[/tex]
then multiply the number by the reciprocal
[tex]-\frac{39}{11}* -\frac{11}{39}=\frac{429}{429}=1[/tex]
Each gallon of gasoline costs $2.35. The equation y=2.35x can be used to represent this situation.
What is the constant of proportionality? Express your answer in decimal form.
Answer:
For every gallon of gas added to the tank, the buyer is charged $2.35
The constant of proportionality of the given equation y = 2.35x will be 2.35.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Let's x ∝ y
Then x = ky where k will be constant of proportional.
k = x/y which means when two variables are divided which were in proportion it will create a constant proportional.
So,
y /x = 2.35 will be constant of propotional.
Hence "The constant of proportionality of the given equation y = 2.35x will be 2.35".

Write the equation of the line that passes through the points (3, -4) and (-3, 0) in slope-intercept form.
Step 1: Use the slope formula y₂ - y₁/x₂ - x₁ to find the slope.
[tex]\frac{0 - (-4)}{-3 - 3}\\ \\\frac{4}{-6} = -\frac{2}{3}[/tex]
Step 2: Plug the slope we found and one point into the slope-intercept formula, y = mx + b.
[tex]y = mx + b\\\\0 = -\frac{2}{3}(6) + b\\\\0 = -4 + b\\\\4 = b[/tex]
Step 3: Put it all together.
[tex]y = -\frac{2}{3}x + 4[/tex]

Timothy and Alondra are cutting strips of poster paper for an art project.
Timothy cut 10 strips of poster paper that are each 3 feet inches long.
Alondra cut 10 strips of paper that are same length as Timothy’s strips of paper, but measured them as 106.68 centimeters long.
If Alondra cuts a strip of poster paper that is 220 centimeters long, what is the approximate length of the strip in feet that Timothy will measure.
please answer, fast!
Answer:
answer B
Step-by-step explanation:
I
there's 3 feet and 9 inches of paper on timothy's side
alondra cuts the zame amount of strips at 106.68m
there are 2.54 centimeters in one inch.
there are 12 inches in a foot
12 ×3 is 36 plus 9 is 45 inches
now, divide 106.68 by 2.54 to get 42 inches (we have 3 left over
if we subtract 220 by 106.68 we get 113.12
2.54 centimeters equals 1 inch, divide 113.12 to get 44.6
convert this to feet and we get 3 feet and 8 inches
3 feet 8 onches plus 3 feet 10 inches is 7.7 (by rounding)

Jaime is analyzing the exponential function y=19(0.91)^x. What is the growth or decay rate? Answer choices: A. 9% growth. B. 9% decay. C. 91% growth. D. 91% decay.
PS. I don't really understand this because this is new but can someone please find this as soon as possible <3. The x is an exponent.
Answer: Jaime is James
Step-by-step explanation: Remember that the original exponential formula was y = abx. You will notice that in these new growth and decay functions, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r). The growth "rate" (r) is determined as b = 1 + r.

Step-by-step explanation:
Janet enjoys reading books, and reads an average of 4 books a month. Janet's younger brother, Alex waited for a month before deciding he liked reading, and also reads at an average of 4 books a month. If m represents the number of months Janet has been reading books, the equation 4m=4(m−1) represents the situation where Alex and Janet have read the same number of books.
Solve the equation to find the number of months it will take for Alex and Janet to have read the same number of books. Show your work.
Answer:
No solution
Step-by-step explanation:
4m = 4(m - 1)
Distribute;
4m = 4m - 4
Subtract 4m from both sides;
0 ≠ -4
No months because Alex cannot catch up to Janet since they both read the same amount of books per month.
Answer: They will never have read the same number of books
Step-by-step explanation:
4(m-1) will always be less than 4m no matter what.

What is the x -intercept of x+4y=7?
Answer:
I believe it is (7, 0)
Step-by-step explanation:
I hope this is right..
Answer:
use slope intercept form to find the x intercept
y = Mx +b
Step-by-step explanation:
x+4y=7
4y= -x+7
y= -1/4x +7/4
so when this line is on the x intercept.. then y =0 soooo plug in zero for y and solve
0= -1/4x + 7/4
-7/4 = -1/4x
7 = x

A restaurant recorded what items from the kids menu were ordered on Friday night. Twenty-eight of the 76 kids at the restaurant Friday night ordered chicken nuggets. What is the ratio of kids who did not order chicken nuggets to the number of kids who did? Write your ratio in simplest form.
Answer:
12:7
Step-by-step explanation:
Total number of kids = 76
Total number of kids that ordered chicken nuggets = 28
Total number of kids that did not order chicken nuggets = 76 - 28
= 48
The ratio of kids who did not order chicken nuggets to the number of kids who did is:
= 48 : 28
In simplest form :
= 12:7
