Step-by-step explanation:

-4x - 8 + 6 = 5 -3x - 3

-4x - 2 = -3x + 2

-x - 2 = 2

-x = 4

x = -4

For the expression 2(-2x - 4) + 6 = 5 – 3(x + 1) the value of x is -4.

Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.

The given expression is,

2(-2x - 4) + 6 = 5 - 3(x + 1)

To find the value of x, simplify the expression,

-4x - 8 + 6 = 5 - 3x - 3

-4x - 2 = 2 - 3x

-4 = 4x - 3x

x = -4

The required value of x is -4.

Step-by-step explanation:

The given parameters are;

The coordinate of A = 0

The distance from A to R which is the same as AR = 21

Given that R is on the number line, we have;

When R is on the left side of A, which is = 0 - 21 = -21, we have;

The coordinates of the midpoint, M from -21 to 0 is given as follows;

M = (A + R)/2 = (0 - 21)/2 = -10.5

When R is on the right side of A, which is = 21 - 0 = 21, we have;

The coordinates of the midpoint, M from 21 to 0 is given as follows;

Answer:

y = (-3/2)x + 7/2

Step-by-step explanation:

Find the slope of this line first.

As you move from the first point to the second, x (the 'run') increases by 6 and y (the 'rise') decreases by 4 (from 3 to -1).  Thus the slope is

m = rise/run = -6/4 or -3/2.

Find b for this situation, using y = mx + b, m = -3/2, y = -1 and x = 3:

-1 = (-3/2)(3) + b.  Multiply all three terms by 2:

2(-1) = -9 + 2b, or 7 = 2b.  Then b = 7/2, and the desired equation is

y = (-3/2)x + 7/2

Step-by-step explanation:

Answer:

Almonds = 400grams

Cashew = 300 grams

Step-by-step explanation:

Let the grams of cashew be represented by = C

the grams of almonds be represented by = A

A 700 g dry fruit pack costs ₹216 .It contains some almonds and the rest cashew kernel

C + A = 700g ......Equation 1

C = 700 - A

If almonds cost ₹288 per kg and cashew kernel cost ₹336 per kg

Let's convert them to grams

1 kg = 1000grams

For almonds

= 288/1000 = 0.288g

For cashew

= 336/1000 = 0.336g

Hence,

0.288 × A + 0.336g × C = ₹216

0.288A + 0.336C = 216

From Equation 1, substitute 700 - A for C in Equation 2

0.288A + 0.336(700 - A) = 216

0.288A + 235.2 - 0.336A = 216

Collect like terms

0.288A - 0.336A = 216 - 235.2

- 0.048A = -19.2

A = -19.2/-0.048

A = 400 grams

Substitute 400g for a in Equation 1

C + A = 700g ......Equation 1

= C + 400g = 700g

C = 700g - 400g

C = 300g

Therefore, the number of grams of Almonds = 400grams

Cashew = 300 grams

Answer:

[tex]y=-\frac{12}{7}x-\frac{80}{7}[/tex]

Step-by-step explanation:

In order to find the slope-intercept form of a line when given two points, we need to first put it into point-slope form. The point-slope form is given by the equation:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and x₁ and y₁ is one of the two points.

Anyways, let's first find the slope. Let's designate (-2,-8) as x₁ and y₁ and (-9,4) as x₂ and y₂ (it doesn't really matter). The formula for slope is:

[tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{(4)-(-8)}{(-9)-(-2)}=12/-7=-12/7[/tex]

So, the slope is -12/7.

Now, pick a point for the point-slope form. To keep things consistent, I'm going to use the point (-2,-8) as x₁ and y₁. Plug in -12/7 for m. Therefore:

[tex]y-(-8)=-\frac{12}{7}(x-(-2))\\[/tex]

Now, simplify, distribute, and isolate the y:

[tex]y+8=-\frac{12}{7}(x+2)\\y+8=-\frac{12}{7}x-\frac{24}{7}\\y=-\frac{12}{7}x-\frac{24}{7}-8\\y=-\frac{12}{7}x-\frac{24}{7}-\frac{56}{7} \\y=-\frac{12}{7}x-\frac{80}{7}\\y=-\frac{12}{7}x-\frac{80}{7}[/tex]

Answer: 12.25miles.

Step-by-step explanation:

This is a simple proportion.

                       20 miles   = 3.5miles

      ∴                1 mile     = 3.5/20

      ∴  1hour 10minutes  which is equivalent to 70minutes will be

                                        =  (3.5/20 x ⁷⁰/₁ ) miles

                                        = 12.25miles

x < -3 or x > 1

=====================================================

Work Shown:

Solve the first inequality for x

3x+2 < -7

3x < -7-2 .... subtract 2 from both sides

3x < -9

x < -9/3 .... divide both sides by 3

x < -3

Do the same for the second inequality

-4x+5 < 1

-4x < 1-5

-4x < -4

x > -4/(-4) .... note the inequality sign flips

x > 1

So either x < -3 or x > 1. This points to choice A as the answer.

Answer: 8 liters  can.

Step-by-step explanation:

First we need to find the volume of the cart tank . Since it is in the shape of a rectangular prism we have to multiply the length by the width by the height to find the volume.

V= 40 * 25 * 8  

V =  8000  

Which means that the volume is 8000 cubic centimeters.  

Now convert 8000 cubic centimeters to liter.

It gives us a hint that 1 liter is equal to 1000 cm^3

So to convert 8000 cubic centimeters to liters we will have to divide it by 1000.

8000/1000 = 8 liters.

Answer:

y = 6

Step-by-step explanation:

Given a parallelogram ABCD with diagonals AC and BD.

Kindly refer to the diagram attached for the given parallelogram.

[tex]AE=2x\\BE=y+10\\CE=x+2\\DE=4y-8[/tex]

To find:

The value of y = ?

Solution:

First of all, let us consider a property of parallelogram and its diagonals.

The intersecting point of diagonals of a parallelogram bisect the diagonals in two equal parts.

Let us consider the given parallelogram ABCD which has its diagonals BD and AC intersecting at point E.

As per the property stated above:

AE = CE and

DE = BE

Putting the values of AE, CE, DE and BE as given in the question statement and solving for [tex]x[/tex] and [tex]y[/tex]:

[tex]2x = x+2\\\Rightarrow \bold{x = 2}[/tex]

and

[tex]y+10=4y-8\\\Rightarrow 4y-y = 10+8\\\Rightarrow 3y=18\\\Rightarrow y =\dfrac{18}{3}\\\Rightarrow \bold{y= 6}[/tex]

So, the answer is:

y = 6

Answer: Plane

Step-by-step explanation: A plane is a flat surface that has no thickness.

Think of a plane as a wall or a floor of a room.

Another important characteristic of a plane is that it has no edges.

So it extends forever in all directions.

First multiply the numbers inside the radicals together.

So √3 · √15 is √45.

So we have 2√45.

Note that the 2 can't be multiplied by anything since

√15 has nothing outside of the radical.

So we have 2√45.

Now, break down your square root.

√45 breaks down as 9 · 5 and 9 breaks down as 3 · 3.

Since we have a pair of 3's, a 3 comes outside of the radical

multiplying by the 2 that was previously outside to get 6.

The 5 doesn't pair up so it stays inside.

So our final answer is 6√5.

Answer:

C) [tex]6\sqrt{5}[/tex]

Arithmetic without explanation:

[tex]2\sqrt{3}* \sqrt{15}\\ = 2\sqrt{3}* \sqrt{3*5} \\ = 2\sqrt{3^2} *\sqrt{5} \\ = 2 * 3\sqrt{5} \\= 6\sqrt{5}[/tex]

Example of radical multiplication:

Take [tex]y\sqrt{x} * a\sqrt{b}[/tex]  as an example:

1. Multiple the numbers inside the roots

      [tex]\sqrt{x} * \sqrt{b} = \sqrt{x*b} = \sqrt{xb}[/tex]  

2. Multiple the numbers outside the roots

       [tex]y*a = ya[/tex]

3. Combine them and simplify

      [tex]ya\sqrt{xb}[/tex]

Step-by-step explanation:

We are given the expression [tex]2\sqrt{3}*\sqrt{15}[/tex]

 1. Identify the roots and multiply them

         The roots are [tex]\sqrt{3}[/tex]  and [tex]\sqrt{15}[/tex]

           [tex]\sqrt{3} *\sqrt{15} \\= \sqrt{45}[/tex]

  2. Multiply the numbers outside the root

         For [tex]2\sqrt{3}[/tex] it is [tex]2[/tex] and for [tex]\sqrt{15}[/tex] it is [tex]1[/tex]

          [tex]2*1 = 2[/tex]

  3. Combine and simplify

    Combine:

              [tex]2* \sqrt{45}\\= 2\sqrt{45}[/tex]

   Simplify:

           *Note: [tex]\sqrt{n^2} = n[/tex]

        1. Find the Prime factorization of 45

                   [tex]45 = 3^2 * 5[/tex]

        2. Simplify the Root

                  [tex]2\sqrt{45} \\ = 2\sqrt{3^2 * 5} \\= 2\sqrt{3^2} * \sqrt{5} \\= 2 * 3\sqrt{5}\\ =6\sqrt{5}[/tex]

We end up with [tex]6\sqrt{5}[/tex]

Answer: y < (-1/4)*x + 1.

Step-by-step explanation:

The first thing you need to notice is that the line is not solid and that the shaded part is under the line, so our inequality will be strictly smaller than a linear equation.

y < a*x + b.

Now let's find the equation of the line.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In the graph, we can see that the line passes through the points: (0,1) and (4. 0)

Then the slope is:

a = (0 - 1)/(4 -0) = -1/4.

Now we know that the line is:

y = (-1/4)*x + b

To find the value of b, just replace the value of one of the points in the equation.

We know that (0,1) is a solution of the equation (x= 0, y = 1)

1 = (-1/4)*0 + b = b

1 = b

Then our inequality is:

y < (-1/4)*x + 1.
