3(K-2)=15
How do I solve for K

k = 7

Step-by-step explanation: Start by distributing the 3 through the parentheses on the left side of the equation.

3(k) is 3k and 3(-2) is -6.

So we have 3k - 6 = 15.

Next, isolate the k term by adding 6 to both

sides of the equation and we get 3k = 21.  

Now divide both sides by 3 and k = 7.

If you want, you can check your answer by plugging a 7

back into the original equation to see if it works.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
