Answer:

x = 7

Step-by-step explanation:

Let x be the number

x+16 = 23

Subtract 16 from each side

x+16-16 =23-16

x = 7

Answer:

(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)

Step-by-step explanation:

Given

(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²)

Thus

(a + b)³ + 8c³

= (a + b)³ + (2c)³

= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )

= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)

Answer:

The first term is 3. The common difference is 2.

Step-by-step explanation:

The first term is x.

The common difference is d.

The second term is x + d.

3rd term: x + 2d

4th term: x + 3d

7th term: x + 6d

"The fourth term of an Arithmetic Sequence is equal to 3 times the first term"

x + 3d = 3 * x       Eq. 1

"the seventh term exceeds twice the third term by 1"

x + 6d = 2(x + 2d) + 1       Eq. 2

Simplify Eq. 1:

2x = 3d

Simplify Eq. 2:

x + 6d = 2x + 4d + 1

x = 2d - 1

Multiply both sides of the last equation by 2.

2x = 4d - 2

2x = 3d   (simplified Eq. 1)

Since 2x = 2x, then the right sides are equal.

3d = 4d - 2

d = 2

2x = 3d

2x = 3(2)

2x = 6

x = 3

Answer: The first term is 3. The common difference is 2.

When it comes to scannable resumes, it is not recommended that you b. Use special characters like italics and underlining.

Because they are to be scannable, they are not to have complicated characters that might be unscannable such as special characters and underlining.

They should be printed on white paper using black ink only and should have a format that is best described as being neat and clean.

Answer:

The number of sides is 7

Step-by-step explanation:

Once the sum of interior angles is equal to 900º and the sum of interior angles is given by

[tex]S=(n-2) \cdot 180\º, \text{ as }n \text{ being the number of sides}[/tex]

[tex]900\º = (n-2) \cdot 180\º[/tex]

Answer:

a. 20x > 10x + 80

b.  •20x > 10x + 80

• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x

• Simplify: 10x > 80

• Divide both sides by 10:   10x/10 > 80/10

• Simplify: x > 8

Step-by-step explanation:

10x + 80 = number of seashells Pilar has.

20x = number of seashells Marisol has.  

answer for a:  20x > 10x + 80

answer for b: 20x > 10x + 80

• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x

• Simplify: 10x > 80

• Divide both sides by 10:   10x/10 > 80/10

• Simplify: x > 8

Answer:

mechanical pencil costs $1.25 each

Step-by-step explanation:

First, lets define our variables:

notebook = n

mechanical pencil = p

Next, we need to set up two equations using the information given:

n + 3p = 4.75

2n + p = 3.25

Next, lets take the first equation and solve for n.

n+ 3p = 4.75

n = 4.75 - 3p

Now we can replace "n" in the second equation with "4.75 - 3p".

2n + p = 3.25

2(4.75 - 3p) + p =3.25

9.5 - 6p + p = 3.25

9.5 - 5 p = 3.25

9.5 = 5p + 3.25

5p = 6.25

p = 1.25

Finally, we can go a step further and solve for "n" by plugging "p" back into the second formula:

n = 4.75 - 3(1.25)

n = 1.0

I hope this helps!

Answer: 9

Step-by-step explanation:

Let the consecutive odd numbers be y, y+2 and y+4.

Five times the smallest of three consecutive odd integers is seven more than twice the largest. Find the largest integer can be expressed as:

5y = 2(y+4) + 7

5y = 2y + 8 + 7

5y = 2y + 15

5y - 2y = 15

y = 3

The smallest odd number is 5

The largest integer will be:

= y + 4

= 5+4

= 9

Answer:

1) Function

2) Function

3) Not a Function

Step-by-step explanation:

Using the vertical line test, using a pen, pencil or finger to move it vertically, I determined that 2 of the 3 questions was a function because the last question would not be a function since there are two lines instead of one when doing the test. Hope this helps!

Graph A:

It is a function.

Graph B:

It is a function.

Graph C:

It is not a function.

We have,

Vertical line test:

If every vertical line intersects the graph at most once, meaning that no two different points on the graph lie on the same vertical line, then the graph represents a function.

Now,

Graph A:

Any vertical line will touch only once on the graph.

It is a function.

Graph B:

Any vertical line will touch only once on the graph.

It is a function.

Graph C:

Any vertical line will touch more than once on the graph.

It is not a function.

Thus,

4) (-4,-3)

Step-by-step explanation:

1)

Subtract  y  from both sides of the equation.

x  =  8  −  y

x  −  y  =  −2

Replace all occurrences of x  in x  −  y  =  −2  with  8  −  y.

x  =  8  −  y

(8  −  y)  −  y  =  −2

Subtract y from  −y.

x  =  8  − y

8  −  2y  =  −2

Solve for  y  in the second equation.

x  =  8  −  y  

y  = 5

Replace all occurrences of  y  in  x  =  8  −  y  with  5.

x  =  8  −(5)

y  =  5

Simplify  8  −(5).
