Answer:

3rd choice

Step-by-step explanation:

y = mx + b

Look at where the line crosses the y-axis. That is the y-intercept. It is 2, so b = 2, and you have

y = mx + 2

Now we need the slope, m.

Start at (0, 2). Go up 1 and right 2.

slope = m = rise/run = 1/2

Now you have

y = 1/2 x + 2

Answer: 3rd choice

Answer:

[tex]c)y=\frac{1}{2}x+2[/tex]

Step-by-step explanation:

[tex]We\ know\ that,\\The\ equation\ of\ a\ graph\ is\ given\ by\ the\ formula:\\y=mx+b,\ where\ m\ is\ the\ slope\ of\ the\ graph,\ and\ b\ is\ the\ y-intercept;\\Here,\\First,\\Lets\ calculate\ the\ slope\ of\ the\ graph:\\We\ also\ know\ that,\\Slope(m)=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}\\Lets\ consider\ any\ two\ points\ which\ lie\ on\ the\ line:\\(2,3),(-2,1)\\Hence,\\The\ slope\ of\ the\ given\ line=\frac{1-3}{-2-2}=\frac{-2}{-4}=\frac{1}{2}\\Hence,\\m=\frac{1}{2}\\[/tex]

[tex]Now,\\The\ y-intercept\ is\ the\ point\ at\ which\ the\ graph\ intersects\ the\ whole\ y-axis.\\Hence,\\Here,\\The\ line\ of\ the\ graph\ cuts\ the\ y-axis\ at\ (0,2).\\The\ y-intercept\ of\ the\ line=2\\Hence,\\The\ equation\ of\ the\ line:\\y=(\frac{1}{2})x+(+2)\\y=\frac{1}{2}x+2[/tex]

Answer:

x= 29

Step-by-step explanation:

Since, ∆ABC is congruent to ∆DEF,

AB= DE....(i)

BC= EF....(ii)

AC= DF....(iii)

From (ii), BC= EF,

So, 3x-7 = 20

3x= 20+7= 27

x= 27/3 = 9

Hope it helps you

From the congruent triangles value of x is 9 units.

Given that, ∆ABC≅∆DEF, and AB=15, BC=20, and FE=3x-7.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Since, ∆ABC is congruent to ∆DEF,

AB= DE --------(I)

BC= EF --------(II)

AC= DF --------(III)

From (II), BC= EF,

So, 3x-7 = 20

3x= 20+7= 27

x= 27/3 = 9 units

Therefore, from the congruent triangles value of x is 9 units.

Answer:

2.4 cm

Step-by-step explanation:

We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.

Let's find the midpoint of AB.

Next let's find the midpoint of BC.

In order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.

Therefore, the difference between the midpoints of AB and BC is 2.4 cm.

Answer:

40

Step-by-step explanation:

A rain barrel is 65$ full

There are 26 gallons of water in the barrel

Therefore the numberr of gallons of water the barrel will hold can be calculated as follows

= 2600/65

= 40

Hence the barrel will hold 40 gallons of water

Answer:

19.79 ft

Step-by-step explanation:

Given data

We are given that the dimension of the room is

Length= 14ft

Width= 14ft

Required

The Diagonal of the room

Applying the Pythagoras theorem we have

D^2= L^2+W^2

substitute

D^2= 14^2+14^2

D^2= 196+196

D^2= 392

D= √392

D= 19.79 ft

Hence the distance from one corner to the other is 19.79 ft

Answer:

  18 6/7 ft

Step-by-step explanation:

The circumference is given by the formula ...

  C = 2πr

The circumference of the larger circle is then ...

  C' = 2π(r+3) = 2πr +6π

The difference in circumference is ...

  C' -C = (2πr +6π) -(2πr) = 6π

For the given value of π, the difference in circumference is ...

  (22/7)(6 ft) = 132/7 ft = 18 6/7 ft

The circumference of the outer circle is greater by 18 6/7 ft.

Answer:

Step-by-step explanation:

If I'm reading your shorthand correctly you want this to be rounded to 3 digits.

There are two answers:

1) 8.27 * 10^2         which is the best way to show 3 significant digits or

2) 827                    which works but is not as good as the scientific notation.

The reason is that you cannot be absolutely sure how many digits there are. It might just be a convenient way to show a number informally without worrying about significant figures.

Answer:

a). -6x³ - 12x²    b). -12     c). 12

Step-by-step explanation:

a). (g x f)(x) can also equal f(g(x))

= f (2x +4)

= -3x² (2x+4)

= -6x³ - 12x²

b). f(g(-1))

g(-1) = 2(-1) + 4

= -2 + 4

= 2

f(2) = -3x²

= -3(2)²

= -12

c). g(h(3))

h(3) = 3x-1/2

= 3(3) - 1 / 2

= 4

g(4) = 2x + 4

= 2(4) + 4

= 12

Answer: Area of the dotted line square is 120ft^2 and area of figure a. is 60 ft^2

Step-by-step explanation:

So the area of the dotted square/rectangle is 120 because we can take the entire length and width which is 10ft and 12 ft and multiply to find the area

Now the weird looking shape can be a little tricky but we have to remember that it is alot easier to solve for area of separate shapes. So if you look at the side of the 5ft and look all the way down we can see this figure makes both a rectangle and a triangle. The rectangle has a length of 10 and width of 4 so the area of that is 40ft^2. Now for the triangle. To find the base and height lengths 12-4 from the width of the rectangle which is 8 and 10-5 from height of the triangle so 5. Area of triangles is b*h/2 so 8*5/2= 20ft^2. So 40ft^2(rectangle)+20ft^2(triangle) is 60ft^2 area of figure a.
