The answer to <span>-7(k+9)=9(k-5)-14k is 
k = -9


</span>-7(k+9)=9(k-5)-14k
Use the distributive property to distribute the -7 to (k+9) and 9 to (k-5)
-7(k+9)=9(k-5)-14k
-7k - 63 = 9k - 45 - 14k
Now lets get all our constants on one side of the equal sign and all our terms such as 9k and 4k on a side by their self
-7k - 63 = 9k - 45 - 14k
-7k - 63 + 45 = 9k - 45 + 45 - 14k
-7k - 18 = 9k - 14k
Now lets get that -7k on the right side
-7k + 7k - 18 = 9k - 14k + 7k
-18 = 9k - 14k + 7k
Now lets do the math for 9k - 14k + 7k and solve for k
-18 = 9k - 14k + 7k
-18 = 2k
-18 / 2 = 2k / 2
-9 = k
k = -9

Which of the following function rules will translate all of the coordinates of a function f(x,y) to the right 2 units and five u
algol [13]

Answer: 4. (x+2, y-5)

Step-by-step explanation:

Translation is a right motion used to move a figure on coordinate plane by some distance.

The translation rule to translate a image h units right and k units down is given by :-

(x,y)\to (x+h, x-k)

So, the translation rule for translating all of the coordinates of a function f(x,y) to the right 2 units and five units down will be

(x,y)\to  (x+2, y-5)

Hence, the correct option is 4. (x+2, y-5).

Step-by-step explanation:

Point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y--3 = 4 (x--1)

y+3 = 4(x+1)

Please help me with this problem
Juli2301 [7.4K]
The volume is 5x3x9= 135inches
surface area= surface area is 174 because
3x9= (27x2)=54
5x9=(45x2) =90
3x5= (15x2) =30
 so 54+90+30 is 174
because you have to find the area of each face, and then plus them together 
hope this helped
