Is the given value a solution to the equation?

4n − 3 = −2n + 9

n = 2

Answers

Yes 8-3=-4+9. 8-3=5. -4+9=5

Yes, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.

Given is the equation -

4n − 3 = −2n + 9

We have -

4n − 3 = −2n + 9

For n = 2, we can write -

4 x 2 - 3 = - 2 x 2 + 9

8 - 3 = 9 - 4

5 = 5

So, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Therefore, yes, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Step-by-step explanation:

Circumference = 2pi(r)

26.5 / 2 = 13.25 (radius)

2pi(13.25) = 83.25 (circumference of the full circle)

83.25 / 2 = 41.625 or 41.63

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation
F=9/5 C+32
1.In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?

2.In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?

3.There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.

Answers

1 is 122
2 is -51.1111F
3 is F=9/5c+32

The temperatures are in 50° Celsius, -60° Celsius and -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.

What is the temperature?

Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.

Given, the conversion expression of degrees Fahrenheit to degree Celsius.

The expression is,

F = (9/5)C + 32

For the option 1,

C = 50° Celsius

Then F = 9 x 50/5 + 32

= 90 +32

= 122° Fahrenheit

For the option 2,

C = -60° Celsius

Then F = 9 x -60/5 + 32

= -108 + 32

= -76° Fahrenheit

For the option 3,

C = F

Then F = 9F / 5 +32

F - 9F/5 = 32

-4F / 5 = 32

F = -160/4

F = -40° Celsius.

Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and -40° Celsius respectively.

Answer:

y-intercept: (0,4)

Slope: -1/3

Step-by-step explanation:

y-intercept: (The y-axis is the vertical axis.) this is where the line crosses the y-axis. (This always occurs when x = 0.) From the graph, the purple line crosses the y-axis at 4 therefore: y-intercept = (0,4)

slope:

slope = rise / run

this means slope = y/x

first step is to locate to places along the purple line that cross the grid boxes neatly. this occurs at (-3,5), (0,4), and (3,3).

Taking any two of the three intersections listed above one can find the slope of a line. To demonstrate solving, we will solve for slope three way using the same method, different points:

___________________________________

Option 1: (-3,5), (0,4)

[With ordered pairs, x is always listed first followed by y]

slope between two points = change in y / change in x

so slope = (5 - 4) / (-3 - 0)

slope = 1/-3

slope = -1/3

___________________________________

Option 2: (0,4), (3,3)

[With ordered pairs, x is always listed first followed by y]

slope between two points = change in y / change in x

so slope = (4 - 3) / (0 - 3)

slope = 1/- 3

slope = -1/3

___________________________________

Option 3: (-3,5), (3,3)

[With ordered pairs, x is always listed first followed by y]slope between two points = change in y / change in x

so slope = (5 - 3) / (-3 - 3)

slope = 2/- 6

reduce to:

slope = 1/- 3

slope = -1/3

___________________________________

NOTES: a tip to check if a slope will be positive or negative can be found by just looking at the graph. If the lower part of the line is to the left, the slope will be positive. If the lower part of the line is to the right (as in question), the slope will be negative.

- The coordinates of C prime are (0.75, 0.5).
- The coordinates of C prime are (1.5, 1).
- The scale factor is One-eighth.
- The scale factor is 8.

Answer:

i think it is C

Step-by-step explanation:

Answer:

When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)

Applying the concept:

Given A(-2, 4) and A'(-0.25, 0.5), which means , and .

Substituting -2 for x in the equation , we get the below equation:

Now we need to find B' and C' by multiplying 0.125 with the x-coordinate and y-coordinate.

-----

x-coordinate of B is -2, y-coordinate of B is 8

x-coordinate of B'

y-coordinate of B'

-----

x-coordinate of C is 6 and y-coordinate of C is 4

x-coordinate of C'

y-coordinate of C'

Conclusion:

The below are the TRUE statements:

(i) The coordinates of C' are (0.75, 0.5)

(ii) The scale factor is 1/8

(iii) The coordinates of B' are (–0.25, 1).

The length of a rectangular fenced enclosure is 12 feet more than the width

If farmer Dan has 100 feet of fencing, find the dimensions of the rectangle with the largest perimeter that can be created using 100 feet of fencing.

Answers

length = 31 ft
width = 19 ft

Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12

The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w

Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.

Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft

Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft

Answer:

length = 31 ft

width = 19 ft
