Determine whether the graph table or equation represents a linear nonlinear function.

Y=x(x+3)

Answer:

y = 9x + 9

Step-by-step explanation:

so the points are:

(0,9) (1, 18) (2, 27) (3, 36) (4, 45)

since the y intercept is when x is 0 write it in the equation!

y = mx + 9

now to solve for slope

use the equation y2 - y1/ x2 - x1 or y1 - y2/x1 - x2

sooo use (1, 18) and (2, 27)

27 - 18/2 - 1

9 / 1 = 9

y = 9x + 9

check with the points you did not use!

(3, 36)

36 = 9(3) + 9 ?

36 = 27 + 9?

36 = 36

Answer:

each side of the square is 25cm

Step-by-step explanation:

this is because of two things:

1. a square has equal sides

2. the perimeter is all the sides added together.

so if you call the length of one side x, you can make this equation:

x + x + x + x = 100

combine like terms

4x = 100

divide both sides by 4

x = 100/4

x = 25

Answer:

25 cm

Equivalent expressions are expressions that have the same value.

The equivalent expression of [tex]3m + 1[/tex] is [tex]2 + m - 1 + m[/tex]

From the complete question, the expression is given as:

[tex]3m+1-m[/tex]

Collect like terms

[tex]3m+1-m = 3m - m + 1[/tex]

Evaluate like terms

[tex]3m+1-m = 2m + 1[/tex]

Express 2m as m + m

[tex]3m+1-m = m + m + 1[/tex]

Express 1 as 2 - 1

[tex]3m+1-m = m + m +2 - 1[/tex]

Rewrite the expression as:

[tex]3m + 1 = 2 + m - 1 + m[/tex]

Hence, the equivalent expression of [tex]3m + 1[/tex] is [tex]2 + m - 1 + m[/tex]

Answer:

18.4 cm

Step-by-step explanation:

A square has equal sides.  Let's say one side is x.  The area would be x^2.  We know the area to be 169 cm^2, so:

x^2 = 169 cm^2

x = 13 cm

The diagonal, z,  would form a right triangle with two sides of length 13 cm.  The Pythagorean theorem can be used:

13^2 + 13^2 = z^2

z^2 = 338

z = 18.38 cm, or 18.4 cm

Answer:

X= -8

Step-by-step explanation:

1. -18x+24=168

2. -18x=168-24

3. -18x=144

4. x = -8

Answer:

x = -8

Step-by-step explanation:

-3(6x-8) = 168 (Distribute -3 t0 6x and -8)

-18x + 24 = 168 (subtract 24 on both sides)

-18x = 144 (divide by -18 on both sides)

x = -8

where I is the simple interest

           p is the principal

           r is the percentage rate

          t is the duration

Simple interest accrues on the principal of either a loan or an investment. This amount is payable after a duration of time.

Principal is the amount borrowed or invested in a business

Rate is the percentage commission to be paid on the amount borrowed

Time is the duration of the borrowing.

Step-by-step explanation:

The given expression 250m³ +54 can be written in the form, 2(5m + 3)(5m² - 15m + 3²)

An expression is a sentence with at least two numbers or variables having mathematical operation. Maths operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

The expression, 250m³ +54

⇒ 250m³ +54

It can be written as,

⇒ 2×125×m³ +  2×27

Now, 2 can take common

⇒ 2(125×m³ + 27 )

⇒  2(5³×m³ + 3³ )

⇒  2(5m³ +  3³ )

It is known that, it is like algebraic identity

a³ + b³  =  (a + b)(a² - ab + b²)

Similarly, given expression can be written in form of identity

2(5m³ +  3³ ) = 2(5m + 3)(5m² - 15m + 3²)

Hence, it can be expressed as 2(5m + 3)(5m² - 15m + 3²)

The difference between the median of the golf pro box and tennis pro box is 20.

The median is the middle value of an entire data set. If the number of data points(observations) in the set is odd then the middle value is the median but, for an even number of observations, the median is calculated by finding the means for the two middle data points.

As we know that the vertical line in the box plot is the median. Therefore, the median of the Golf pro shop is 40, while the median of the tennis pro shop is 20.

The difference between the median of the golf pro box and tennis pro box

= 40 - 20

= 20

Hence, the difference between the median of the golf pro box and tennis pro box is 20.
