please help with 11,12,13

Answer:

m=-1/2

Step-by-step explanation:

f(6)=-2 is (6,-2) and f(-4)=3 is (-4,3)

the equation for slope (m) is (y2-y1)/(x2-x1)

label the points:

x1=6

y2=-2

x2=-4

y2=3

now substitute into the equation:

m=(3--2)/(-4-6)

m=5/-10

m=-1/2

the slope is -1/2

hope this helps!

Answer:

560

Step-by-step Explanation

Since, 476 students make 85%.

Therefore, let x students will make 100%.

[tex] \frac{476}{85} = \frac{x}{100} \\ \\ x = \frac{476 \times 100}{85} \\ \\ x = \frac{47600}{85} \\ \\ x = {560} [/tex]

The solution is Option A.

If the volume is 47 cm³ , then the height of the cone is approximately 5 cm and volume of cone is given by ( 1/3 ) πr²h

What is a Cone?

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.

The volume of a cone is given by the equation

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

Given data ,

Let the radius of the cone be = r

Now , the value of r = 3 cm

So , the equation will be

The volume of the cone is given by the formula ,

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

a)

If the volume is 47 cm³, then the height of the cone is approximately 5 cm

So , substitute the values in the equation , we get

Volume of Cone = 47 cm³

So ,

( 1/3 ) πr²h = 47 cm³

Radius of cone r = 3 cm

Height of cone h = 5 cm

( 1/3 ) πr²h = 47 cm³

( 1/3 ) x 3.14 x 3 x 3 x 5 = 47

3.14 x 15 = 47

47 = 47

Therefore , the solution is true

Hence , If the volume is 47 cm³, then the height of the cone is approximately 5 cm and the volume of cone is given by ( 1/3 ) πr²h

Answer:

3,4 and 5 are correct........☺

Answer:

3,4,5

Step-by-step explanation:

To answer, we must go through all the expressions shown, solve them, and make sure that they are exactly like 3xy + 6yz.

1. We must distribute 3 to whatever is in the parentheses, but if you look, you can see that we have to multiply 3 by 6yz, which would come out to 18yz, and that is not in the original expression, so this one is FALSE

2. For this expression, we can rule it out because the first part of the expression would be 3xyz, and that is not a part of the original expression, this is one is FALSE

3. This expression, if you distribute the 3y, you get 3yx + 6zy, which is the same as the original expression, even if the variables are a bit jumbled, they all have the same value, so this one is TRUE

4. If you distribute y for this expression, you get y3x + y6z, which is the same as the original expression, because as I said before, the variables can be jumbled, but as long as all the values are there, we can safely say that this expression is TRUE

5. As you can see, this expression is the same as 4, so this one is also TRUE

Hope this helps :)

Actually Welcome to the Concept of the Similarities.

Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,

hence for,

1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3

hence the value of x is 12 , ===> x = 12 .

2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,

hence we apply the relation,

x = 2*4.5 ===> x = 9 units.

Answer:

y=x-1

y=-2x-4

although I cant summon a graph for this one, I can give cords

for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)

For second graph the slope is down 2 over 1, and begins at (0,-4).

(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)

Let's solve for x.

y=x−1

Step 1: Flip the equation.

x−1=y

Step 2: Add 1 to both sides.

x−1+1=y+1

x=y+1

Answer:

x=y+1

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

Let's solve for x.

y=−2x−4

Step 1: Flip the equation.

−2x−4=y

Step 2: Add 4 to both sides.

−2x−4+4=y+4

−2x=y+4

Step 3: Divide both sides by -2.

−2x

Answer:

x = -6

Step-by-step explanation:

A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.

Answer:

y = - 7

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (5, - 7 ) with y- coordinate - 7 , then

y = - 7 ← equation of line

Answer:

a). 6:51

b). 6:30 am

c). 34 minutes

Step-by-step explanation:

a). Train leaves Westchester at 6:30.

    From the arrival - departure table in column (2),

    Arrival time of the train at middlewich = 6:51

b). Kate has to reach Southam before 9:00 am

    Therefore, time of the latest train that she can catch to get to work on time is 6:30 am

     By this train she can reach at 07:19 at Southam.

c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00

                                                                                         = 00:34

                                                                                         ≈ 34 minutes
