Answer:

undefined

Step-by-step explanation:

We can find the slope of a line using two points by

m = (y2-y1)/(x2-x1)

= (-9- -4)/(-4 - -4)

= (-9+4)/(-4+4)

= -5/0

When we divide by zero, our solutions is undefined

The slope is undefined

the frame of a picture is 28 cm by 32 cm outside and is of uniform width.What is the width of the frame if 192 cm2 of the pictur

natita [175]

Answer:

The width of the frame is equal to $8\ cm$

Step-by-step explanation:

Let

x-------> the width of the frame picture

we know that

$(28-2x)(32-2x)=192$

$896-56x-64x+4x^{2} =192$

$4x^{2}-120x+704=0$

Simplify

$x^{2}-30x+176=0$

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-30x+176=0$

$a=1\\b=-30\\c=176$

substitute in the formula

$x=\frac{30(+/-)\sqrt{(-30)^{2}-4(1)(176)}} {2(1)}$

$x=\frac{30(+/-)\sqrt{196}} {2}$

$x=\frac{30(+/-)14} {2}$

$x=\frac{30+14} {2}=22\ cm$ ----> this solution is not logic

$x=\frac{30-14} {2}=8\ cm$

The width of the frame is equal to $8\ cm$

Lena [83]

Answer:

Yes, Always

Step-by-step explanation:

If M is the midpoint of line KL, then M, K, and L are collinear.

As you notice in the diagram, to be collinear means part of the same line.

What’s the correct answer for this question?

Genrish500 [490]

Answer:

PO = 20

Step-by-step explanation:

They are equidistant from the centre

PG = GO

x-4=1/2x+3

Multiplying both sides by 2

2(x-4)=x+6

2x-8=x+6

2x-x = 6+8

x = 14

Now

PO = 14-4+7+3

PO = 10+10

PO = 20

Find the domain of the following piecewise function.

il63 [147K]

Answer:

$(2,8]$

Step-by-step explanation:

Given

The attached piece wise function

Required

The domain

To do this, we simply consider the inequalities that bound the values of x.

The inequalities are:

$2 < x < 4$ $4 < x < 8$ and $x \ge 8$

Combine the first two inequalities:

$2 < x < 8$ and $x \ge 8$

For the inequality to be true, we must have:

$2 < x \le 8$

In interval notation, the inequality is:

$(2,8]$

Answer: -1

Step-by-step explanation:

Find the Slope

(0, 2) , (1, 1)

Slope is equal to the change in y over the change in x, or rise over run.

change in y

m = _________

change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called r ise).

y2 − y1

m = _____

x2 − x1

Substitute in the values of x and y into the equation to find the s lope.

1 − (2)

m = _____

1 − (0)

Simplify.

Simplify the numerator.

−1

m = ____

1 − (0)

Simplify the denominator.

−1

m = ___

Divide −1 by 1.

m = −1
