Answers

Answer:

x+2y=0

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=-1/2(x-4)

y+2=-1/2x+4/2

y+2=-1/2x+2

y-(-1/2x)=2-2

y+1/2x=0

1/2x+y=0

2(1/2x+y)=2(0)

x+2y=0

Three less than a number is 14 more than 2 times that number. What is the number?

Answers

Answer:

-20 = - 20

Step-by-step explanation:

Suppose the number is x

three less than a number means x - 3 which is equal to 14 more than twice a number means 2x +14.

So we can write

x - 3 = 2x +14 - - - - - A

subtract x from both sides

x - x - 3 = 2x - x +14

-3 = x +14

Subtract 14 from both sides

-3 - 14 = x +14 - 14

-17 = x

Or x = - 17

Now can verify our answer by putting the value of x in Eq A

-17 - 3 = 2 x (-17) +14

-20 = - 34 +14

-20 = - 20

I hope this helps.       :)

Hey There! Allow me to explain how to solve this (I will not say the answer bc I also don't know but here is how you can find it). As you see the shape is a Cyclinder & the formula for it is V=Bh or V=πr2h. You might wanna start with solving the problems (8x - 4) & (11x + 12) Use the order of PEMDAS (Parrenthesis, Exponets, Multiplication, Division, Addition, Subtraction.) to solve is so if solving (8x - 4) And if x = 8 than first begin with mutiliplying 8 x 8 (Because it says 8x and x = 8 which means we are multiplying) than subtract that with 4 (Which will be 64 - 4). Than for (11x + 12) you will wanna do 11 x 8 which is 88 added by 12 which that will be 100. Than use the formula (V=Bh or V=πr2h) And you should have you're answer! I hoped this help and sorry for not finding the answer but atleast I explained to you on how to solve it! <3

A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 6800 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine xxx, the number of 100-kilogram crates that can be loaded into the shipping container.

Answers

Answer:

x ≤ 207 crates

Step-by-step explanation:

Greatest weight of the container = 27,500 kilograms

Weight of other shipment = 6,800 kilograms

Weight of a crate = 100 kilograms

Number of 100-kilogram crates that can be loaded into the shipping container = x

The inequality is

27,500 ≤ 6800 + 100x

27,500 - 6800 ≤ 100x

20,700 ≤ 100x

x ≤ 20,700 / 100

x ≤ 207 crates

Answer:

∠ V = 130°

Step-by-step explanation:

In a parallelogram opposite angles are congruent and consecutive angles are supplementary.

∠ S and ∠ V are not opposite angles, they are consecutive, then

∠ S + ∠ V = 180°

50° + ∠ V = 180° ( subtract 50° from both sides )

∠ V = 130°

x + 320 = 360

x            =  40

Answer:

x=40

Step-by-step explanation:

So, since the figure has 4 sides, we know that the sum of the interior angles is 360. To check: (n-2)*180=(4-2)*180=28180=360.

That means x equals 360 minus the sum of the other three angles.

100+120+100=320

360-320=40

x=40 degrees

3 people invest in a business in the ratio 2:3:5.if the profit from the business is $450 000.how much does each person get?​

Answers

Each person gets 45,000

Answer:

$90,000;$135,000;$225,000

Step-by-step explanation:

In this question we have to find the share of each person

First we have to find the sum of all the ratios,

[tex]2 + 3 + 5 \\ = 10[/tex]

Then we have to represent their share as a fraction and then multiply it by the total value,

The share of first person:-

[tex] \frac{2}{10} \times 450000 \\ = 2 \times 45000 \\ = 90000[/tex]

So the first person share is $90,000

The share of second person:-

[tex] \frac{3}{10} \times 450000 \\ = 3 \times 45000 \\ = 135000[/tex]

So the second person share is $135,000

The share of third person:-

[tex] = 450000 - (135000 + 90000) \\ = 450000 - 225000 \\ = 225000[/tex]

So the third person share is $225,000

(This is your answer hope it helps :))

A. 3.077 g

B. 3.0775 g

C. 3.078 g

D. 3.75 g

Answers

Answer:

C. 3.078

Step-by-step explanation:

14.1005 - 11.023 = 3.0775

Then you round the ten thousands place turning 75 into 8 equaling 3.078

Subtraction is a mathematical operation. The amount of silver lab group A got compared to lab group B is 3.0775 gm more.

What is subtraction?

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

The amount of silver that group A got is 14.1005gm, while the amount of silver that group B got is 11.023 grams. Therefore, the amount of silver lab group A got compared to lab group B is,

14.1005 gm - 11.023 gm = 3.0775 gm

Hence, the amount of silver lab group A got compared to lab group B is 3.0775 gm more.

a. y=-2.5x+50

b. slope=-2.5. y-intercept=50

Answer:

slope is -2.5

y-intercept is (0,50)

slope y-intercept is y= -2.5x + 50

Step-by-step explanation:

to find the slope you use rise/run the rise is 5 and the run is -2 which is 5/-2 or -2.5

the y-intercept is where the line hits a perfect point on the y-axis which would be at 50 in your case

y=mx+b

m= slope and b= y-intercept

why is m the slope? because the slope is the unknown variable

Answer:

b. y = x + 4

Step-by-step explanation:

So we know at x = 0, or the middle black line, the red line is touching 4 so y = 4. 4 is the y intercept so the equation should say "+ 4"

Then, we can see that when the red line increases up by 1 value, it also increases 1 value to the right so that would be 1/1 which equals to 1x.

Therefore the correct answer is y = x + 4
