### What is the slope of the line whose equation is -48 2x-8y?

In order to find the slope, you need to get y by itself.
Follow the equation: y = mx + b
m = slope
-48 = 2x - 8y
Subtract 2x from both sides of the equation.
-2x - 48 = (2x - 2x) - 8y
(I find it easier to have y first in the equation, but either
way is fine.)
-8y = -2x - 48
Divide every number by -8.
-8y/-8 = (-2x/-8) + (-48/-8)
y = 1/4x + 6
y = mx + b
m = 1/4

### What are the roots when thequadratic equation 2x-48-x2?

You gave a quadratic expression, not equation. Assuming you
mean:
2x - 48 - x^2 = 0
Rearrange into standard form ax^2 + bx + c = 0:
-x^2 + 2x - 48 =0
You could directly apply the quadratic formula with a = -1, b =
2, c = -48; or you could multiply by -1 first, giving:
x^2 - 2x + 48 = 0
Then a = 1, b = -2, c = 48; it turns out that there are no real
roots -- it has only complex roots, which are:
x = (1 + i√47) and (1 - i√47)

###### Asked in Factoring and Multiples

### What is the factorization of the trinomia -x2 plus 2x plus 48?

The expression is -x² + 2x + 48.
Factor out -1 to get:
-(x² - 2x - 48)
Find two integers such that the product is -48 and the sum is
-2. They are -8 and 6. Then, we can rewrite the expression as:
-(x² - 8x + 6x - 48)
Factoring-by-grouping, we obtain:
-(x(x - 8) + 6(x - 8))
= -(x + 6)(x - 8) [Collect x and 6 and group x - 8.]

###### Asked in Algebra

### What is x in algebra?

X is the most famous variable in algebra, and a variable is a
letter that stands for a number. It is used for you to apply
methods of problem solving to get the answer, and the answer will
be what x stands for. For example, if you see the problem
48-2x=100, you know you have to solve for x. The next step would be
to subtract 48 from both ends of the equation, so you get (48-2x)
-48= (100) -48 ---> -2x=52. Then you divide each side by -2 to
get x by itself ---> -2x/2=52/-2 ---> x= -26. So you can see
that x is not one specific number, it is just a variable.

### What is the factorization of the trinomial below. -x2 - 2x plus 48?

First, I'll multiply by -1, to make it a little easier to work
with (then when done, I'll multiply by -1 again): x2 + 2x - 48. We
want two numbers, when multiplied yield -48, and the sum is 2: -6
and 8. (x + 8)(x - 6) works. Now multiply one of the binomial
factors by -1: (x + 8)(6 - x). Multiply using FOIL to check:
-x2 - 2x + 48

###### Asked in Math and Arithmetic, Algebra, Calculus

### How do you solve 6 times x minus 8 equal 2x plus 12?

The question is a very difficult one to answer. So, rather than
describe how to solve
the equation, it'll be much easier and faster if we just go
ahead and solve it.
6 (x - 8) = 2x + 12
Clear parentheses on the lft side:
6x - 48 = 2x + 12
Subtract 2x from each side:
4x - 48 = 12
Add 48 to each side:
4x = 60
Divide each side by 4:
x = 15
