Let's recall the equation to find out the slope of a line:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Next, we substitute our given values into the equation, and simplify:

\frac{9-7}{6-3}=\frac{2}{3}

Now, we insert the slope (2/3) into the y=mx+b equation and substitute the values from one of the coordinates to find what b, the y-intercept is:

y=\frac{2}{3}x+c \\ 7=\frac{2}{3}(3)+c \\ 7=2+c \\ c=5

So, the y-intercept is 5. We can now put our discovered values for the slope and the y-intercept into one equation:

y=\frac{2}{3}x+5

The answer is B.

What is the length and width of a room that is 60 square meters and has a perimeter of 32 meters
AleksAgata [21]
L = lenght
W = width

L * W = 60 \\
2L + 2W=32\\\\
L = \frac{32-2W}{2}\\
\frac{32-2W}{2}*W = 60\\
(16-W)*W = 60\\
-W^{2} + 16W -60 = 0\\\\

d = 16^{2} - 4*1*60 =  256 - 240 = 16 \\\\
W1 = \frac{-16+\sqrt{16}}{-2} =  \frac{-12}{-2} = 6\\
W2 = \frac{-16-\sqrt{16}}{-2} =  \frac{-20}{-2} = 10\\

L1 = 10\\
L2 = 6\\


so

{L,W} = {6,10} or {10,6}

but L > W  so

L = 10
W = 6

gladu [14]

Answer:

A=45000(0.82)^t

Step-by-step explanation:

Given data

P= 45,000

rate= 18%

Recall the expression for the compound interest

A=P(1+r)^t

Since we are talking of depreciation

A=P(1-r)^t

Substitute

A=45000(1-0.18)^t\\\\A=45000(0.82)^t

Hence the exponential function is

A=45000(0.82)^t
