To find slope use y2 - y1 / x2 - x1. I would suggest doing this twice just to make sure.
For this one, I will use the first three points. (2,2) (4,5) (6,8)
8 - 5 / 6 - 4 = 3/2
5 - 2 / 4 - 2 = 3/2 = your slope
Now, since there is no (0,y) given, we need to find the y-intercept using . . . You guessed it! Point - slope form! I will use the point (2,2)
y-y₁=m(x-x₁)
y - 2 = 3/2 (x - 2)
y - 2 = 3/2x -3
+2 +2
Y = 3/2x -1
-1 = your y-intercept form.

You got it right. Triangle DAC
Step-by-step explanation:
Line segment DA is a perpendicular bisector(it cuts line segment CE perfectly in half making line segment AE an CA congruent. Since the triangle share line segment DA that makes them congruent by the SAS postulate
The triangle that is similar to triangle EAD using the Peices of right triangle would be; Triangle DAC
Line segment DA is a perpendicular bisector which cuts line segment CE perfectly in half making line segment AE and CA congruent.
Since the triangle share line segment DA that makes them congruent with the SAS postulate.
Therefore, Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
Therefore, the similar triangle is DAC

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
Answers
Perimeter 2(3w-2)+2w
Perimeter 6w-4+2w=8w-4
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.

Approximate √10 to the nearest whole number
Answers
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.

A Line Passes Through The Point (-6, 7) and has a slope of -5/2.
Write An Equation In Slope-Intercept Form For This Line.
Answers
because since y= m(slope)x + b
and we already have the slope, to find b we need to plug in (-6 (for x),- 7 for y)
so -7= -5/2(-6) + b
and then we multiply -5/2 times -6 which equals to 15 so then we do
-7= 15 + b
and then we subtract 15 from -7 (-7 -15)
to give us -22= b
and then we have the full eq of y= -5/2 -22

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?
Answers
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)
8- Quien comió mas galletas fue primo, que comió 35 galletas.
- 3x + y = 3
2y = -3x - 12
Answers
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

A florist uses 225 branches of winterberry to make 75 wreaths. Based on the ratio or unit rate, how many branches of winterberry will the florist use for 25 wreaths?
Answers
Answer:
the number of branches required to use 25 wreaths is 75 branches
Step-by-step explanation:
Given that
The florist used 225 branches of winterberry for making 75 wreaths
First we have to compute the unit rate or the ratio
= 225 ÷ 75
= 3 : 1
Now the number of branches required to use 25 wreaths is
= 3 × 25
= 75 branches
Hence, the number of branches required to use 25 wreaths is 75 branches

(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:
Answers
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)

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.
Answers
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.❌
