If the width of the dining room table is w feet, and the length is 3w - 2 feet, write an algebraic expression that represents the perimeter of the table
The required algebraic expression that represents the perimeter of the dining room table is 8w - 4.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
Here,
The perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Substituting the given expressions for the length and width of the dining room table, we get:
P = 2(3w - 2) + 2w
Simplifying the expression, we get:
P = 6w - 4 + 2w
Combining like terms, we get:
P = 8w - 4
Therefore, the algebraic expression that represents the perimeter of the dining room table is 8w - 4.

Two sidewalks in a park are represented by lines on a coordinate grid. Two points on each of the lines are shown in the tables. Sidewalk 1 x y 2 5 0 1 Sidewalk 2 x y 1 3 3 -3 (a) Write the equation for Sidewalk 1 in slope-intercept form. (b) Write the equation for Sidewalk 2 in point-slope form and then convert to slope-intercept form. (c) Is the system of equations consistent independent, coincident, or inconsistent? Explain. a. Note: Review 2.11 Strange Solutions and 5.04 Classifying Systems if you’re not sure where to start. (d) Use the substitution or elimination method to solve your system, and explain which one you picked. If the two sidewalks intersect, what are the coordinates of the point of intersection? Answer:
Answer:
y = 2x + 1 ;
y - 3 = - 3(x - 1) ; y = - 3x + 6 ;
Independent ;
(1, 3)
Step-by-step explanation:
Given the data:
Sidewalk 1:
x __ y
2 _ 5
0 _ 1
Sidewalk 2:
x __ y
1 _ 3
3 _ -3
Equation for sidewalk 1 in slope - intercept form:
Slope intercept form:
y = mx + c
c = intercept ; m = slope
m = (change in y / change in x)
m = (1 - 5) / (0 - 2) = - 4 / - 2 = 2
Y intercept ; value of y when x = 0
(0, 1) ; y = 1
Hence, c = 1
y = 2x + 1
Sidewalk 2:
Point slope form:
y - y1 = m(x - x1)
m = slope
m = = (-3 - 3) / (3 - 1) = - 6/2 = - 3
Point (x1, y1) = (1, 3)
y - 3 = - 3(x - 1)
To slope intercept form:
y - 3 = - 3(x - 1)
y - 3 = - 3x + 3
y = - 3x + 3 + 3
y = - 3x + 6
Since the slope of both lines are different, intersection will be at single point and will have a single solution. This makes it independent.
Using substitution method :
y = 2x + 1 - - - (1)
y = - 3x + 6 - - - (2)
Substitute (1) into (2)
2x + 1 = - 3x + 6
2x + 3x = 6 - 1
5x = 5
x = 1
From (1)
y = 2(1) + 1
y = 2 + 1
y = 3
Coordinate of the point of intersection = (1, 3)

1.Tu familia compro un paquete de galletas, al abrirlas se comieron la mitad de ellas, entre tu papá, mamá, hermano mayor, hermana menor y tú, comiendo la misma cantidad de galletas; después llego tu tía y primo y ellos se comieron la mitad de lo que quedaba, donde tu primo se comió 10 galletas más que tu tía; luego llego tu tío y se comió la mitad del resto y finalmente, tú tomas de galletas de lo que queda, sobrando 30 galletas.
1. Cuantas galletas había en el paquete
Cuántas galletas se comió tu
1. mamá
2. papá
3. hermano mayor
4. hermano menor
5. tía
6. primo
7. ¿Cuántas galletas comiste tú?
8. Quién comió más galletas?
Answer:
Para determinar cuantas galletas comió cada integrante de la familia, se debe realizar la siguiente ecuación:
P + M + HMA + HME + YO = 1/2 X
(PR+10) + TIA = 1/4 X
TIO = 1/8 X
Sobran 30 galletas, es decir, 1/8 X
Punto 1)
Si 1/8 X es igual a 30, en el paquete había 240 galletas (30 x 8).
Punto 2)
1- Mamá comió 24 galletas (30 x 4 / 5)
2- Papá comió 24 galletas (30 x 4 / 5)
3- Hermano mayor comió 24 galletas (30 x 4 / 5)
4- Hermano menor comió 24 galletas (30 x 4 / 5)
5- Tía comió 25 galletas ((30 x 2 - 10) / 2)
6- Primo comió 35 galletas ((30 x 2 + 10) / 2)
7- Yo comí 24 galletas (30 x 5 / 5)

For two weeks, the highest temperature each day was recorded in four different cities. Lines 1, m, ,
and pare graphs of the temperatures over time in Louisburg, Memphis, New Orleans, and Phoenix.
Which statement is true?
A The initial high temperature in Louisburg is lower than it is in Memphis.
B Memphis is the only city whose highest temperature decreases.
C Louisburg always has the highest temperature.
D The high temperature in Phoenix rose faster than the high temperature in New
Orleans.
Answer:
B. Memphis is the only city whose highest temperature decreases.
Step-by-step explanation:
Let's analyse each statement looking at the graph given to see how true it is or not:
A. "The initial high temperature in Louisburg is lower than it is in Memphis."
Initial temperature is the y-intercept, that is, it is the point at which the line intercepts the y-axis.
Therefore, the city that has the greatest initial high temperature is Louisburg, which has a blue line labelled l. As you can see, the y-intercept has greater than every other city.
Therefore, Statement A is NOT TRUE.❌
B. "Memphis is the only city whose highest temperature decreases."
The line of Memphis slopes downwards from the left to our right. This shows a decrease in the highest temperature of Memphis. The line of every other city is either horizontal or slopes upwards.
Therefore, Statement B is TRUE.✅
C. "Louisburg always has the highest temperature."
The line of the graph of New Orleans shows that it's highest temperature exceeds that of others. As you can see, the line surpasses that of the rest three. So, Louisburg does not always have the highest temperature.
Therefore, Statement C is NOT TRUE.❌
D. "The high temperature in Phoenix rose faster than the high temperature in New
Orleans."
The slope of the line of New Orleans is more steeper than that of Phoenix. So, New Orleans high temperature rise faster compared to that if Phoenix.
Therefore, statement D is NOT CORRECT.❌

- 3x + y = 3
2y = -3x - 12
Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6

Approximate √10 to the nearest whole number
Answer:
3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Since square rooting (√) is the opposite function of squaring a number (exponent of 2), to approximate √10 to the nearest whole number, determine the two squares it is in between.
If you square 3, you will get 9 (3 x 3 = 9) and if you square 4, you will get 16 (4 x 4 = 16). Since 10 is in between 9 and 16, √10 will be in between 3 and 4.
The difference between 9 and 10 is only 1, while the difference between 10 and 16 is 6. Therefore, √10 is closest to 3.

RDN’s sales of cable modem in San Mateo, California, for the months of January through April were as follows:January February March April 50 80 70 60Suppose exponential smoothing is used with a smoothing constant (alpha) of 0.30. If the forecast for January were 50, the forecast for May would be approximately:a. 51.60b. 59.04c. 60d. 53.08e. 50
To calculate the exponential smoothing forecast for May, we need to use the formula Therefore the correct option is A 51.60 .
[tex]Ft = alpha * Xt + (1 - alpha) * Ft-1[/tex] Where: - Ft is the forecast for time period t - Xt is the actual sales for time period t - Ft-1 is the forecast for the previous time period (t-1) - alpha is the smoothing constant Given that the forecast for January is 50, we can calculate the forecast for February as follows: [tex]F1 = 0.30 * 50 + (1 - 0.30) * 50 = 50[/tex] Similarly, we can calculate
the forecasts for March and April: F2 [tex]= 0.30 * 80 + (1 - 0.30) * 50 = 65[/tex] F3 [tex]= 0.30 * 70 + (1 - 0.30) * 65 = 66.50[/tex] F4 [tex]= 0.30 * 60 + (1 - 0.30) * 66.50 = 63.05[/tex] Now, to calculate the forecast for May: F5 [tex]= 0.30 * Xt-1 + (1 - 0.30) * Ft-1 F5 = 0.30 * 60 + (1 - 0.30) * 63.05 F5 ≈ 51.60[/tex] Therefore, the forecast for May using exponential smoothing with a smoothing constant of 0.30 is approximately 51.60 (option a).
