Answer:

7. 29 cm

8. equation: 61 = (x) +(2x -7) +(3x +2); sides 11, 15, 35

Step-by-step explanation:

7. Let w represent the width. The length is 3 less than twice the width, so the length is 2w-3. The perimeter is given by the formula ...

P = 2(L+W)

Substituting the known values, we have ...

90 = 2((2w-3) +w)

45 = 3w -3 . . . . . . . . divide by 2

15 = w - 1 . . . . . . . . . .divide by 3

16 = w . . . . . . . . . . . . add 1

L = 2w -3 = 2(16) -3 = 29

The length of the rectangle is 29 cm.

__

8. The equation that should be used is the one that relates the side lengths to the perimeter.

P = a + b + c . . . . for sides a, b, c

61 = (x) +(2x -7) +(3x +2)

61 = 6x -5 . . . . . . collect terms

66 = 6x . . . . . . . . add 5

11 = x . . . . . . . . . . divide by 6

Then the side lengths are ...

a = x = 11

b = 2x -7 = 2(11) -7 = 15

c = 3x +2 = 3(11) +2 = 35

<em>Comment on problem 8</em>

You will notice that the side lengths do not satisfy the triangle inequality: the sum of the short sides is not greater than the long side. <em>These side lengths cannot form a triangle</em>. Cute algebra, but <em>bad geometry</em>.

In the graph shown below, what is f(2)?

ira [324]

The answer is A. f(2) = 2

We are looking for where the line is expressed when x = 2. A closed dot allows us to know that point is included. An open dot is not included, although the line approaches it, infinitely closely.

Dominique needs to solve the system of equations by graphing. Which statement is true about the system? 2 x minus 3 y = 12. Y =

Nutka1998 [239]

Answer:

Option C) The first equation is y= 2/3x-4 when written in slope-intercept form .

Step-by-step explanation:

We have

$2x - 3y = 12 \: > \: first \: equation$

The first equation is in Standard form .

Convert to slope Intercept form .

Isolate the Variable y .

$3y = 2x - 12$

Divide by 3 both sides .

$y = \frac{2}{3} x - 4$

$y = - \frac{3}{5} x + 2 > second \: equation$

The second equation is in slope Intercept form .

Convert to standard form

Multiply by 5 both sides to remove the fraction .

$5y = - 3x + 10$

$3x + 5y = 10$

<h3><u>Verify each statement :- </u></h3>

<h3>• case A) Both equations are in slope-intercept form.</h3>

False

Because only the second equation is in slope -intercept form

<h3>• case B) Neither equation is in slope-intercept form .</h3>

False

Because, the second equation is in slope -intercept form

<h3>• case C) The first equation is y= 2/3x-4 when written in slope-intercept form</h3>

True (see the procedure)

<h3>• case D)The second equation is 3x+5y=10 when written in slope-intercept form.</h3>

False

Because, the second equation is 3x+5y=10 when written in standard form .
