Answer:

[tex]1.\ 10+x+ 8 = 18+ x[/tex]

[tex]2.\ 9(3x) = 27x[/tex]

[tex]3.\ \frac{1}{2}(10x) + 7 - 3 = 5x + 4[/tex]

[tex]4.\ -5(4x) = -20x[/tex]

[tex]5.\ 10 - 2 (8x) - 3 = 7 - 16x[/tex]

[tex]6.\ 3(7x) + 3 (-5) = 21x -15[/tex]

Step-by-step explanation:

Required

Solve each expression

[tex]1.\ 10+x+ 8[/tex]

Start by collecting like terms

[tex]10+ 8+x[/tex]

Add like terms

[tex]18+x[/tex]

The expression can't be solved further

Hence; [tex]10+x+ 8 = 18+ x[/tex]

[tex]2.\ 9(3x)[/tex]

Open the bracket

[tex]9 * 3x[/tex]

[tex]27x[/tex]

The expression can't be solved further

Hence, [tex]9(3x) = 27x[/tex]

[tex]3.\ \frac{1}{2}(10x) + 7 - 3[/tex]

Open bracket

[tex]\frac{1}{2} * 10x + 7 - 3[/tex]

[tex]5x + 7 - 3[/tex]

[tex]5x + 4[/tex]

The expression can't be solved further;

Hence, [tex]\frac{1}{2}(10x) + 7 - 3 = 5x + 4[/tex]

[tex]4.\ -5(4x)[/tex]

Open the bracket

[tex]-5 * 4x[/tex]

[tex]-20x[/tex]

The expression can't be solved further

Hence, [tex]-5(4x) = -20x[/tex]

[tex]5.\ 10 - 2 (8x) - 3[/tex]

Open Bracket

[tex]10 - 2 *8x - 3[/tex]

[tex]10 - 16x - 3[/tex]

Collect like terms

[tex]10 - 3 - 16x[/tex]

[tex]7 - 16x[/tex]

The expression can't be solved further

Hence, [tex]10 - 2 (8x) - 3 = 7 - 16x[/tex]

[tex]6.\ 3(7x) + 3 (-5)[/tex]

Open both brackets

[tex]3*7x + 3 * -5[/tex]

[tex]21x -15[/tex]

The expression can't be solved further

Hence, [tex]3(7x) + 3 (-5) = 21x -15[/tex]

Answer:

3000

Step-by-step explanation:

First find the 4 digit numbers that have all odd digits

Possible Odd digits  =5(1,3,5,7,9)  

So, total number of 4 digit numbers with odd digits can be calculated as  =5×5×5×5=625

Now find all the 4 digits numbers with at least 3 odd digits and the first digit as either 2,4,6,8 ( 0 would make it a 3 digit number)

The first digit can be 2,4,6,8

=4×5×5×5=500

Now find all the 4 digits numbers with at least 3 odd digits and the second digit as either 0,2,4,6,8

=5×5×5×5=625

Now find all the 4 digits numbers with at least 3 odd digits and the third digit as either 0,2,4,6,8

Now find all the 4 digits numbers with at least 3 odd digits and the second digit as either 0,2,4,6,8

=5×5×5×5=625

Now find all the 4 digits numbers with at least 3 odd digits and the fourth digit as either 0,2,4,6,8

=5×5×5×5=625

Add them together

625+500+625+625+625=3000

Answer:

3000

Step-by-step explanation:

4*5*5*5+5*5*5*5+5*5*5*5+5*5*5*5+5*5*5*5 = 3000

Answer:

x+1/4 + x + 2/ 3

Step-by-step explanation:

To write x+1 /4 as a fraction with a common denominator, multiply by 3/3

To write x+2/3 as a fraction with a common denominator, multiply by 4/4

Write each expression with a common denominator of 12, by multiplying each by an appropriate factor of  1

Combine the numerators over the common denominator

(x+1) x 3 + (x+2) x 4 / 12

Answer Is: 7x+ 11/ 12

Answer:

road side cabins

Step-by-step explanation:

Answer:

No, because there aren't any like terms. x and y are different variables, so therefore they can't be combined

This problem cannot be simplified, so the

answer is the same as the question.

There are no like terms.

Answer:

y - 7 = (1/10)(x - 5)

Step-by-step explanation:

Next time please share the possible answers.  Thank you.

Any line perpendicular to y = -10x + 1 has the slope +1/10, which is the negative reciprocal of -10.

Using the point-slope formula, we get:

y - 7 = (1/10)(x - 5)

Answer:

26.24 grams of total fat

Step-by-step explanation:

We can find how many grams of fat in the fries by multiplying:

64(0.41) = 26.24

The amount of grams of total fat did the French fries contain will be 26.24 grams.

The quantity of anything is stated as though it were a fraction of a hundred.

Bud’s French fries contained 41% of the daily total fat allowance for a 2,000 calorie diet.

If the recommended daily allowance of total fat for a 2,000-calorie diet is 64 grams.

Then the amount of grams of total fat did the French fries contain will be

⇒ 0.41 x 64

⇒ 26.24 grams

Step-by-step explanation:

The letters are the variables.

Options

(A) (9,0) (B) (-2,20) (C) (-5,2) (D) (0,-9)

Answer:

(B) (-2,20)

Step-by-step explanation:

Given the objective function, C=3x-4y

The vertex at which C is minimized will be the point (x,y) at which the expression gives the lowest value.

Option A

At (9,0), x=9, y=0

C=3(9)-4(0)=27-0

C=27

Option B

At (-2,20), x=-2, y=20

C=3(-2)-4(20)=-6-80

C=-86

Option C

At (-5,2), x=-5, y=2

C=3(-5)-4(2)=-15-8

C=-23

Option D

At (0,-9), x=0, y=-9

C=3(0)-4(-9)=0+36

C=36

The lowest value of C is -86. This occurs at the vertex (-2,20).

Therefore, the objective function C=3x-4y is minimized at (-2,20).

Answer:

3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, - 4) , thus

y = a(x - 2)² - 4

To find a substitute (3, - 1 ) into the equation

- 1 = a(3 - 2)² - 4 ( add 4 to both sides )

3 = a

Thus

y = 3(x - 2)2 - 4 ← equation in vertex form

   = 3(x² - 4x + 4) + 4

    = 3x² - 12x + 12 + 4

     = 3x² - 12x + 16 ← equation in standard form

with coefficient of x² term = 3

Rational exponents are quite simple really.  For instance, 2 to the power of 1/2 is the square root of two.  You take the numerator of the fraction and use that as the exponent and take the denominator and use it to root the number.  I know that sounds confusing, so I'll give a bunch of examples

2 to the power of 1/3

is the cube root of 2

2 to the power of 2/3

is the cube root of 2 to the power of 2, or the cube root of 4

2 to the power of 3/4

Is the 4th root of 2 to the power of 3, or the fourth root of 8

Answer:

The correct answer is:

[tex]g(x) = x+1[/tex]

Step-by-step explanation:

Given that:

[tex]h(x) = f\circ g(x)= \sqrt[3]{x+3}[/tex]

[tex]f(x) = \sqrt[3]{x+2}[/tex]

To find:

[tex]g(x) = ?[/tex]

Solution:

Let [tex]g(x) = m[/tex]

We have

[tex]f\circ g(x)= \sqrt[3]{x+3}\\OR\\f( g(x))= \sqrt[3]{x+3}[/tex]...... (1)

Now, we have let:

[tex]g(x) = m\\\therefore f(g(x)) = f(m)[/tex]

Putting x = in f(x), we get

[tex]f(x) = \sqrt[3]{x+2}\\\Rightarrow f(m) = \sqrt[3]{m+2}[/tex]....... (2)

Comparing equation (1) and (2):

[tex]\sqrt[3]{x+3} =\sqrt[3]{m+2}[/tex]

Taking cubes both sides:

[tex]x+3=m+2\\\Rightarrow m = x+3-2\\\Rightarrow m = x+1[/tex]

[tex]\therefore g(x) = x+1[/tex]

Hence,

The correct answer is:

[tex]g(x) = x+1[/tex]

Now,

Using Pythagorean theorem:

Hope this helps...

Good luck on your assignment..

Answer:

x = 15

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 20² = 25² , that is

x² + 400 = 625 ( subtract 400 from both sides )

x² = 225 ( take the square root of both sides )

x = [tex]\sqrt{225}[/tex] = 15

Option 4:

(4 ,1 ) ; (4*2 , 1*2) = (8 , 2) ;  (4*3 , 1*3) = (12 , 3)

Answer:

Option a

Step-by-step explanation:

This is a nice simple problem!

Given that the function f( x ) is equivalent to 3x + 400, respectively g( x ) = 5x + 200, all we are being asked to do is find their difference. Substitute the given values as such -

h( x ) = f( x ) - g( x )

⇒ h( x ) = ( 3x + 400 ) - ( 5x + 200 ) - Distribute negative sign, taking out ( )

⇒ h( x ) = 3x + 400 - 5x + 200 - Combine like elements

⇒ h( x ) = - 2x + 200

And there you have it! Our solution should be option a ( h( x ) = - 2x + 200 )

=14*4=56 Hours

Assuming that I read this correctly, Mohammad works 3 hours Monday, 3 hours Tuesday, 2 hours on Wednesday, 2 hours on Thursday and 4 hours on Friday. All you have to do is add all the hours he worked each week. So that would look like this. ->

3+3+2+2+4=14

Mohammad is working for 14 hours this week.

Since he has to know how many hours he is working this month (4 weeks) . He needs to multiply his weekly hours by 4. So 14*4 is 56.
