Answer:

y= -10

Step-by-step explanation:

y=6(-3)+8

y=-18+8

y= -10

I think it might be 20???

Step-by-step explanation:

4 + x + 3x = 4 ( 5x ) - 3 ( x ) - 10

4 + x + 3x = 4 + 5x - 3 + x - 10

x + 3x + 5x + x = 4 + 4 - 3 - 10

10x = 21

10x % 10 = 21 % 10

x = 2,1

Step-by-step explanation:

Step 1: Draw your trend line.

You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:

trend line equation

Step 2: Locate two points on the line.

Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.

For the trend line that we just drew, we can see these two easily identifiable points.

trend line equation

We can easily identify these two points as (3, 3) and (12, 6).

Step 3: Plug these two points into the formula for slope.

The formula for slope is this one:

trend line equation

We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:

trend line equation

So our slope is 1/3.

Pythogorus Property:-

(base^2 )+(altitude^2)=(hypotenuse^2)

Answer:

The sum of two angle is 180 (supplementary)

given angle = 3:1

first angle =3x

2 nd angle=1x

3x+1x =180

4x =180

x = 180/ 4

x = 45

so first angle =3x   x = 45

                   = 3×45

                    = 135 degree

2nd angle = 1x

               =45 degree

ans

Both angles are 135 and 45

Answer:

200

Step-by-step explanation:

2000 because 8 is big so you are able to round it to become 2 in the 1000

Answer:

6 weeks

Step-by-step explanation:

Theo savings = 18 + 4.50x

James = 4x

where x = number of weeks

Theo : James =  15 : 8

18 + 4.50x : 4x =  15 : 8

(18 + 4.50x ) / 4x =  15 / 8

Cross multiply;

8 (18 + 4.50x) = 15 (4x)

144 + 36x = 60x

60x - 36x = 144

24x = 144

x = 144 / 24 = 6 weeks

Answer:

10/3 of the cabinet

Step-by-step explanation:

Given data

We are given that in 1/5 hour they can install 2/3 kitchen cabinet

We want to find out how many of the kitchen cabinet they can install in one hour

Hence

in 1/5 hour they installed 2/3 cabinet

in 1 hour they will install x cabinet

cross multiply

x* 1/5= 2/3

divide both sides by 1/5

x= 2/3/1/5

x= 2/3*5/1

x= 10/3 of the cabinet

Answer:

100

Step-by-step explanation:

340 - (4 * 60) = 100

Answer:

length is 10, width is 7

Step-by-step explanation:

Area of a rectangle = length * width = lw

Area is known to be 70

length = twice width - 4 = 2w-4 = l

width=w

so A = lw = (2w-4)w = 70

(2w-4)w=70

2w^2-4w=70

2w^2-4w-70=0, divide by 2

w^2 - 2w - 35 = 0, not sure how your class solves these, I see visually

(w-7)(w+5)=0

w=7 or w=-5, -5 makes no sense in the real world (negative length), so w=7

l = 2w-4 = 2(7)-4 = 14-4 = 10

Answer:

The volume of a sphere is 4/3 * πr³

With a radius of 3, you've got:

4/3 × π3³

= 4/3 × π × 27

= 4 × π × 9

= 45π

why is my brainly sux lol due dude.ex

Answer A: 84π

Answer B: I'm also confused. If anyone else knows can you please help me also. Sorry for not answering B. I hope this helps though.

Step-by-step explanation:

Answer A:

V=1/3π 6^2 (7) Since 12 is a diameter you half it which is 6

V=1/3π 36(7)

V=1/3π 252

V= 252π/3

V=84π

Answer:

a = 24

Step-by-step explanation:

sin 12° / 10 = sin 150° / a

cross-multiply:

a · sin 12° = 10 · sin 150°

a = 5 / sin 12°

a = 24

Answer:

a = 24

Actually Welcome to the Concept of the Cube roots.

Answer is D.)

[tex]7x {y}^{2} \sqrt[3]{2xy} [/tex]

as, x^3 will come out and also y^6 also come out with 7^3 , remaining 2xy inside the cube root.

Answer:

     x = -1          y = 2

Step-by-step explanation:

Notice that the coefficients of x are opposites of each other.  That makes the problem so much easier to solve.  All you have  to do is add the two equations and the x terms will be eliminated.

2x - 4y = -10

-2x - y = 0

    - 5y = -10

        y = 2        Substitute y = 2 into the first equation.  2x - 4(2) = -10

                                                                                          2x - 8 = -10

                                                                                               2x = -2

                                                                                                 x = -1

It is always a good idea to check your results into the equations to see if they satisfy the equations.
