-7x - 2y = 14
6x + 6y = 18

Answers

Answer 1

Answer:

x=-4, y=7

Step-by-step explanation:

Answer 2

Answers : x = (15/6), y =

(1/2).

Step-by-step explanation:

Explanation: To solve this equation through elimination, you need to isolate one of the variable. You can isolate the y variable since the x variables can be subtracted and go away. Add the two equations to get rid of one variable. (6x + 6y = 18) + (-6 + 2y = -14) = (8y = 4). Now you need to solve for y. y = 4/8, y = 1/2. Now, plug the y back into one equation and solve for x. 6x + 6(1/2) = 18. 6x + 3 = 18. 6x = 15. x = 15/6. Plug the two answers back in to the equation to check your answers. 6(15/6) + 6(1/2) = 18, 15 + 3 = 18. -6(15/6) + 2(1/2) = -14, -15 + 1 = -14.

Answers

Answer: 300π

Step-by-step explanation: Volume=(pi)(radius^2)(height)

Volume=(pi)(5^2)(12)

V=(pi)(25)(12)

V=(pi)(300)

The volume of the given cylinder is equal to 300π.

What is volume?

Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write volume as -

V = ∫∫∫ F(x, y, z) dx dy dz

Given is to find the volume of the cylinder shown in the image.

The volume of cylinder is given by -

V = πR²h

Here, the radius of the cylinder base is 5 units. The height of the cylinder

is 12 units. So, we can write the volume as -

V = π x 5 x 5 x 12

V = 300π

Therefore, the volume of the given cylinder is equal to 300π.

Answer:

2. B. 30 sq yd

Step-by-step explanation:

[tex]area = area \: of \: triangle \: + \: area \: of \: parallelogram \\ but \: area \: of \: parallelogram = area \: of \: rectangle - area \: of \: two \: small \: triangles \\ = (4 \times 8) - 2( \frac{1}{2} \times 3 \times 4) \\ = 32- 12 \\ = 20 \: sq \: yards \\ area = (\frac{1}{2} \times 5 \times 4) + 8 \\ = 10 + 20 \\ = 30 \: sq \: yards[/tex]

Answer:

The area of shaded figure is 30 sq yards .

Step-by-step explanation:

In the graph the figure is consist of :

Many grid square and each square grid is equals one square yards . Two shapes which are parallelogram and triangle .

To calculate the area of shaded figure we need to find the area of triangle and parallelogram and combine them to get the area of shaded figure.

Finding the area of triangle:-

Area of triangle = ½ × Base × Height

substitute the values and solve;

Area of triangle = ½ × 5 × 4

Area of triangle = ½ × 20 yard²

Hence, the area of triangle is 10 sq yards.

Finding the area of parallelogram :

Here, to calculate the area subtract the area of two small circle from the area of rectangle .

Area of parallelogram = l × b - 2 (( b × h )½)

Substitute the values we get,

Area of parallelogram = 4 × 8 - 2 ( 3 × 4 × ½)

Solve it ;

Area of parallelogram = 32 - 12.

Substitute 12 from 32 .

Area of parallelogram = 20 sq yards.

Hence, Area of parallelogram = 20 sq yards.

Finding the area of shaded figure.

Area of figure = Area of parallelogram + Area of triangle.

Area of figure = 20 sq yards + 10 sq yards.

Add 20 sq yards and 30 sq yards.

Area of figure = 30 sq yards .

Hence,

The area of shaded figure is 30 sq yards .

Step-by-step explanation:

I can't see the words on your image very well but I can give you an explanation of the remainder theorem.

The theorem allows you to find the remainder of a division without doing the division itself.

You can find the remainder when  a polynomial is divided by a linear expression like 3x - 2, for example,  using this theorem.

An example will explain the method:

What is the remainder when x^3 - x^2 - 2x - 5 is divided by 2x - 1?

Put 2x - 1 = 0, this gives x = 0.5.

Now we plug x = 0.5 into the polynomial:

This = (0.5)^3 - (0.5)^2 -2(0.5) - 5 = -6.125

So the remainder is -6.125.

The formal definition is

The remainder when P(x) is divided by x - a is f(a).

Jeevan buys a bike for Rs 200000. At the end of 1 year, the value of the bike has depreciated by 15 percent.How much is the bike now worth?​

Answers

Answer:

Rs.170000

Step-by-step explanation:

Given data

Cost price of bike= Rs 200000

Time= 1 year

Rate of depreciation= 15%

Let us apply the formula for depreciation

A=P(1-r)^t

A= 200000(1-0.15)^1

A= 200000(0.85)^1

A= 200000*(0.85)^1

A= 200000*(0.85)

A=Rs.170000

Hence the value of the bike will be Rs.170000

Answers

Answer:

Number of servings in 13 cups strawberries = 39

Step-by-step explanation:

Total amount of strawberries Kelly has = 13 cups

Amount of strawberries Kelly used in one serving = [tex]\frac{1}{3}[/tex] cups

Number of servings in 13 cups of strawberries = [tex]\frac{\text{Total amount of strawberries with Kelly}}{\text{Strawberries required in one serving}}[/tex]

= [tex]\frac{13}{\frac{1}{3}}[/tex]

= [tex]13\times \frac{13}{1}[/tex]

The triangle shown is a right triangle. I am assuming that the 'x' is the missing angle measurement.

The three angle measures in a triangle add up to 180 degrees.

[tex]60 + 90 = 150\\\\180 - 150 = 30[/tex]

The third angle should measure 30 degrees.

Hope this helps.

Answer:

30 degree

Step-by-step explanation:

60+90+x = 180 ( Angle sum property of a triangle )

150+x =180

x = 180-150

x = 30

therefore x is 30 degree
