Answer:

27

Step-by-step explanation:

if p is 27 and 27 /3 =9 and 9-5=4 that means the answer is 27

Answer: yea its 27

Step-by-step explanation:

The simplified answer is 5p - 1.25p²

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.

Given:

2.5p(2 - 0.5p)

Now solving further

2.5p * 2 - 2.5p (0.5p)

5p - 1.25p²

Hence, the simplified answer is 5p - 1.25p².

The given expression would be simplified by solving for the negative exponent.

In this expression, the base term is 3x^2/3 and the exponent is -1.

A positive exponent tells us how many times a number is multiplied by itself while the negative exponent tells us how many times the base number has to be divided. It can also be described as the number of times the reciprocal of the base number is multiplied by itself.

The negative exponent rule states that: a^-x=1/a^x

Hence, applying the rule:

(3x^²/₃)^-1=1/(3x^²/₃)^1

Multiplying the power and simplifying,

1/(3x^²/₃)^1=1/3^1x^²/₃*1=1/3x^²/₃

The simplest form of the expression (3x^²/₃)^-1 is 1/3x^²/₃.

To graph a linear equation, including the function y + 4 = 5 · x, we needed to rewrite the equation into its explicit form, mark two distinct points on a Cartesian plane and pass a line through them. The result is presented in the image attached below.

Herein we find a linear equation in a non-canonical form and to which we are asked to graph. According to geometry, lines can be created by knowing the location of two distinct points on Cartesian plane. The detailed procedure is now shown.

First, clear the variable y to obtain the explicit form of the linear equation:

y = 5 · x + 4

Second, look up for two distinct points on Cartesian plane by evaluating the expression at distinct values of x:

x = 0

y = 5 · 0 + 4

y = 4

x = 1

y = 5 · 1 + 4

y = 9

The points (0, 4) and (1, 9) lie on the line.

Third, mark the coordinates of the two points and pass a line through them.

The 4th Option

Step-by-step explanation:

For a graph to be a function, it must not be broken up at any point (as in Option 3) and there can be no points that overlap each other vertically (as in Options 1 and 2). So, the only option that is continuous and with no overlapping points is Option 4.

The equation model the situation is mathematically given as

(0.5x + 7.5) = 0.75(x + 6)

This is further explained below.

Generally, the  cost of the beads in a necklace is  mathematically given as

0.50x + 6*1.25 = 0.5x + 7.5 dollars

Therefore

There are a total of x + 6 beads. Due to the fact that 0.75 is the typical cost of the beads,

[tex]\frac{0.5 x+7.5}{x+6}=0.75[/tex]

0.5 x+7.5=0.75(x+6)

In conclusion, The solution for x may be obtained as follows:

0.5x + 7.5 = 0.75x + 4.5

-0.25x = -3

x = -3/-0.25

Days it took the grass to grow 1 centimeter and  centimeters the grass grew in 1 day

0.625 days to grow 1 cm.

16/10 = 1.6 cm in 1 day.

According to the law of proportion, any two ratios or fractions must be equal.

In only a week and a half, the grass in Jamie's backyard grew by 16 cm. it is expanding at an unchanging pace.

We need to determine how many days have passed since the grass has grown one centimeter.

Let's say that x represents the number of days that the grass grew one centimeter.

Given the following definition of proportion:

16/10=1/x

16x = 10

x = 0.625 days

As a result, one centimeter of grass growth occurred after 0.625 days had passed.

Therefore, the two points on the line are:

To find the equation of the line when given two points from the line, first find the slope:

[tex]\textsf{slope}\:(m)=\dfrac{\textsf{change in $y$}}{\textsf{change in $x$}}=\dfrac{-4-0}{-1-1}=2[/tex]
