Two times the width of a certain rectangle exceeds its length by three inches, and eight times its length is twelve more than it

yan [13]

Perimeter is the sum of all sides of a shape. For a rectangle, it is the sum of the two lengths and two width measurements. We set up the equations as follows:

l = 2w - 3

P = 8l - 12

P = 2w + 2l
8l -12 = l - 3 + 2l
5l = 9
l = 9/5

9/5 = 2w - 3
w = 12/5

Arrange the equations in the correct sequence to rewrite the formula for displacement, , to find a. In the formula, d is displac

OverLord2011 [107]

Answer:

2(d-vt)=-at^2

a=2(d-vt)/t^2

at^2=2(d-vt)

Step-by-step explanation:

Arrange the equations in the correct sequence to rewrite the formula for displacement, d = vt—1/2at^2 to find a. In the formula, d is

displacement, v is final velocity, a is acceleration, and t is time.

Given the formula for calculating the displacement of a body as shown below;

d=vt - 1/2at^2

Where,

d = displacement

v = final velocity

a = acceleration

t = time

To make acceleration(a), the subject of the formula

Subtract vt from both sides of the equation

d=vt - 1/2at^2

d - vt=vt - vt - 1/2at^2

d - vt= -1/2at^2

2(d - vt) = -at^2

Divide both sides by t^2

2(d - vt) / t^2 = -at^2 / t^2

2(d - vt) / t^2 = -a

a= -2(d - vt) / t^2

a=2(vt - d) / t^2

2(vt-d)=at^2

need help to determine if it's a undefined slope or it is a slope of line and what's the answer please and thank you

ICE Princess25 [194]

Answer:

It is slope of a line which is 4

Step-by-step explanation:

We are given that the given points are generated by a linear function. A linear function is ta straight line that can be represented by:

$y = mx+b$

Here m is the slope

The slope of a line is given by the formula:

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

In order to find the slope from the table we take any two pairs of inputs and outputs i.e. x and y

So here we take

(x1,y1) = (-6,-16)

(x2,y2) = (-5,-12)

Putting the values in the formula

$m = \frac{-12-(-16)}{-5-(-6)}\\m = \frac{-12+16}{-5+6}\\m = \frac{4}{1}\\m = 4$

Hence,

It is slope of a line which is 4

Graph both functions to find the solution(s) to the system.

Sliva [168]

F(x) = -2x +1 ( slope = -2 y intecept is 1)

replace x with 0 and solve for y =-2(0)+1 = 1 ( 0,1)
replace x with 2 and solve for y: -2(2) +1 = -4+1 = -3 (2,-3)

plot those 2 coordinates and draw a line

this is the red line on the attached graph

do the same for the g(x) formula
