what is the equation in point slope form of a line that passes through the points (-4,-1)and5,7)
​

Answers

Answer 1

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

using the image attached as reference

(-4,-1) - the -4 becomes x1, and the -1 becomes y1

(5,7)  - the 5 becomes x 2 and the 7 becomes y2

plug this information into the equation

      7-(-1)

m=----------      

      5-(-4)

solve

       8

m=----------    

        9

​so your slope would become 8/9

Answers

Answer:

-610793236

Step-by-step explanation:

2+24/654-7986x76483 (punch it in the calculator)

= -610793236

or if you need to "show your answer"

2+24/654-7986x76483

= 2+24/654-610793238

= 2+ 0.36- 610793238

= 2+ (-610793238)

= - 610793236

How do I find the slope?

Answers

Answer:

Slope is:

y = -7/2 x + 5

Step-by-step explanation:

7x + 2y = 10                 You need to get the y by itself on the left

-7x  + 2y = -7x     Subtract the 7x on both sides. The -7x cancels on the left

-----------------------

2y = -7x + 10        You need to get the y by itself on the left. Divide the 2 to                          

--- = ----- + ----       each component. ( Everything on both sides )

2   =  2   + 2

y = -7      + 5         The 2's on the left would cancel. Divide for the rest

     ---- x                Do not turn the -7 / 2 to a decimal! Keep it as it is!

      2

The linear equation is:

y = mx + b

y = y-value from coordinate

m = slope

x = x-value from coordinate

b = y - intercept

M = -7/2

We do not know what x and y is

b = 5

Hope this helps!!

I need help, the options are: Corresponding Angles, Vertical Angles, Alternate interior angles, linear pair, alternate exterior angles, and consecutive interior angles.

Answers

Answer:

✔️ <1 and <3 => Vertical angles

✔️<2 and <6 => alternate exterior angles

✔️<2 and <4 => corresponding angles

✔️<3 and <7 => alternate interior angles.

✔️<4 and <3 => consecutive interior angles.

✔️<7 and <6 => linear pair angles.

Step-by-step explanation:

✔️ <1 and <3 are opposite angles formed when two straight lines intersect. They both share the same vertex. Thus, they are vertical angles, which are congruent to each other.

<1 and <3 are vertical angles.

✔️<2 and <6 are alternate exterior angles.

<2 and <6 both lie outside the straight lines cut across by the transversal, and they also lie in the side of the transversal alternating each other

✔️<2 and <4 are corresponding angles.

They both take the same position on the same side of the transversal.

✔️<3 and <7 are alternate interior angles.

They are alternating angles along the transversal that are located just within the two lines intersected by the transversal.

✔️<4 and <3 are consecutive interior angles.

They are angles on the same side of the transversal but lie within the two straight lines intercepted by the transversal.

✔️<7 and <6 are linear pair angles.

They are angles on a straight line, and sum up to 180°.

Shown here is a mathematical step taken when solving an equation. Identify the mathematical reason or property used to simplify from the first step to the second step. 8D=56. D=7

Answers

Answer:

D. Division Property of Equality

Step-by-step explanation:

Given that [tex] 8D = 56 [/tex], to find the value of D, the property of equality that needs to be applied here would be the one that would make both sides equal by performing the same operation on both sides of the equation.

Thus:

Applying the the Division Property of Equality, we would divide both sides by 8.

[tex] \frac{8D}{8} = \frac{56}{8} [/tex]

[tex] D = 7 [/tex]

This will leave you with D standing alone. Of which value is 7.


Ann can accomplish his school project in x hours. What part of his school project can be completed
by Ann after 2 hours?

Answers

Answer:

T = [tex]\frac{2}{x}[/tex]

Step-by-step explanation:

Since we are only given the total number of hours that the project will take and nothing else, we can simply divide the 2 hours by the total number of hours in order to create an expression for the percent that will be completed in that time which in this expression would be represented by the variable T.

T = [tex]\frac{2}{x}[/tex]

We can then use this equation by plugging in a value for x in order to calculate the percent of the project that will be completed in 2 hours.

The sum of 2 times a number and twice its reciprocal is 20/3. Find the numbers.


Please show work because I am so lost.

Answers

Answer:

Let x represent the number from the sentence.

Step-by-step explanation:

2(x) + 2(1/x) = 20/3

2x + 2/x = 20/3

multiply both sides of the equation by 3x

6x + 6 = 20x

6x - 20x + 6 = 0

6x - 18x - 2x + 6 = 0

6x(x-3 -2(x-3) = 0

(6x-2 = 0 or x-3 = 0

6x = 2 or x = 3

x = 2/6

x = 1/3

Since x represented the number

Therefore x = 1/3 or 3

5/4÷7/2

multiply first number by reciprocal of second number. To get the reciprocal, switch the numerator and denominator.

Answer:

5/14

Step-by-step explanation:

Remember: Keep, change, flip

Keep: 1 1/4 = 5/4

Change: ÷ -> ×

Flip: 3 1/2 = 7/2 = 2/7 flipped

Original: 5/4 ÷ 7/2 = x

Keep change flip method: 5/4 × 2/7 = x

x = 10/28 which simplifies to 5/14

x = 5/14

A light bulb consumes 2700 watts an hour in 4 days and 12 hours. How many watts does it consume in a day

Answers

Answer:

The light bulb will consume 600 watts in one day.

Step-by-step explanation:

Let us suppose the light bulb is continuously ON.

As a light bulb consumes 2700 watts an hour in 4 days and 12 hours.

4 days and 12 hours = 96 hours + 12 hours = 108 hours

So, a light bulb consumes 2700 watts in 108 hours.

Hence,

A light bulb consuming the watts per hour will be: 2700/108 = 25 watts

As a light bulb consumes 25 watts in one hour, there are 24 hours in a day.

Light bulb consuming total no of watts in a day = 25 × 24 = 600 watts

Therefore, the light bulb will consume 600 watts in one day.

2ND METHOD

4 days and 12 hours = 4.5 days

Total no of watts cosumed by a light bulb in 4.5 days = 2700 watts

so

Total number watts consumed in a day = 2700 / 4.5 = 600 watts.

Therefore, the light bulb will consume 600 watts in one day
