Answer:

the reicprocal is -1/6.3

Step-by-step explanation:

Answer: D

Step-by-step explanation:

Answer:

C=6.4ft

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + 5^2 = c^2

4 + 4 = 16

5 + 5 = 25

16 + 25 = c^2

41 = c^2

Now you will need to find the square root of 41 which gives you 6.40 and you just round to nearest tenth..

I would have explained this further but u need it fast so..

Answer:

D.

Step-by-step explanation:

The equation given takes the point-slope form which is, [tex] y - b = m(x - a) [/tex]. Where,

(a, b) = (x, y) coordinates of a point on the line.

m = slope of the line .

To find which graph has a line equation of [tex] y - 2 = 3(x - 1) [/tex], look for the points which will give you something almost exactly as the equation if you substitute their values into [tex] y - b = m(x - a) [/tex].

Let's consider option D.

We have a given point (1, 2). a = 1, b = 2.

Substitute these into [tex] y - b = m(x - a) [/tex]

We have:

[tex] y - (2) = m(x - (1)) [/tex]

[tex] y - 2 = m(x - 1) [/tex]

As you can see, this looks almost exactly as

[tex] y - 2 = 3(x - 1) [/tex].

If you want to be certain that option D is the answer, find m by using the coordinates of any other point on the line and plug into [tex] y - 2 = m(x - 1) [/tex] to find m:

In graph D, let's take the points (0, -1)

[tex] -1 - 2 = m(0 - 1) [/tex]

[tex] -3 = m(-1) [/tex]

[tex] -3 = -m [/tex]

Divide both sides by -1

3 = m

m = 3.

Therefore, option D is the graph of the line [tex] y - 2 = 3(x - 1) [/tex].

Answer:

they are going to half to sell 100 tickets. 5 times 100 is 500

Step-by-step explanation:

pls make me brainliest

Answer:

500

Step-by-step explanation:

The turtle's rate in miles per hour is 1/5 miles/hr.

Given is that a turtle traveled 1/10 miles in 1/2 hour.

We can write the rate as -

{R} = (1/10)/(1/2)

{R} = (1/10) x 2

{R} = 1/5 miles/hr

Therefore, the turtle's rate in miles per hour is 1/5 miles/hr.

Step-by-step explanation:

f(x) = a(x - h)² + k        ← the vertex form of quadratic function where vertex is: (h, k)

Answer:

3 x − y = − 13

Step-by-step explanation:

Any equation that relates the first power of x to the first power of y produces a straight line on an x-y graph. The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept. Converting from slope intercept form to standard form takes little more than basic arithmetic.

TLDR:

To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.

Answer:

3x - y = -13

Step-by-step explanation:

y = mx + b

(This is the slope intercept form)

We want to change it to standard form, which is:

Ax + By = C

We want to rearrange as many of the numbers as we can, without actually changing the problem!

Ax = 3x

By = y

C = 13

So we must move the numbers from one side to another.

Whatever you do to one side, you do to the other.

y = 3x + 13

-3x + y = -3x - y

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

-3x + y = 13

Since we can't have our "Ax" as a negative multiply everything by -1

-1[-3x + y = 13]

3x - y = -13

That is your answer.

Answer:

Pablo Used the Commutative property to Reorder the terms. Pablo then Combined all his like terms. Pablo then Divided 21 by 3x to get 3(7+x). Pablo then subtracted 7 from 13. He got x = 6

Pablo did his math wrong.

Karla Did her work correctly. Karla used the commutative property to reorder the terms. She then combined her like terms. She subtracted 21 from itself and 39, leaving 3x and 18 on different sides of the equal sign. She divided 3x by 3 which equals x and 18 by 3 which equals Karla is correct.

Answer:

The slope is 2/5 and the y intercept is -4

Step-by-step explanation:

The slope is always the coefficient to x

Answer:

slope = [tex]\frac{2}{5}[/tex] , y- intercept = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form

with slope m = [tex]\frac{2}{5}[/tex] and y- intercept c = - 4

Answer:

y = -8

Step-by-step explanation:

All we need to is substitute for x and solve for y.

y = 8 - 2x

y = 8 - 2(8)

y = 8 - 16

y = -8

Best of Luck!

Answer:

61

Step-by-step explanation:

hi! we can start off by plugging in the number 9 for x in the equation.

f(x)=8x-11)

f(9)= 8(9)-11

= 72-11

=61

Answer:

42

Step-by-step explanation:

You get 42 by looking at the denominators 7 and 21. You times by 3 to get from 7 to 21, so you times 14 by 3 to get n, which is 42.

Answer:

42

Step-by-step explanation:

On the bottom 7 was multiplied by 3 so you would do the same to 14.

Answer:

y = 1

x = -0.75

Step-by-step explanation:

The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.

21y - 1 = 4x + 23

21y - 24 = 4x

5.25y - 6 = x

21y - 1 = 4x + 23

21y = 4x + 24

y = 4/21(5.25 - 6) + 1.14

y = 1 - 1.14 + 1.14

y = 1

5.25(1) - 6 = x

-0.75 = x
