Find the difference. 6rs – (-2rs)

First u have to find Y2-Y1/X2-X1 , so u will replace the number to the y and x value.
step1: subtract Y2 and Y1. then find the different of x_value, which is 14-10/-7-8
step2: after u find the differences, u will get 4/(-15) .
finally, you will get a slope. y=4/-15x+b.

One integer should be x
and the second one should be x+1 
according to the question 
2x+10 = 3(x+1) - 7
2x+10 = 3x+3-7
2x +10 = 3x-4 
2x-3x+10+4 = 0
-x + 14= 0
-x = -14
minus got canceled out
therefore,
x = 14 and 
x+1 
14+ 1
15
so the numbers are 14 and 15

X and x+2 are the numbers

x+(x+2)=3(x+2)-2x
2x+2=3x+6-2x
2-6=x
x=4
x+2=6

the numbers are: 4 and 6

1426, 1446, 1466, 1486, 2426, 2446, 2466, 2486, 3426, 3446, 3486, 3466

Way one: put the biggest number in your head in this case 5 then count up 4 then 3 more so you get 12 

way 2: draw 3 tally marks then 4 more then 5 more then count them all together to get the sum 12

hope this helped:)

Answer:

Hence, we have:

               a= 3 and b= 4

Step-by-step explanation:

It is given that:

A complex number, (a + bi), multiplied by (2 + 3i) and added to -i gives the product of (-11 + 5i) and (1 – i).

i.e.

Since, we know that :

Hence, we have:

i.e. we have:

and

On multiplying equation (1) by 2 and equation (2) by 3 we get:

on putting the value of a into equation (1) we get:

I would say the variable is the # of months. if a member joined for 6 months they would pay the 125 registration fee and then $60.42/ month. 

378 is the number since it is found to be divisible by not only 7 but also 3.

I think the answer is 2,304

Let y=f(x)
y=sqrt(10-3x)
you want to make x the subject

square both sides
y²=10-3x
3x=10-y²
x=(10-y²)/3

now replace y with x
f^-1(x)=(10-x²)/3

Total = 36oz
Amount of 18% solution = x
Amount of 9% solution = 36 - x

Using the fact that (amount of solution) * (percent HCl) = amount HCl we can set up an expression for the amount HCl in a mixture of 18% and 9% solutions with a total volume of 36oz.

Amount of HCl = x*0.18 + (36 - x)*0.09

If we divide this by the amount of solution we get percent HCl, and we have a target of 10% HCl. Now we have an equation to solve,

[x*0.18 + (36 - x)*0.09]/36 = 0.1

x*0.09 + 3.24 = 3.6

.09x = 0.36
x = 4

Therefore,
4 ounces of 18% HCl solution and 32 ounces of 9% HCl solution

Check:
[(4*.18) + (.09*32)]/36 = 0.1?
0.1 = 0.1   Yes.

Let the breadth be x m.
So, length = 4x m.
Area of the rectangle = 1936m sq.
So,
4x × x = 1936
4x^2 = 1936
x^2 = 1936/4
x^2 = 484
x = √484
x = √22×22
x = 22
Hence, breadth = 22m.
Length = (4×22)m = 88m.

Surface of a cubical box=6(side²)

1)We have to calculate the surface of this cubical box.
Rate=cost of painting / surface  ⇒surface=cost of painting/rate

Data:
Rate=$15/m²
cost of painting=$1440

Surface=$1440/($15/m²)=96 m²

2)We find out the length of the side:

Surface of a cubical box=6(side²)

Data:
Surface of a cubical box=96 m2

Therefore:
96m²=6 (side²)
side²=96 m²/6
side²=16 m²
side=√(16 m²)=4 m

3) We find the volume of a cubical box.
volume=(side³)
volume=(4 m)³
volume=64 m³

Answer: the volume of this cubical box would be 64 m³.

F{G[H(2)]} = F{G[2*2]} = F{G[4]} = F{3*4+2} = F{14} = 2*14-1 = 27

X equals 2. 2 times 2 equals 4, then you multiply it by 2 again, which equals 8. Basically you just have to find the square root of 8, which is 2.

I hope this helps you

F(x) = 5 tan x

First, add together the number of all the animals.
5+11+4+4=24

Then, find the number of goats and put that into a ratio with 24

4:24
1:6
This ratio means that for every 6 animals there is 1 goat

Hope this helps :D

-1-4 divided by 2-(-2) or (4) your rise is Y which is -5 and your run is X which is 4

1) Set up an equation to model the situation.
    cos(Ф) = x/10

2) Take the derivative/gradient in terms of time (t) to find the related rates.
    d[cos(Ф)]/dt = d[x/10]/dt
    -sin(Ф)*dФ/dt = (1/10)*dx/dt
    dФ/dt = -(dx/dt)/(10*sin(Ф))

3) Substitute in the constants for the moment in time
    Given: dx/dt = 0.6; x=6 -> Ф = cos-1(6/10) = ~0.93rad
    Therefore: dФ/dt = -3/40 rad/sec

Add the numbers together, and you'll get the answer.

Idk, the other person's answer <3

Answer:$55

Step-by-step explanation:

Y=5(4)-3(b)+8
y=20-3b+8
y=28-3b
dunno what b is

2(5-n)=-2+(-1*n)
2(5-n)=-n-2
distribute
10-2n=-n-2
add 2n to both sides
10=n-2
add 2 to both sides
12=n

The value of the three is 300,000

I hope this helps you n+n+1=-67 2n=-67-1 2n=-68 n=-34 n+1=-34+1=-33

N is the number
2(n-2)=16
divide both sides by 2
n-2=8
add 2 to both sides
n=10

the number is 10
