Pangolin,

You have not explained how you got the point A.

Remember, no trig is allowed.

102/2*

a14-a1 is 91, so the next term will always be 91/(14-1) more than the last, or 7 more.

a) a rule would be a(x)=6+7(x-1)

b) If we use the x axis as the a-number, we get that for every time we move over 1 x, the y increases by 7. This leads to a slope of 7. so we have y=7x+b. Plugging in the above examples a1=6 and a14=97, we get that the full equation should be y=7x-1.

c)The slope is how much the amount changes each time the a-number is increased by one. The y-intercept is the 0th number,-1.

d) using our rule, 6+7*27 is 6+189 or 195.

f is the function and n is the number that the function is being applied to

so if n were 2, since it is even you would do 2/2 to get 1

I agree! I think that if you use someone elses work you should post the link to the original answer and give full credit to the original answerer. It  is definitely not right to plagarize or take credit for other peoples answers like DewdropDancer said before.....

We write the complex numbers in exponential form:

(2*e^(pi*i/8))^8 + (2*e^(-pi*i/8))^8 = 256*e^(pi*i) + 256*e^(-pi*i) = -512.

Correct!!!

First line rearranged 

y= 

-2/3 x + 7/3

slope = - 2/3       Perpendicular slope = - 1 / (-2/3) = m = 3/2

So the car travels 20+25+(60*45/60)+(48*(15/60) kilometers, or 20+25+45+12=102 kilometers.

Going at 40kph in one hour would get you 40 kilometers, so half of that time is needed for 20 kilometers. Same for the 50kph for 25 kilometers.

30+30+45+15 is 120. But our answer has to be in kilometers per hour, minutes would not work. So 120/60 is 2.

92/2 is an average of 51 Kph

1. First convert from standard form to slope intercept form .

$5x+8y=-9$

$8y=-5x-9$

$y=-5/8-9/8$

$m=-5/8$

2. find other line

Perpendicular lines have negative reciprocal slopes

$-5/8 =>8/5$

$y=8/5x+b$

From the given information, 

$(10)=8/5(10) + b$

$10=16+b$

$b=-6$

the line is:

$y=8/5x-6$
therefore 8/5-6=$-22/5$

Total distance = 20 + 25 + 45 + 12 = ..... km

Total time = .5 hr + .5 hr + .75 hr + .25 hr = .......... hrs

avg speed = (total distance) / ( total time )  =   ........   km/ hr

I just graphed it

But you can also find the values of the x and y-intercepts

To find the y-intercept, x has to be 0, 0-1 is -1, and -1^2 is 1. 0+3 is 3, and 3*1 is 3. So the y-intercept would be (0,3)

To find the x-intercepts, y has to be zero. So either (x+3) or (x-1)^2 should be 0.

For (x+3), to make it 0, x has to be -3.

Since squaring any number except 0 can't get you zero, the square doesn't matter. So x-1 is 0. x=1. So our x-intercepts are (-3,0) and (1,0).

The base has length 4 and the triangle has a height of 3. (4*3)/2 is 6.

(6, 24, 42, 66, 222, 246, 264, 426, 444, 462, 624, 642, 666)>>Total = 13 such numbers.

We can use long division

 I got 4x+9 but I'm not sure

i suggest you search up polynomial division, there are some great tutorials like khan academy that are free

3y + 59 + (180-140)  = 180

y= 27 degrees

y + 59 + a  = 180

a=94

180-94  +y  +x =180

x=67 degrees

Could you put the question more clearer? It doesn't exactly make sense.

-9/6 / 3/-2    =  -9/6 * -2/3  = 18/18 =1

The process is really tedious but here is my answer(it might not be right)

 8(15 - m)

[I Tried to be as neat as I could]

Let

x = the number of multiple choice question

y = the number of free response question

we know that

 3x + 8y = 55 = Equation A

x+y=15

x = 15 - y = Equation B

Substitute equation B in equation A

3[15-y] + 8y = 55

45 - 3y+ 8y = 55

5y = 55 - 45

5y = 10

y = 2

Find the value of x

x = 15 -  y

x = 15-2= 13

therefore

the answer is

the number of multiple choice question are 13

the number of free response question are 2

All right, this is getting ridiculous. Melody and I have told you many times to not copy others' answers. This time you copied CPhill's. We both know very well that plagarism is bad, so just put a link...

Here is CPhill's answer: https://web2.0calc.com/questions/help-fast-please_4

is it this question?

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question. There are 15 questions on the test and the students have been given 55 minutes to complete it.

Because i've heard of this before.

The question sort-of gets cut off at "There are 15"
