if you cant see the numbers on the chart they are.....
N 1 2 3 4 5
f(n) 155 141 127 113 99
Answers
Answer:
-14
Step-by-step explanation:
Start at 99 (5th number) and keep subtracting 14 until you get down to the 15th number. Then once you keep subtracting you will get -14. But there are negative numbers after the 12th number. So you might have to deal with those... but overall you got it! <3

Which answer choice represents an equivalent number sentence of "49 - 12"?
A. 37
B. 49 + (-12)
C. 49 + 12
D. 12 - 49
Answers
Answer:
B
Step-by-step explanation:
A. 37 isn't a number sentence
B. 49 + (-12) = 49-12. They're the same thing because 49 minus 12 can also be written as 49 plus negative 12
C. 49 + 12 doesn't equal 49-12
D. 12- 49 = -37 which isn't equivalent to 49-12.
Hope this helps!!!
HELP DUE AT 11:59!!!!!
1.Write the arithmetic sequences that would find the nth term.
2.Using the formula you created, what is the 15th term?
Answers
Answer:
f(n) = 155 - 14(n-1) [Question 1, Arithmetic sequence]
f(15) = -41 [Question 2, 15th term]
Step-by-step explanation:
Given the explicit formula for an arithmetic sequence: f(n) = f(1) + d(n-1).
Where d is the common difference, f(n) is the nth term, and f(1) is the first term.
Given that the first term f(1) is 155 from the table since 1 is n, and 155 is f(n). And the second term f(2) is 141 since n is 2, and 141 is under f(n) on the table when n is 2.
Subtract the two terms to find the common difference: d = f(2) - f(1) = f(3) - f(2) = f(4) - f(3) = ...
d is 155-141= -14.
Remember how the first term in the sequence is 155, and how d is -14, we can make this into an equation:
f(n) = f(1) + d(n-1) → f(n) = 155 - 14(n-1).
We can test this by matching the equation by input, and output to the table:
f(1) = 155 - 14(1-1) = 155
f(2) = 155 - 14(2-1) = 155 - 14 = 141
f(3) = 155 - 14(3-1) = 155 - 28 = 127
f(4) = 155 - 14(4-1) = 155 - 42 = 113
f(5) = 155 - 14(5-1) = 155 - 56 = 99
......
f(15) = 155 - 14(15-1) = 155 - 196 = -41

Answer:
[tex]m=8x-5-4\Delta x[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=4x^2-5x-1[/tex]
And we want to use the difference quotient:
[tex]m=\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]
To find the slope function.
So, let's substitute [tex]x+\Delta x[/tex] for our function. This yields:
[tex]m=\frac{(4(x+\Delta x)^2-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]
Let's square. Use the perfect square trinomial pattern. This yields:
[tex]m=\frac{(4(x^2+2x\Delta x-\Delta x^2)-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]
Distribute:
[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)-(4x^2-5x-1)}{\Delta x}[/tex]
Distribute the right:
[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)+(-4x^2+5x+1)}{\Delta x}[/tex]
Combine like terms:
[tex]m=\frac{(4x^2-4x^2)+(-5x+5x)+(1-1)+(8x\Delta x-4\Delta x^2-5\Delta x)}{\Delta x}[/tex]
The first three terms will cancel. This leaves us with:
[tex]m=\frac{8x\Delta x-4\Delta x^2-5\Delta x}{\Delta x}[/tex]
We can factor out a Δx from the numerator:
[tex]m=\frac{\Delta x(8x-4\Delta x-5)}{\Delta x}[/tex]
The Δx will cancel. So, our slope function is:
[tex]m=8x-5-4\Delta x[/tex]
And we're done!

Step by Step Explanation:
To solve this equation, we do NOT need the same denominator.
And since both fractions are negative, we know the answer is going to be positive.
So we just multiply normally.
-1/4 • -3/7
We cannot cross cancel anything, so we just multiply across.
-1 • -3 = 3
-4 • -7 = 28
So our answer is 3/28.

Answer:
Step-by-step explanation:
Move the decimal point in the divisor and dividend.
Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.
Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.
Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.
Line up each digit in the quotient just over the last digit in the dividend used in that cycle.

Kristen paid $39 for 60 cans of corn. How much did she pay per can?
Answers
Answer:
.60 per can
Step-by-step explanation:
39 dollars divided by 60 cans
The ratio of the amount of money that Kristen paid to the number of cans gives the amount per can thus it will be $0.6 per can.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
Kristen paid $39 for 60 cans of corn.
Ratio of the amount to the number of cans,
39/60 = $0.6 per can
Hence "The ratio of the amount of money that Kristen paid to the number of cans gives the amount per can thus it will be $0.6 per can".
