Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to Start Fraction 7 over 25 End Fraction. She writes the equation y = x + Start Fraction 7 over 25 End Fraction. What error is Roni making?
A. She should have written y = negative x + StartFraction 7 over 25 EndFraction so that x and y have a constant sum.
B. She should have written x y = StartFraction 7 over 25 EndFraction so that x and y have a constant product.
C. She should have written y = StartFraction 7 over 25 EndFraction x so that x and y have a constant quotient.
D. She should have written y = StartFraction 7 over 25 EndFraction so that y has a constant value.

Which of the statements is true?
A. For every value of x, the rate of change of f(x) exceeds the rate of change of g(x).
B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).
C. At approximately x = 4.74, the rate of change of g(x) is equal to the rate of change of f(x).
D. As x increases, the rate of change of f(x) exceeds the rate of change of g(x).
A statement that is true include the following: B. As x increases, the rate of change of g(x) exceeds the rate of change of f(x).
How to determine the average rate of change?In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:
Average rate of change = [f(b) - f(a)]/(b - a)
Next, we would determine the average rate of change of the function f(x) over the interval [0, 1]:
a = 0; f(a) = 1
b = 1; f(b) = 6
By substituting the given parameters into the average rate of change formula, we have the following;
Average rate of change = (6 - 1)/(1 - 0)
Average rate of change = 5/1
Average rate of change = 5
For g(x), we have the following:
Average rate of change = (216 - 0)/(1 - 0)
Average rate of change = 216/1
Average rate of change = 216

Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x
Answer:
y = 2x - 1
Step-by-step explanation:
y = 2x - 1 wouldn't be a proportional relationship. You can tell because any equation with addition or subtraction is not going to be proportional.
Answer:
y=2x-1
Step-by-step explanation:
notice how the second option, y=2x-1 is the only option that has a constant. All other options only have a coefficient on the x term. This makes it perfectly proportional by the factor of the coefficient.

Evan worked 9 hours and
made $85.50. Henry worked 6 hours and made $57.00. Are
these two rates proportional?
Answer:
yes both of them make 9.5 the hour I know this because 85.50 divided by 9 is 9.5 9 times 9 is 81 and .5 times 9 is 4.5 so 81+4.5=85.5 and then 57 divided by 6 is 9.5 as well you can do 6 times 9 and you get 54 and then 6 times 0.5 is 3 and 54+3=57

Simplify the expression by arranging the steps in sequence, based on the order of operations. 1/6(30x+24)-1/7(63-7x)
Answer:
[tex]\frac{42}{42}[/tex] * (6x-5)
Step-by-step explanation:
Factor out 1/42 from both fractions first:
=
1/42 * (7(30x+24) - 6(63-7x))
then distribute the multiplication and combine like terms:
= 1/42 * (210x + 168 - 378 +42x)
= 1/42 * (252x-210)
Factor:
= 1/42 * 42(6x-5)
= 42/42 * (6x-5)
Which equation is NOT equivalent to 5 + n = 10. Select all that apply.
5 + n -n = 10 – n
5 + n – 5 = 10 - 10
5 + n – 5 = 10 - 5
5 + n + 3 = 10 + 3
5 + n – 10 = 10 - 5
Answer:
5 + n - 5 = 10 - 10
Step-by-step explanation:
if you do 5-5 that would equal zero, and if you do 10-10 it would equal 0 also, so all you would be left with is 0 + n= 0 and that is not equal to 5 + n = 10
Answer:
5 + n - 5 = 10 - 10

Which of the following values for x is true for 4x > 10
x = 34
x = 2
x = 2.5
x = 3
help!
Answer:
2.5
Step-by-step explanation:
its just 4 x x so you just times 2.5 by 4
Answer:
you can put 34 or 3 your choice!
Step-by-step explanation:
Ok so how you would find this out is first you put 4(x)>10
and you'll swap out the x for each number choice and 2.5 is the one that fits...
4(34)>10 = 136>10 yes
4(2)>10 = 8>10 well no bc 8 is less than 10
4(2.5)>10 = 10 = 10 not 10>10 so no
4(3)>10 = 12>10 yes

Find the sales tax.
Please also show your work so I can understand it :)
Answer:
Sales tax: 3.5$
Total Price: 73.5$
Step-by-step explanation:
the percentage of tax is that much of the total price. if there is 50% sales tax (unrealistic) and the item costs 100 dollars without any tax, then the tax would be 50 dollars. To find this, turn the percent into a decimal (move the decimal place to the left twice) and multiply that by the price. To do this with this problem, use this strategy. 70 times .05= 3.5. Therefore the tax is 3.5$. hope this helps!!

3.Ashley sees a book bag on sale in a store for $22. This is 20% off the original price. What was the original price of the book bag?
NUMBER 1
If 18 people is 40% that means the we need to start taking 40% off of numbers
40% of 20 is 12
40% of 25 is 15
40% of 30 is 18
So the answer is 30
NUMBER 2
If 21,000 people is 60% that means 20% is 7,000 people and 7,000x5=35,000 so there is a total of 35,000 people at the game
NUMBER 3
You should start taking 20% off of numbers.
20% of 25 is 20 too low so we need to go higher
20% of 26 is 20.8 still too low so lets keep going
20% of 27 is 21.60 closer but too low
20% of 28 is 22.40 which is too high lets go back since 27 is too low and 28 is too high lets start in between
20% of 27.5 is 22.00
So the answer is $27.5.

Step-by-step explanation:
If Albert Enstein has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are out and he is completely in the dark. How many socks must he take out to make 100 percent certain he has at least one pair of black socks?
Answer:
6 socks
Step-by-step explanation:
What we must do is calculate the probability of this happening, that he takes out two black socks in the first two taken out.
There are 12 black socks and in total they are 24, therefore the probability of drawing 1 is:
12/24
and now the probability of getting another one is 11 (there is one less outside) and in total they are 23:
11/23
the final probability is the multiplication of these events:
(12/24) * (11/23)
P = 0.24
Now, to know how many you should get, we multiply the probability by the total number of socks, that is:
0.24 * 24 = 5.76
So you must take out at least 6 socks for the above to happen.
the number of socks Albert Enstein has to take out to be sure that he has at least one pair of black socks is 38.
In order to determine the number of socks Albert Enstein has to take out to be sure that he has at least one pair of black socks, we would have to add the number of blue socks with the number of red socks.
Number of socks to be taken out = number of blue socks + number of red socks
21 + 17 = 38 socks
