Answer: y = 1x -3

The 1 is not necessary so

y= x - 3

Step-by-step explanation:

(y- y1) = m(x -x1). First

Substitute y and x-values from the given coordinates and solve for x.

7-(-1)=m(10-2)

8 = m(8) 8/8=1 T

m= 1 The slope, m is 1

Then substitute values of y and x from either given coordinate into the equation and solve for b, the y-intercept.

y=mx+b

-1= 1(2)+b

-1=2+b subtract 2 from both sides.

-1-2 = b

-3 = b

OR

7= 10 + b

-10 +7 = b

-3 = b

Finally, write the equation with the values for m and b

y = 1x +(-3) Simplify & Rewrite

y= x - 3

Answer:

3, 6, 2, 1, 4, 5

Step-by-step explanation:

Option A is correct, (5, 9) is the point not on the graph of the function y = x - 4.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given function is y=x-4.

Let su check all the given points whether they are point of the given graph or not.

The point (5, 9) is not on the graph of the function  y = x - 4

Because when x = 5, y = 1, not 9.

The point (234, 230) is  on the graph of the function  y = x - 4

Because when x = 234, y =230

The point (7, 3) is  on the graph of the function  y = x - 4

Because when x = 7, y =3

The point (12, 8) is  on the graph of the function  y = x - 4

Because when x = 12, y =8

Hence, (5, 9) is the point not on the graph of the function y = x - 4.

Answer:

12 guests(13 including yourself), 78 ounces of dough, and 52 ounces of sauce.

Step-by-step explanation:

So what you want to do is to first add up the dough and the sauce which is 10. then you want to divide 130 by 10 and you get 13(130/10=13) Now we subtract 1 from 13 and that how many guests you have which is 12. now we time 6 by 13 which is 78(6*13=78) so 78 ounces of dough. Now we time 4 by 13 and we get 52(4*13=52) so 52 ounces of sauce. Now to make sure it's right we need to add 78 and 52 together and we get 130(78+52=130) And that's all

Answer:

original coordinates A[-4,5], B[-3,1], C[-5,2

new coordinates [3,1], B[2,5] C[4,4]

Step-by-step explanation:

ok so the x is the horazontal line and the Y is the vertical line when your writing cooodinates you always write the X first then the Y. so to find the origanal corrdinates which i'm assuming are the coordinates for the blue triangle you have to find the first point so the one labled A, you look at the numbers on X so the horizontal line, and find out which number on that line has point A on it and you record that number this is the X then you look at the   numbers on the Y line, (the vertical line) and see which number has point A on it and record this number this is the Y do this for all the other points and you will have all of their coordinates.

Answer:

I think it is 192

Step-by-step explanation:

Volume of cube: 5 x 4 x 8 = 160

Area of diagonal: 160/2 = 80

Length of diagonal: 80 / 0.5 x 3 = 480

AB = 480 / 5 x 2 = 192

Answer:

(a)19.5 per hour

(b)Kaylee earns more per hour.

Step-by-step explanation:

a.) To find the unit rate/hourly rate :

39÷2=19.5 per hour.

b.)Kaylee eanrs more considering that Joey earns 16.50$ per hour as opposed to 19.50$ per hour.

Answer:

(a) Kaylee earns $19.50 per hour.

(b) Kaylee earns more money per hour than Joey.

Step-by-step explanation:

x = # of hrs. worked

y = amount of money earned

Joey:

y = 16.50x

Kaylee:

Time (h) 2, 5, 8, 10

Money earned ($) 39, 97.50, 156, 195

y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (2,39) and (8,156) to find the slope of this table.

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]

y = mx + b

y = 19.5x + b

I will be using (2, 39) to find the value of b

(2, 39)

y = 19.5x + b

39 = 19.5(2) + b

39 = 39 + b

-39  -39

0 = b

y = 19.5x + b ==> y = 17.7x + 0 =  OR  y = 19.5x (since the value of b is 0)

(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.

y = 19.5x

She earns $19.50 per hour.

(b)

Joey: y = 16.50x (earns $16.50 per hour)

Kaylee: y = 19.5x (earns $19.50 per hour)

As you can see, Kaylee earns more money per hour than Joey.

Answer:

(i) 84 cm.

(ii) 5635π cm^2

Step-by-step explanation:

(i)

The volume of the cone = 1/3 π r^2 h

= 1/3 π 35^2 h.

The volume of the hemisphere = 2/3 π 35^3.

As the volume of the cone is 1 1/5 ( = 6/5) times the volume of the hemisphere:

1/3 π 35^2 h = 2/3 π 35^3 * 6/5

h = 2/3 π 35^3 * 6/5 / 1/3 π 35^2

h = 84 cm (answer).

(ii) Surface area of the hemisphere = 2 π * 35^2 = 2450π cm^2.

Surface area of the cone = π r l where l = slant height.

l = √(35^2 + 84^2) = 91 cm.

So the surface area of the cone = 35*91 π = 3185π.

So the total surface area of the solid is 3185π + 2450π

= 5635π cm^2.

i hope this work for you

The height and the base area of the cone are 6 units and 4π square units. Then the volume of the cone is 24π.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The height (h = 6) and the base area (b = 4π) of a cone is given.

Then the volume of the cone will be

Volume = b × h

Volume = 4π × 6

Volume = 24π
