The perimeter of the blueprint is represented by the equation P=8x. What is the equation of the perimeter when solved for x
Korvikt [17]

Answer:

x = P/8

The perimeter of the blueprint is given by the equation :

P = 8x

We need to solve the above equation for x.

Dividing both sides of the equation by 8.

\dfrac{P}{8}=\dfrac{8x}{8}\\\\x=\dfrac{P}{8}

Maria compared the slope of the function f(x)=(-6x-21) to the slope of the linear function that fits the values in the table bel
raketka [301]

Answer:

b. both functions have a negative slope

Step-by-step explanation:

The given function is

f(x)=-6x-21


This function is of the form y=mx+b, where m=-6 is the slope and b=-21 is the y-intercept.


We can also determine the slope of the function in the table using any two points, say (0,7)\:and\:(2,6).


The slope formula is given by,

m=\frac{y_2-y_1}{x_2-x_1}.


If (x_1,y_1)=(0,7)\:and\:(x_2,y_2)=(2,6), then,

m=\frac{6-7}{2-0}


m=-\frac{1}{2}.


We can see that both functions have a negative slope.


The correct answer is B.
