7 0

<span>Hello : let A(-10,-3) B(7,14)
the slope is : (YB - YA)/(XB -XA)
(14+3)/17) = 1
an equation is : y=ax+b a is a slope</span>

y = x +b

the line F through point B(7,14) : 14 =7+b<span>
<span>b = 7
the equation is : y =X+7</span></span>

<span>the x- intercept of F when y=0 : x+7 =0 so : x = - 7 </span>

AB=AD. Enter the range of values for x. 40° 14° 9x-27 108. ?

zalisa [80]

The range of values of x as shown in the diagram is -9 < x < 15

<h3>Inequality expressions</h3>

Inequality are expressions not separated by an equal sign. The required inequality expression is given as:

|9x - 27| < 108

For the positive inequality

9x - 27 < 108

9x < 108 +27

9x < 135

x < 15

For the negative inequality

-9x + 27 < 108

-9x < 108 - 27

-9x < 91

x > -9

-9 < x

Hence the range of values of x as shown in the diagram is -9 < x < 15

The perimeter of a rectangle is 42 inches, and its area is 110 square inches. find the length and width of the rectangle.

lorasvet [3.4K]

$p = 2w + 2l$ $p = 42$
$a = l * w$ $a = 108$

You want to make either the length or width variable (I chose the width variable to be by itself. It doesn't matter) by itself by:

Divide both sides by 2.
(p) ÷ 2 = (2w + 2l) ÷ 2
$2's$ $cancel$ $out$
$\frac{p}{2} = w + l$

Subtract both sides by either length or width depending on what variable you chose to make by itself (in this case I subtracted the length variable because I wanted the width variable by itself).
$\frac{p}{2} - l = w + l - l$
$l's$ $cancel$ $out$
p/2 - l = w

$a = l * w$

You replace w with the equation above p/2 - l = w
$a = l( \frac{p}{2} - l)$

Multiply out the L.
$a = \frac{p}{2}l - l^{2}$

Plug in all your numbers a = 110 and p = 42
$110 = \frac{42}{2}l - l^{2}$
$110 = 21l - l^{2$

Move everything to the left side so $l^{2}$ would be positive (makes the equation easier when $l^{2}$ is positive).
$l^{2} - 21l + 110 = 0$

Factor.
$(l -10)(l-11) = 0$

Make each parenthesis set equal to 0.
$l-11=0$ $l-10=0$

Add.
$l = 11$ $l = 10$

By doing this you solve for both the width and length so the answer is:
w = 11 L = 10
