Find the slope?

Answers

Answer:

1/4

Step-by-step explanation:

the equation for slope is  (y2 - y1) / (x2 - x1)

so the equation is (4-8)/(3-19)

= -4/-16

= 4/16

= 1/4, therefore, the slope is 1/4 or 0.25 as a decimal

Answers

9514 1404 393

Answer:

  factor out 5^19

Step-by-step explanation:

a) Reason from parity:

  both 5^20 and 5^19 are products with only odd numbers (5) as factors. Hence each is an odd number. The difference of odd numbers is always even.

__

b) Factor:

  5^20 -5^19 = 5^19(5 -1) = 5^19×4

This product has an even factor (4), so is even.

Answer:

The rate is 15 minutes per meter.

Step-by-step explanation:

It takes 9 minutes to fill a depth of  meters.

Filling   meters take 9 minutes time.

Filling 3 meters of the aquarium takes  = 45 minutes time (Multiplying by 5 both the numbers).

In order to fill 1 meter of the aquarium it will take  minutes (Dividing by 3 both the numerical values).

Answer:   20 minutes per meter

===================================================

Work Shown:

8 minutes = (2/5) meters

5*(8 minutes) = 5*( (2/5) meters )

40 minutes = 2 meters

40/2 minutes = 2/2 meters

20 minutes = 1 meter

The unit rate in minutes per meter is 20 minutes per meter.

In other words, it takes 20 minutes to raise the level 1 meter.

which shows the use of the associative property?

Answers

Answer:

The correct answer is Option 2:

[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

Step-by-step explanation:

Associative property consists of three quantities. Associative property for addition states that the result of adding three numbers will be same no matter what the order of addition is.

Let a,b and c be three numbers

Then associative property can be stated as:

[tex]a+(b+c) = (a+b)+c[/tex]

Now looking at the options it can be observed that the following choice shows the associative property

[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

Hence,

The correct answer is Option 2:

[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

counterclockwise

Q= (-5,2)

R= (1,3)

S= (0,0)

T= (-3,-2)

Step-by-step explanation:

this might not be right im a little rusty on my transformations but here goes nothing.

i dont know if this is a clockwise or a counter clockwise rotation so ill do both options.

clockwise (x,y) - (y,-x)

q=(2,5) - (5,-2)

r=(3,-1) - (-1,-3)

s=(0,0) - (0,0)

t=(-2,3) - (3,2)

counterclockwise (x,y) - (-y,x)

q=(2,5) - (-5,2)

r=(3,-1) - (1,3)

s=(0,0) - (0,0)

t=(-2,3) - (-3,-2)

Which statement is true about the graphs of the two lines y=-x+2 and y=-x- ?
O The lines are perpendicular to each other because - and - are opposite reciprocals of each other.
The lines are perpendicular to each other because 2 and - 1 are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 3 are not opposite reciprocals of
each other.

Answers

Answer:

The correct option is Option C

Step-by-step explanation:

We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]

The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]

In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)

In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)

The opposite reciprocal of -4/5 is 5/4  

So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.

If the lines are parallel there slope must be same. Hence lines are not parallel as well.

So, The correct option is Option C

c

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.

How to solve:

First use the formula: C = 3.14dReplace the d value with 30 and solve the equation:

C = 3.14 x 30    ⇒   94.2477796077

Then solve the equation again but 21 as the d value:

C = 3.14 x 21     ⇒   65.9734457254

Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8

write an equation in slope-intercept form of the line that passes through the given points (-4,-2) (8,-2)

Answers

Answer:

y=-2

Step-by-step explanation:

First, find the slope using the slope formula: m=y2-y1/x2-x1

Plug the numbers into the equation and get 0

Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)

y+2=0(x+4)

Distribute and simplify to get the final answer.

y+2=0+0

y=-2

So you would graph the two points to make the line, then find the slope by doing rise/run. The slope equation is y=mx +b and m is slope so u would plug that in. Then you would find the y-int / b by finding the point on the line where it crosses the y acis/ when x is zero! There u hv it!
