The common factors are 2,4,5,10,20
This is under point slope intercept. so Ax+Bx=Cx. you can always change this to slope intercept which will be -.6y=.2x+.12 then give 1 a variable like 1 or 2 or something. then solve it, -.6y=.2+.12, -.6y=.32, y=-.53 so when x is 1, y is -.53. then make x 2 so -.6y=.52 so then when x is 2 y is -.86
Answer:
x = -13/9
Step-by-step explanation:
Solve for x over the real numbers:
8^(x - 3) = 16^(3 x + 1)
Hint: | Take logarithms of both sides to turn products into sums and powers into products.
Take the natural logarithm of both sides and use the identity log(a^b) = b log(a):
3 log(2) (x - 3) = 4 log(2) (3 x + 1)
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides by log(2):
3 (x - 3) = 4 (3 x + 1)
Hint: | Write the linear polynomial on the left hand side in standard form.
Expand out terms of the left hand side:
3 x - 9 = 4 (3 x + 1)
Hint: | Write the linear polynomial on the right hand side in standard form.
Expand out terms of the right hand side:
3 x - 9 = 12 x + 4
Hint: | Isolate x to the left hand side.
Subtract 12 x - 9 from both sides:
-9 x = 13
Hint: | Solve for x.
Divide both sides by -9:
Answer: x = -13/9
So i just finished this lesson. I am taking Algebra 1.
All you need to do is determine which number is X, and which number is Y. The formula is Y2-Y1 over X2-X1. Here is an example. And then make sure you simplify it to simplest form.
Width would have to be a quadratic
Use long division to find the other factor of the cubic polynomial P (x).
P (x) factors in case it is reducible over R[x]
if it weren't then P (x) mod R [x] would be a field
otherwise you could use the Eisenstein Criterion.
