You need to get K by itself and to do that do the opposite of -9 which is +9 and do the +9 to the -3 and positive 9 plus negative 3 is 6 so it it positive 6.
K=6

What is the solution of the following system? Use the substitution method.

Tatiana [17]

Answer:

y-2x=8 (label equation 1)

16+4x=2y (label equation 2)

divide equation 2 by 2 to find y

y=2x+8

sub this in equation 1

(2x+8)-2x=8

2x+8-2x=8

8=8

once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

Answer:

$f^{-1}(x)=4x+20$

Step-by-step explanation:

Given

$f(x)=\frac{x}{4}-5\\ \\y=\frac{x}{4}-5$

Swap x and y and solve for y

$y=\frac{x}{4}-5\\ \\x=\frac{y}{4}-5\\ \\x+5=\frac{y}{4}\\ \\4(x+5)=y\\\\y=4x+20$

Final answer

$f^{-1}(x)=4x+20$

Keep in mind that we need to swap the variables because a function and its inverse are symmetrical about the line y=x. See the graph below.

Robert is putting new roofing shingles on his house. Each shingle is 1 2/3 feet long. The north part of the house has a roof lin

Mariana [72]

Answer: 36 shingles can be placed on the north part of the house.

Step-by-step explanation:

Given: Length of each shingle = $1\dfrac23$ feet = $\dfrac53$ feet.

The north part of the house has a roof line that is 60 feet across.

Then, the number of shingles can be placed on the north part of the house = (Length of roof line in north part) ÷ (Length of each shingle)

$=60\div \dfrac{5}{3}\\\\=60\times\dfrac{3}{5}\\\\=12\times3=36$

Hence, 36 shingles can be placed on the north part of the house.
