That's a question that can't be answered here.
I know how to do algebra, and I could write how to do it for you. But If I start writing and keep going until I explain to you how to do algebra, do you know what you'd have here ? You'd have an algebra book, just like the one you use in school.
If it were possible to explain algebra in a few paragraphs, or even in a few pages, then that's what you would use in school to learn it, instead of a book. And if it could be explained in a few minutes, or even in a few hours, then teacher would explain it all at the beginning of the year, and then you'd have the rest of the whole year to just practice it and get really good at it.
You use a book, and you spend a whole year learning it, because that's what it takes.
I shall now reveal to you the secret hidden sneaky tricks of how to do algebra:
(If you want to print this and stick it on the refrigerator, you have my full permission.
This method is so good that it even works with a lot of other subjects too.)
-- Go to class every day.
-- As you're sitting down, turn off your cellphone and wrap up your gum.
-- Stay awake in class.
-- Listen to what the teacher is saying. In your mind, make pictures of what it means.
-- When you get a homework assignment, <em>write it down</em>.
-- Make a place at home where you always do your homework. Make it a place where other people aren't running through. While you're there doing homework, turn off the radio and your cellphone, and take the buds out of your ears.
-- <em>On the same day</em> you get the homework assignment, when you're home, sit down in the place where you do your homework, and work ALL of the examples in the assignment. (That may mean that you can't go out that night.)
-- If there's something you just don't get, ask the teacher for a time to sit down together and work on it together until you understand it. That's part of the teacher's job.
If you're building a brick house, and you leave out some bricks near the bottom and keep stacking bricks above the hole, the part above the hole could come crashing down any minute, and there's no way to go back later and try and fill in the hole.
Algebra is exactly like that. Each day or two, in class and in homework, you have to use what you learned in the<em> <u>last</u></em> day or two. If there's a hole there, it's awfully tough to build anything on top of it. If you don't understand how to do something, or you blow off a couple of homeworks, there is <em>no way</em> to go back and catch up <em>later</em>.
Follow my method, and algebra is <em>easy</em> !
Answer:
x = 17.51
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp/ adj
tan 35 = x/25
25 tan 35 =x
x=17.50518
Answer:
For mean
To show the mean of height measures for 40 students, you need to write-out exactly 40 heights into a calculator and add them up.
Then divide that total number by 40.
Step-by-step explanation:
Eg for 4 students
5 , 5.1, 5.2, 5.7 = 21ft
21/4 = 5.25ft.
Apply the same method but use 40 measures in addition for calulator or long addition. Then divide by 40.
Answer: C) 0.833%
Step-by-step explanation:
Given: Cost price of house = $120,000
The rate of increase of its cost = 10%
Therefore, the increase amount of house per year =10% of $120,000
Now, the amount increase each month=
Let r be the rate of growth each month, then
r% of $120,000=1000
f (x) = (1 / (x-2)) + 1g (x) = (1 / (x + 5)) + 9
Transformation of functions:
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
Suppose that h> 0
To graph y = f (x-h), move the graph of h units to the right.
To graph y = f (x + h), move the graph of h units to the left.
f (x) = (1 / (x-2)) + 1
To graph y = f (x) + k, move the graph of k units up.
h (x) = (1 / (x-2)) + 1 + 8
To graph y = f (x + h), move the graph of h units to the left.
g (x) = (1 / (x-2 + 7)) + 1 + 8
g (x) = (1 / (x + 5)) + 9
Answer:
The graph shifts 7 units left and 8 units up.
