The endpoints of a line segment graphed on the coordinate system are (−7, 3) and (2, 5). What is the range of the graph? the x values are the domains which are the first numbers so in this case the domains would be -7 and 2 but this question is talking about range which is the y in other words its the second numbers which is 3 and 5
A coordinate plane with 4 lines. The first line is labeled a(x) and passes through (2, negative 4) and (0, 2) and continues past (negative 1, 5). The second line is labeled f(x) and passes through (negative 6, negative 6), (negative 3, 0), and (0, 6). The third line is labeled g(x) and passes through (negative 2, negative 7), (0, negative 3), (1, negative 1) and (2, 1). The fourth line is labeled h(x) and passes through (negative 6, negative 6), (0, negative 3), and (6, 0). When Janelle woke up, it was –3 degrees Fahrenheit outside. As the morning progressed, the temperature rose 2 degrees every hour. Which line on the graph could represent this scenario? a(x) f(x) g(x) h(x)
Answer:

Data Set A has a mean of 215 and a standard deviation of 35. Data Set B has a mean of 400 and a standard deviation of 12.
Which data set is more spread out?
Answer:
Data set A
Step-by-step explanation:
Data set A is the one that is more spread out.
The mean is the same as the average of a given sample. It is usually a measure of the central tendency of a data set.
Standard deviation is a measure of the spread of a given set of data.
The lower the value of the standard deviation, the more clustered around the mean a data is. Data is spread out if it has a higher value of standard deviation.Since data set A has a standard deviation of 35, it the most spread out.
[3b+9]-16=-52
i just want to see if i got the correct answer my answer was
b=-15
Answer:
yes, the answer is b = -15
Step-by-step explanation:
3(-15) = -45
-45 + 9 = -36
-36 - 16 = -52
so b = -15
(X-7)(3x+2) need answer!!
Answer: the answer is
=3[tex]x^{2}[/tex]−19x−14
Step-by-step explanation: (x−7)(3x+2)
=(x+−7)(3x+2)
=(x)(3x)+(x)(2)+(−7)(3x)+(−7)(2)
=3x2+2x−21x−14
=3x2−19x−14
How do I write an equation in point-slope form for m=-3 (-2,-1) ?
Answer:
y + 1 = -3(x + 2)
Step-by-step explanation:
Point-slope form is y - y1 = m(x - x1)
m= -3 (-2, -1)
Plug -3 in for the m in the equation, -2 in for x1, and -1 in for y1
y - (-1) = -3(x - (-2))
Subtracting negatives will make them positive
y + 1 = -3(x + 2)
This is the point-slope form, continuing to solve for y will give the y-intercept form.
Y-intercept Form:
y = -3x - 7

Wilson paints 40% of a bookcase in 20 minutes.
How much more time will it take him to finish the bookcase?
Answer:
30 minutes
Step-by-step explanation:
The percentage rises up by 40% every 20 minutes and if we divide that in half he paints 20% in 10 minutes. Wilson needs to paint 60% more of the bookcase. 40% plus 20% is 60%. So we just add 20 with 10 to get 30 minutes.
work out 7 x 10 to the power of five /2 x 10 to the power of 2
Answer: 3500
Step-by-step explanation:
7 x 10 to the 5th power = 700000
2 x 10 squared = 200
700000/200 = 3500
Answer:
4201750

En la casa de Juan, van a pedir pizza para la comida, pero cuando la van a pedir se dan cuenta que deben pedirla por perímetro o área de la misma. La mamá dice que es más grande la de perímetro de 100cm y el papá dice que es más la de área de 100cm². ¿Cuál tiene la razón? *
Responder:
La pizza con un perímetro de 100 cm es más grande ¿verdad?
Explicación paso a paso:
Deja que la pizza tenga forma circular.
Sea el área de la pizza = πd² / 4 y;
Perímetro de la pizza = πd
d es el diámetro de la pizza
Si la madre dice que el que tiene un perímetro de 100 cm es más grande, para estar seguros necesitamos obtener el diámetro de la pizza. La de mayor diámetro será la pizza más grande.
P = 100cm
100 = πd
d = 100 / π
d = 100 / 3,14
d = 31,85 cm
El diámetro de la pizza mamá es de 31,85 cm.
Si el padre dice que el que tiene un área de 100 cm² es más grande, obtengamos también el diámetro para estar seguros.
A = πd² / 4
100 = πd² / 4
400 = πd²
d² = 400 / π
d² = 400 / 3,14
d² = 127,39
d = √127,39
d = 11,29 cm
Por lo tanto, el diámetro de la pizza padre es de 11,29 cm.
Dado que el diámetro de la pizza madre es mayor que el de esa, la pizza con un perímetro de 100 cm es más grande, lo que demuestra que la madre tiene razón.

Answer:
72 degrees
Step-by-step explanation:
hi! the total angle measure of a triangle is 180 degrees. so, all three angle measures must add up to 180.
6x+6x+8x=180
20x=180
x=9
now, plug in x=9 for angle ABC.
8(9)= 72
m<ABC= 72 degrees
Find the equation of the line shown.
Given : A graph of linear equationis given to us.
To Find : The equation of the line .
Solution : Here we can see that the line passes through points ( 1 , 2 ) and ( 2 , 4). So , clearly here we can use Two - point form to find the equation of the line .
So , first point will be , ( 1 , 2 ) & second point will be ( 2 , 4 ) . So here ;
[tex]\sf x_1 = 1\: \& \:y_1 = 2[/tex][tex]\sf x_2 = 2\: \&\: y_2=4[/tex]Now , the two point form formula is :
[tex]\Large\boxed{\red{\sf \purple{\mapsto} y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)}}[/tex]
[tex]\tt:\implies y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]
[tex]\tt:\implies y-2=\dfrac{4-2}{2-1}(x-1) [/tex]
[tex]\tt:\implies y-2 = \dfrac{2}{1}(x-1) [/tex]
[tex]\tt:\implies y-2=2(x-1)[/tex]
[tex]\tt:\implies y -2 = 2x - 2 [/tex]
[tex]\underline{\boxed{\purple{\tt\longmapsto 2x - y = 0}}}[/tex]
