Answer:

x = $\frac{3}{2}$

Step-by-step explanation:

The figures are similar, thus the ratios of corresponding sides are equal, that is

$\frac{8}{3}$ = $\frac{4}{x}$ ( cross- multiply )

8x = 12 ( divide both sides by 8 )

x = $\frac{12}{8}$ = $\frac{3}{2}$ = 1.5

The length of a rectangle is twice its width.

shtirl [24]

Formula we use,

→ P = 2(L + W)

Then the value of L and W is,

→ P = 2(L + W)

→ 48 = 2(2x + x)

→ 2(3x) = 48

→ x = 48/6

→ [ x = 8 ]

Then the width will be,

→ W = x = 8 ft

Hence, the width is 8 ft.

Now the length will be,

→ L = 2x = 2(8) = 16 ft

Therefore, the length is 16 ft.

The answer should be 6! all you have to do is plug the numbers into the equation!
it would be like this:
-1^2+3^2+(-1)-3
doing all of that would equal 6!

Equation for ( 6, 13) ( 7900, 5 )

tia_tia [17]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

$y=mx+b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

$(x_ {1}, y_ {1}) :( 6,13)\\(x_ {2}, y_ {2}): (7900,5)$

We find the slope of the line:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {5-13} {7900-6} = \frac {-8} {7894} = - \frac {4} {3947}$

Thus, the equation of the line is of the form:

$y = - \frac {4} {3947} x + b$

We substitute one of the points and find b:

$13 = - \frac {4} {3947} (6) + b\\13 = - \frac {24} {3947} + b\\13+ \frac {24} {3947} = b\\b = \frac {51335} {3947}$

Finally, the equation is:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$

Answer:

$y = - \frac {4} {3947} x + \frac {51335} {3947}$
