How do you factor the expression x cubed minus x squared?
x3-x2
Both terms in this expression have x2 in them, so "divide" each term by it using the distributive property in reverse.
x2(x-1) = x3-x2
If you "re-distribute" you should see that they are equal.
What is the value of x and y if 4x plus 1.5y equals 79?
There are infinitely many pairs of values (x, y) which will satisfy 4x + 1.5y = 79
The equation can be rearranged:
4x + 1.5y = 79
⇒ 1.5y = 79 - 4x
⇒ y = (158 - 8x) ÷ 3
For any given value of x, plug it into the above equation and the corresponding value of y will be calculated. So, some pairs of values (x, y) that satisfy this are:
(-2, 58), (1, 50), (4, 42), (7, 34)
How do you make x the subject of x squared-b equals 9?
x2-b = 9
x2 = 9+b
Square root both sides:
x = the square root of (9+b)
What is 2x-6x plus 5 equals 0?
2X - 6X + 5 = 0
subtract 5 from each side
2X - 6X = - 5
do what it says on the left
- 4X = - 5
X = 5/4
check in original equation
2(5/4) - 6(5/4) + 5 = 0
10/4 - 30/4 + 5 = 0
- 20/4 + 5 = 0
- 5 + 5 = 0
0 = 0
checks
What is 9x squared minus 6xy plus y squared minus 81 factored as?
9x2 - 6xy + y2 - 81
= (3x - y)2 - 92
= (3x - y - 9)(3x - y + 9)
What is the volme of 752m x 319m x 110m?
Don't you have a calculator? Just multiply them together. It's really simple and a whole lot faster than going to a website and make us do your homework for you.
What is e to the x times x squared?
It is an expression whose value will depend on the value of the variable x.
How do you find x in 8 equals -16x2 plus 30x plus 3.5?
ANYTIME. a number is next to a variable it means that number has to be multiplied by the variable. Try writing it out as 30 times x in the equation. Its quite simple just refere to the Order of operations and PEMDAS search around if you are not sure on how to find the value of a variable. Its actually quite simple. Since I infer you are probably doing homework I don't want to go ahead and give you the value so this is the most i can help you.
What is the sum of all function in any circle graphs?
THere are infinitely many possible functions in any circle graph. Your question needs to be more specific.
It would have been far simpler and quicker to use your calculator but since you are unable or unwilling to make that effort, the answer is 2.1
The clue is in the question inasmuch that there is no remainder so using the remainder theorem the result must equal zero:-
f(x) = x3+x2+xy+8
f(x) becomes f(1) because the divisor is x-1
f(1) = 13+12+1y+8 = 0 because ther's no remainder
f(1) = 1y = -10
So y = -10
