how many are 15 x 15 ?​

Answer:

The other endpoint is (7, -5)

Step-by-step explanation:

We can use the formula for the midpoint to find the coordinates of the other endpoint of the segment BC:

xm = x1 + (x2 - x1)/2

ym = y1 + (y2 - y1)/2

For our case, replacing the given coordinates and solving for x2 and y2 (the coordinates of the other endpoint) we get:

For x2:

xm = x1 + (x2 - x1)/2

5 = 3 + (x2 - 3)/2

5 - 3 = (x2 - 3)/2

2 = (x2 - 3)/2

4 = x2 - 3

x2 = 4 + 3 = 7

For y2:

ym = y1 + (y2 - y1)/2

-2 = 1 + (y2 - 1)/2

-2 -1 = (y2 - 1)/2

-3 = (y2 - 1)/2

-6 = y2 - 1

y2 = -6 + 1 = -5

Therefore the other endpoint is (7, -5)

Answer:

20,9

Step-by-step explanation:

this is how I did=x=1st, y=2nd; x=4y-16 and x+y=29; thus 4y-16+y=29; 5y-16=29; 5y=45; y=45/5=9, once you know y=9, put in equation, 4y-16=×, (4*9)-16=x, 36-16=x, 20=x

The system of equations are x + y = 29 and y = 4x - 16

The two numbers are 9 and 20 respectively

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be x

Let the second number be y

Now , the equation will be

One number is 16 less than 4 times the second number

So , y = 4x - 16   be equation (1)

And , Sum of the numbers is 29

So , x + y = 29   be equation (2)

And , y = 29 - x  be equation (3)

Substituting the value of y from equation (3) in equation (1) , we get

29 - x = 4x - 16   be equation (4)

On simplifying the equation , we get

Adding x on both sides of the equation , we get

5x - 16 = 29

Adding 16 on both sides of the equation , we get

5x = 45

Divide by 5 on both sides of the equation , we get

x = 9

Substituting the value of x in equation (2) , we get

y = 20

Therefore , the two numbers are 9 and 20

Hence , the equations are solved

Answer:

34 pages

Step-by-step explanation:

For the first three pages, Sonia is already down 13 dollars.

106-13=93 dollars left

93/3 dollars per page =31

31+those three first pages=34 pages

Answer:

34

Step-by-step explanation:

When you subtract 13 by 106 you will receive 93. Then you divide 93 by 3 and get 31. Add 3 pages to 31 and get 34. (If you're wondering where i have gotten the 3 it is from the first 3 pages Sonia paid for)

Answer:

x=3

Step-by-step explanation:

Answer:

[tex]x=3[/tex] or the point (3, 0)

Step-by-step explanation:

Recall that the zero(s) of a function is wherever the graph crosses the x-axis.

In other words, to find the zeros of a function, we set the function equal to zero and solve for x.

We are given the function:

[tex]f(x)=2x-6[/tex]

Setting the function to zero yields:

[tex]0=2x-6[/tex]

Solve for x:

[tex]\displaystyle \begin{aligned} 2x -6 & = 0 \\ \\ 2x & = 6 \\ \\ x & = 3\end{aligned}[/tex]

Therefore, a zero of our function is x = 3 at (3, 0).

Answer:

[tex]f(x)=\frac{3}{2}x+4[/tex]

Step-by-step explanation:

The Slope-Intercept Form equation is f(x)=mx+b

m= slope

b= y-intercept

you are already given the slope ([tex]\frac{3}{2}[/tex]), so you only have to find the y-intercept.

first, plug in the x of the point given (-6) into the equation

[tex]\frac{3}{2}[/tex](-6)=-9

then you find the difference of the answer and the y of the given point (-5)

-5-(-9)

-5+9=4

b=+4

Answer:

r = 1

Step-by-step explanation:

Step 1: Write equation

-3r + 18 = 15r

Step 2: Solve for r

Step 3: Check

Plug in r to verify it's a solution.

-3(1) + 18 = 15(1)

-3 + 18 = 15

15 = 15

Step-by-step explanation:

- 3r - 15r = -18 .... Moved variables to one side and constants to the other

- 18r = - 18 ..... Simplified

r = 1 ..... Divided to isolate the r

Check:

Plug in 1 for r

-3(1) +18 = 15(1)

- 3+18 = 15

15 = 15 .... Therefore 1 is correct

Answer is 1

Answer:

a=4

Step-by-step explanation:

Hi there!

We are looking for the value of [tex]a[/tex]. We know that [tex]b=11[/tex] and [tex]c=\sqrt{137}[/tex].

We'll start with the Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Now, we'll subtract [tex]b^{2}[/tex] from both sides so that [tex]a^{2}[/tex] is by itself.

[tex]a^{2} =c^{2} -b^{2}[/tex]

We can now substitute our known values of [tex]b[/tex] and [tex]c[/tex] into the equation. Make sure to put the substituted values in parenthesis.

[tex]a^{2} = (\sqrt{137}) ^{2} -(11)^2[/tex]

Let's apply the exponents to the values we substituted in:

[tex]a^2=137-121[/tex]

[tex]a^2=16[/tex]

Now, to eliminate the exponent on [tex]a[/tex], we take the square root of both sides:

[tex]a=\sqrt{16}[/tex]

[tex]a=4[/tex]

Answer:

(3,0)

Step-by-step explanation:

to find the x-intercept, you have to plug in 0 for y to solve for x. this would be -6x-2(0)=-18. this simplifies to -6x=-18. we can divide by -6 on both sides. this results in x=3. this is the value of the x-coordinate, so the answer is (3,0) since the x-intercept is where the line crosses/touches the x-axis.

Olivia is 24 years old

step by step

because Olivia is 20 years old and Mike is 4 years older than her so Olivia is 24 years old

Answer: Olivia is 8 years old.

Step-by-step explanation:

"O" stands for Olivia

O+4 = M

O + O+4 = 20

2O +4=20

2O=16

2O/2 = 16/2

O = 8

Mike is 4 years older, so Mike is 12 years old

12+8 = 20

1. Since it takes 1[tex]\frac{1}{2}[/tex] cups to make 2 pints, multiply 1 [tex]\frac{1}{2}[/tex] cups twice to equal 4 pints

You'll need 3 cups for 4 pints

2. Since we have 1 pint left, divide 1[tex]\frac{1}{2}[/tex] by 2.

Answer:

Jim can arrange the 7 songs on the playlist in  5040 different ways.

Step-by-step explanation:

Given

[tex]Songs = 7[/tex]

Required

Ways of arrangement

Since, there is no restriction and conditions.

The songs can be arranged in

[tex]Ways = 7![/tex]

This is so because each song will have a distinct position:

So, we have

[tex]Ways = 7 * 6 * 5 * 4 * 3 * 2 * 1[/tex]

[tex]Ways = 5040[/tex]

The number of ways that can Jim arrange the 7 songs on the playlist is 5040.

Since Suppose Jim is going to build a playlist that contains 7 songs.

So here the number of ways should be

= 7!

[tex]= 7\times 6\times 5\times 4\times 3\times 2\times 1[/tex]

= 5040

hence, The number of ways that can Jim arrange the 7 songs on the playlist is 5040.
