Answer:
2*2*3*3*5
Step-by-step explanation:
180 = 18*10
18 and 10 are both composite
= 6*3 * 5*2
3,5,2 are prime but 6 is composite
= 3*2 * 3 * 5 * 2
All the factors are prime
Listing in order
2*2*3*3*5
U = -b + 21 . . . (1)
u = -2b + 30 . . . (2)
Equating (1) and (2),
-b + 21 = -2b + 30
-b + 2b = 30 - 21
b = 9
u = -9 + 21 = 12
Therefore, (b, u) = (9, 12).
We can't find explicit values for
and
, since there is only one equation, but two variables.
The best we can do is solve for one variable with respect to the other:
Solve for
:
subtract
from both sides:
![110-5y = 9x](https://tex.z-dn.net/?f=%20110-5y%20%3D%209x%20)
divide both sides by
:
![\frac{110-5y}{9} = x](https://tex.z-dn.net/?f=%20%5Cfrac%7B110-5y%7D%7B9%7D%20%3D%20x%20)
Solve for
:
subtract
from both sides:
![110-9x = 5y](https://tex.z-dn.net/?f=%20110-9x%20%3D%205y%20)
divide both sides by
:
![\frac{110-9x}{5} = y](https://tex.z-dn.net/?f=%20%5Cfrac%7B110-9x%7D%7B5%7D%20%3D%20y%20)
Answer:
D. y = 2x - 2
Step-by-step explanation:
1) First, find the slope of the given line. Place it in slope-intercept form to identify its slope easily. Isolate the y in the equation:
![2y-4x = 1\\2y = 4x+1\\y = 2x+\frac{1}{2}](https://tex.z-dn.net/?f=2y-4x%20%3D%201%5C%5C2y%20%3D%204x%2B1%5C%5Cy%20%3D%202x%2B%5Cfrac%7B1%7D%7B2%7D)
A line placed in slope-intercept form is represented by the formula
. The
, or the coefficient of the x-term, represents the slope. Thus, the slope of this line is 2.
2) Lines that are parallel share the same slope. So, the slope of the parallel line will have 2 as its slope as well.
We now have enough information to write the equation of the line in point-slope form. From there, we can convert it to slope-intercept form and find out which option is correct.
Use the point-slope formula
and substitute values for
,
, and
. Since
represents the slope of the line, substitute 2 in its place. Since
and
represent the x and y values of a point the line intersects, substitute the x and y values of (4,6) into the formula as well. Then, with the resulting equation, isolate y like before to find which option is correct:
![y-6 = 2(x-4)\\y-6 = 2x-8\\y = 2x-2](https://tex.z-dn.net/?f=y-6%20%3D%202%28x-4%29%5C%5Cy-6%20%3D%202x-8%5C%5Cy%20%3D%202x-2)
So, option D is correct.
I would assume b ^5 .. add 3 plus 2 and put it as the power or exponent whatever it’s called
