On the 28th day we have
22 + 5*( 28-1) = 22 + 5 * 27 = 157 people
Sum of the series, S, is
S = ( first term + last term) * number of terms / 2 =
( 22 + 157) * 28 / 2 =
179 * 14 =
2506 = total people
Add the first two equations and we get that
(a + 1) x + (a + 1) = 2
(a + 1) ( x + y) = 2
(a + 1) (6) = 2
(a + 1) = 2/6
a + 1 = 1/3
a = 1/3 - 1 = -2/3

y^4 - 2y^3 + 8y - 5
Rearrrange as
x^2 -10x + 4y^2 + 58y = k complete the square on x and y
x^2 -10x + 25 + 4( y^2 + (58/4)y + 841 / 16) = k + 25 + 841 / 4
factor and simplify
(x - 5)^2 + 4 (y + 27/4)^2 = k + 941/4
To be non-degenerate k + 941/4 must be greater than 0
So
k + 941/4 > 0
k > -941/4 = a
The expected number of times Bob rolls his die is 292.
1/2 distance + 1/2 of 1/2 distance = 3/4 driven soooo
1/4 remains = 5
total = 20 miles
Sub in the x, y points given and equate the equations
2*6 = B = 12
6 = A 22 + B B = 12 substitute this in
6 = A 4 + 12
A = - 6/4 = - 1.5
When multiplying x's with exponents , add the exponents
5 + x = 9
x = 4 degree
8 feet = 96 inches
3/4 foot = 9 inches
96 mod 9 = 6 inches left over
or 8 mod 3/4 = .5 ft left over = 6 inches
first strike 100 ft 1
then up and down to second strike = 50 x 2 = 100 2
then up and down 25 ea = 50 3
up and down 12.5 = 25 4
up and down 6.25 = 12.5 5
up 3.125 = 3.125 ft
Add the red numbers
120 paper /day * 7 days/week * .08 / paper = $ 67.20 /week
1 /8 * x = 1/2
x = 1/2 * 8/1 = 4 it will take four 1/8 cups to make a 1/2 cup
4 * 1/8 = 4/8 = 1/2
(2x^4+3x^3+x-14)(3x^{10}-9x^7+9x^4+30)-(x^2+5)^8
We only need to see that the highest degree polynomial resulting from the multiplication of the first two polynomials is 2x^4 * 3x^10 = 6x^14 = 14 th degree
The highest degree of the last poltnomial is - (x^2)^8 = -x^16 = 16
So....the degree of the resulting polynomial is 16
3(x - 4) - 2(x^2 - x + 7) - 5(x - 1)
The constant is 3(-4) - 2(7) - 5(-1) = -12 - 14 + 5 = -21
Well I emailed my teacher and she said
"You can also do 2.33 x 6.5. Which would give you 15.15 rounded to the hundredths place. I rounded 2.33 to the nearest tenths place to get my answer. 2.3 x 6.5 = that is how I came up 14.9"
Ok I will try
Positive.......
You shure????
Agree with catmg......your teacher doesn't sound very good.....
Catmg's area answer is exactly correct !!!!
Hey there, Guest!
Let's get right into it:
3/5x=33
1/5x=11
x=55
And there we have our answer.
Hope this helped! :)

If we draw a horizontal line at y = -1, it will only intersect the function at one point
So....only one value of "c"
2 1/3 does not equal 2.3
Please don't listen to your teacher.
2 1/3 = 2.3333333 (with infinite threes)
While you can estimate 2 1/3 as 2.3, it's not very accurate, especially if you're doing small scale things like this problem.

So Noah paid a total of $56 for a book and a CD player.
The equation would be this: 7x=$56
Then, we can simplify that to become x=$8
5x is the difference between the two.
So, 5*8= $40 is our answer.
Well my teacher said how she got the answer was I changed 6 1/2 to 6.5 and 2 1/3 to 2.3 then multiplied 6.5 x 2.3
if f(4) = 7.
f(4x) when x = 1 is also 7.
3*7 - 5 = y/2
16 = y/2
y = 32
So the poitn is (1, 32)
