Answer:x=6
Step-by-step explanation:Step-1 : Multiply the coefficient of the first term by the constant 1 • 18 = 18
Step-2 : Find two factors of 18 whose sum equals the coefficient of the middle term, which is -9 .
-18 + -1 = -19
-9 + -2 = -11
-6 + -3 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and -3
x2 - 6x - 3x - 18
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-6)
Add up the last 2 terms, pulling out common factors :
3 • (x-6)
Step-5 : Add up the four terms of step 4 :
(x-3) • (x-6)
Which is the desired factorization
Answer:
x = y
Step-by-step explanation:
x/3 + x/6 = 7/2
2x + x = 21
3x = 21
(divide 3 on both sides)
x = 7
Hello!
The problem has asked that we write a
point-slope
equation of the line in the image above.
Point-Slope Form uses the following formula:
y –
![y_{1}](https://tex.z-dn.net/?f=%20y_%7B1%7D%20)
= m(x –
![x_{1}](https://tex.z-dn.net/?f=%20x_%7B1%7D%20)
)
In this case, M represents the
slope while
![X_{1}](https://tex.z-dn.net/?f=%20X_%7B1%7D%20)
and
![Y_{1}](https://tex.z-dn.net/?f=%20Y_%7B1%7D%20)
represent the
corresponding X and Y values of any given point on the line.
We are given that the slope of the line is -
![\frac{5}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B7%7D%20)
. We also know that any given point on a graph takes the form (x,y). Based on the single point provided in the image above, we can determine that
![X_{1}](https://tex.z-dn.net/?f=X_%7B1%7D%20)
is equal to
6 and
![Y_{1}](https://tex.z-dn.net/?f=Y_%7B1%7D%20)
is equal to
2. Now insert all known values into the point-slope formula above:
y – 2 = -
![\frac{5}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B7%7D%20)
(x – 6)
We have now successfully created an equation based on the information given in the problem above. Looking at the four possible options, we can now come to the conclusion that
the answer is C.
I hope this helps!
we have the factors 2 x 2 x 3 x 5 x 7 = 420. It can also be written in exponential form as 22 x 31 x 51 x 71.
