-x^2+2x-5^3-4x+5 in standard form

Answer:

2.1

Step-by-step explanation:

6/7 ( 3/8 ÷ 1.5 + 2 1/5 )

Solve for brackets first.

6/7 ( 0.375/1.5 + 2.2 )

Divide the two terms in the brackets.

6/7 (0.25+2.2)

Add the two terms in the brackets.

6/7 (2.45)

Multiply the two terms.

= 2.1

Answer:

[tex]2\frac{1}{10}[/tex]

Step-by-step explanation:

Use BIDMAS

B = Brackets

I = Indices

D = Division

M = Multiplication

A = Addition

S = Subtraction

[tex]\frac{6}{7} * (\frac{3}{8} /\frac{15}{10} +2\frac{1}{5} )[/tex]

→ Work out the division sum inside of the brackets

[tex]\frac{3}{8} /\frac{15}{10} =\frac{3}{8} *\frac{10}{15} =\frac{30}{120} =\frac{1}{4}[/tex]

→ Write out new sum

[tex]\frac{6}{7} *(\frac{1}{4} +2\frac{1}{5} )[/tex]

→ Work out the sum of the addition inside the bracket

[tex]\frac{1}{4} +2\frac{1}{5} =\frac{1}{4} +\frac{11}{5} =\frac{5}{20} +\frac{44}{20 } =\frac{49}{20} =2\frac{9}{20}[/tex]

→ Write out new sum

[tex]\frac{6}{7} *2\frac{9}{20}[/tex]

→ Solve

[tex]\frac{6}{7} *2\frac{9}{20}=\frac{6}{7} *\frac{49}{20} =\frac{294}{140} =\frac{147}{70} = \frac{21}{10} =2\frac{1}{10}[/tex]

Answer:

Step-by-step explanation:

[tex]F\left[X] = 5X +7X -2 =12X-2\\[/tex]

[tex]g\left[x] = -2x^2+4x+5 \\[/tex]

[tex]f(x) - g(x) \\= 12x -2 - ( -2x^2+4x+5)\\=12x-2+2x^2-4x-5\\=2x^2 + 8x -7[/tex]

Answer:

2x^2+8x-7

Step-by-step explanation:

Combine like terms 5x+7x in your f(x) equation.  

f(x) = 12x-2 then subtract g(x) from f(x).

12x-2-(-2x^2+4x+5)

Now distribute the negative to everything in the parenthses to change the signs.

12x-2+2x^2-4x-5.

Now, combine like terms.  12x-4x=8x

Combine -2-5=-7

Next, order expression beginning with largest exponent:

Your answer:  2x^2+8x-7.

Answer:

A, E and F

Step-by-step explanation:

All three of them equal root 5.

Answer:

Step-by-step explanation:

3c + 5w = 16

6c + 2w = 22

-6c - 10w = -32

6c  + 2w = 22

-8w = -10

w = 10/8 = 5/4 = $1.25 per lb

3c + 5(1.25) = 16

3c + 6.25 = 16

3c = 9.75

c = $3.25 per lb

Answer:

Rhombus

Step-by-step explanation:

In a rhombus, all sides are equal and opposite sides are parallel. Opposite angles are equal.

The shape given in the figure describes Rhombus.

We have given a diagram

We have to find the correct option.

The Rhombus is a quadrilateral with equal sides.

Since opposite sides of a parallelogram are equal so,the rhombus is a special type of a parallelogram whose all sides are equal.

In a rhombus, all sides are equal and opposite sides are parallel. Opposite angles are equal.

Therefore the correct option is C.

Answer:

Sarra watched 80% of the show.

Step-by-step explanation:

12÷15×100

Answer:

80%

Step-by-step explanation:

You have to take the total number of TV show episodes and divide it by the amount the person watched, in this case 15/12. Next, you have to multiply the answer you get by 100, in this case 0.8*100, this leads you to move the decimal point two places to the right giving you 80%.

Answer:

y=27 when x=2

Step-by-step explanation:

y varies inversely as the cube of x

y=k(1/X^3)

y=1 when x=6

y=k(1/X^3)

1=k(1/6^3)

1=k(1/216)

k=1÷1/216

K=1×216/1

k=216

find y when x=2

y=k(1/X^3)

y=216(1/2^3)

y=216(1/8)

y=216/8

y=27

Answer:

2.27 m²

Step-by-step explanation:

The shaded area is the subtraction of the area of an equilateral triangle (with sides = 2 m) to the area of a square (with sides = 2 m)

Area of equilateral triangle = √3/4*a²

where a is the length of the sides of the triangle. Replacing with a = 2

Area of the equilateral triangle = √3/4*2² = √3 m²

Area of the square = a² = 2² = 4 m²

Shaded area = 4 - √3 ≈ 2.27 m²

Answer:

The distance formula

Step-by-step explanation:

This was kind of vague, but I'll try my best.

You can use the distance formula! It is basically the pythagorean theorem.

Here's the steps,

1. draw a right triangle from the corners. If you have graph paper, this should be relatively easy.

2. locate the hypotenuse, that is the distance.

3. next use the pythagorean theorem/ distance formula (same thing)

4. Except, instead of a and b and c, replace them with

(Change in x)²+(change in y)²= distance²

Now plug in the values

Now you're done!

Answer:  45 degrees.

Step-by-step explanation:

The middle angle of a right angle is  90 degrees and half of the 90 degrees is 45.

Answer:

Step-by-step explanation:

let the middle angle=x

then

[tex]x+\frac{x}{2}+90=180\\2x+x+180=360\\3x=360-180=180\\x=180/3=60\\\frac{x}{2}=30[/tex]

so angles are 30°,60°,90°

Answer:

y+1 = -1(x+10)

Step-by-step explanation:

The point slope equation of a line is

y-y1 = m(x-x1) where m is the slope  and (x1, y1) is a point on the line

y - -1 = -1 (x --10)

y+1 = -1(x+10)

Step-by-step explanation:

Answer:

7x - y = 5

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Obtain the equation in point- slope form and rearrange into standard form.

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 7 and (a, b) = (1, 2)

y - 2 = 7(x - 1) ← in point- slope form

y - 2 = 7x - 7 ( subtract y from both sides )

- 2 = 7x - y - 7 ( add 7 to both sides )

5 = 7x - y , that is

7x - y = 5 ← in standard form

Answer:

Hai

6x=3600

x=600

so tuan collected 600 bottles.

aziz collected 3000 bottles.

5x(aziz)+x(tuan)=3600

good luck (:

Answer:

Step-by-step explanation:

Let x represent the number of bottles Tuan collected. Then 5x is the number Aziz collected. Their total is ...

  x +5x = 3600

  6x = 3600 . . . . . . collect terms

  x = 3600 ÷ 6

  x = 600

Tuan collected 600 bottles.
