Answer:

y-9+7(x-5)

Step-by-step explanation:

y - x1 = m ( x - y1 )

Y1 = 9

x1 = 5

m=slope (in this case 7)

Answer:

[7x-y-26=0]

Step-by-step explanation:

point slope form =

y-y1=m(x-x1)

=

y-9=7(x-5)

=

[7x-y-26=0]

you may want the y-9=7(x-5) as your answer

second part of this is for vertex form

/////// vertex form ///////Use formula y=mx+b where m is slope

y is equal to 9

x is equal to 5

b=?

m=7

9=7*5+b ---> b=  -26

////////////////

Answer:

We can fine x by using the pythagoras formula

a²+b² = c²

Which C is X

And

a= 17

b= 15

So

a² + b² = c²

(17)² + (15)² = c²

289 + 225 = c²

514 = c²

√514 = c

22.67 = c

So basically X is (22.671)

The missing side of the given right angled triangle is 8 units.

In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.

By using Pythagoras theorem, we get

17²=15²+x²

289=225+x²

x²=289-225

x²=64

x=√64

x=8 units.

Therefore, the missing side of the given right angled triangle is 8 units.

Answer:

27

Step-by-step explanation:

The number that lies halfway between 16 and 38 is 27.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

We have to determine the number that lies halfway between 16 and 38.

This is calculated by finding the average (or mean) of the two numbers. To do this, add the numbers together (16 + 38) and divide by 2.

⇒ 54/2

The result is 27.

Thus, the number that lies halfway between 16 and 38 is 27.

Step-by-step explanation:

so 8*6=48, so we know that (4*6)+(_*6) should equal 48.

4*6=24

subtract 24 by 48 and we get 24.

now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.

2nd box: 24

3rd box: 48

Step-by-step explanation:

So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.

Answer:

37/200

Step-by-step explanation:

Event/Sample Space = .185 = 18.5%

Answer:

Step-by-step explanation:

If 37 people out of 200 people opened an e-mail, you can write it as 37/200.

The number above the bar is the numerator: 37

The number below the bar is the denominator: 200

Divide the numerator by the denominator to get fraction's value:

Val = 37 ÷ 200

Val = 0.185

To calculate the percent value:

0.185 =  (Calculate fraction's value.)

0.185 × 100/100 =  

(0.185 × 100)/100 =  (Multiply that number by 100.)

18.5/100 =

18.5%;  (Add the percent sign % to it.)

So that's how you get 18.5%

Answer:

y = 30

z = 115

Step-by-step explanation:

z° + 65° = 180°

(Exterior Angles on the same side of transversal)

z° = 180° - 65°

z° = 115°

z = 115

(5y - 85)° + z° = 180°

(Linear pair angles)

(5y - 85)° + 115° = 180°

(5y - 85)° = 180° - 115°

(5y - 85)° = 65°

5y - 85 = 65

5y = 65 + 85

5y = 150

y = 150/5

Answer:

is this algebra

Step-by-step explanation:

Answer:

1.)

A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.

Slope calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]

B.) The coordinate (0,0) represents that no laps have been completed nor has the time started

C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes

2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.

Slope Calculation:

[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]

3.)

A.) The constant of proportionality is 7/4 or 1.75

B.) y = 7/4x

4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

A conjecture is a conclusion or a proposition that is proffered on a tentative basis without proof.

1) According to given pattern, the next shape will be a shape a red square.

2) The given numbers are multiplied by 3 in every next term, 3, 3*3 = 9, 9*3 = 27 and 27*3 = 81 so, next number will be 81*3 = 243.

3) The 4th one is a pattern of binary system:

000, 001,010,011

Therefore, the next one would be 100,101.... That means red, blue, blue.
