Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] ) point - slope form of a line.
y = mx + b slope- intercept form of a line.
~~~~~~~~~~~~~~~~~
( - 2, - 7 )
( 0, - 4 )
m = [tex]\frac{- 4 - (-7)}{0 - (- 2)}[/tex] = [tex]\frac{3}{2}[/tex]
y - ( - 4 ) = [tex]\frac{3}{2}[/tex] ( x - 0 )
y + 4 = [tex]\frac{3}{2}[/tex] x
y = [tex]\frac{3}{2}[/tex] x - 4 slope- intercept form

Answer:
17 + 6h = 71
Step-by-step explanation:
17 dollars for a bike + 6 times the amount of hours will equal the total that he gave.
to manipulate this equation to find h, isolate it first.
6h = 71 - 17
6h = 54
h = 54/6
h = 9
Which of the following expressions represents the value, in dollars, of a certain number of dimes, d, and pennies, p?
Answer:
If your answer choices are:
0.01d + 0.10p
0.10d + 0.01p
0.11dp
0.11d + p
A dime is 10% of a dollar and a penny is 1% of a dollar, or 0.10 and 0.01
Then 0.10d + 0.01p is the expression

2. Pat also made a container of punch. She gave 1/12 of the punch to her mother to try and ⅛ of the punch to each of her two sisters. What fraction of the punch was left to take to the party? (*Hint 12/12 - 1/12 - 1/8 - 1/8 = ?)
lol, pls help as soon as you can!
Answer:
2/3
Step-by-step explanation:
1 - (1/12 + 2·1/8)
= 12/12 - (1/12 + 1/4)
= 12/12 - (1/12 + 3/12)
= 12/12 - 4/12

A bus travels from town A to town B. If the bus's speed is 50 km/hr, it will arrive in town B 42 min later than scheduled. If the bus increases its speed by \displaystyle \frac{50}{9}
9
50
m/sec, it will arrive in town B 30 min earlier than scheduled. Find:
A) The distance between the two towns;
B) The bus's scheduled time of arrival in B;
C) The speed of the bus when it's on schedule.
Answer:
60 km/hr
Step-by-step explanation:
First we will determine the speed of the bus following it's increase. The speed is increased by:
50m/9sec=50.60.60/9/1000 .km/hr=20 km/hr
Therefore, the new speed is V = 50 + 20 + = 70
km/hr. If x is the number of hours according to the schedule, then at the speed of 50 km/hr the bus travels from A to B within ( x + 42/60 ) hr. When the speed of the bus is V = 70 km/hr, the travel time is x -30/60 hr. Then:
50(x+42/60)=70(x-30/60)
5(x+7/10)=7(x-1/2)
7/2+7/2=7x-5x
2x = 7
x=7/2 hr
So, the bus is scheduled to make the trip in 3 he 30 minutes.
The distance between the two towns is 70 ( 7/2 – 1/2 ) = 70 • 3 = 210 km and the scheduled speed is:
270/7/2=60km/hr

Find the volume of the sphere.
Either enter an exact answer in terms of 7 or use 3.14 for I and round your final answer to the nearest hundredth.
units
Answer:
Volume of the given sphere = 4.19 units³
Step-by-step explanation:
Volume of a sphere is given by the expression,
V = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here, r = radius of the sphere
From the picture attached,
Radius of the sphere 'r' = 1 unit
Volume of the given sphere = [tex]\frac{4}{3}\pi (1)^3[/tex]
= [tex]\frac{4}{3}\pi[/tex]
= [tex]\frac{4}{3}(3.14)[/tex]
= 4.187
≈ 4.19 units³

Divide 840 in the ratio 3: 4: 5
Answer:
210 280 350
Step-by-step explanation:
add the sum of the ratio
divide the actual number by the sum I. e 840÷12=70
multiply 70 with 3 4 and 5
840 in the ratio 3:4:5 is 36, 48 , 60
What is a ratio?The quantitative relation between two amounts showing the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"
Given here the number 840 and to divide it in the ratio 3:4:5 Let the numbers are 3x ,4x and 5x
thus 3x+4x+5x= 840
x=12
Hence the respective numbers are 36, 48 , 60

m∠c =?? degrees
° m∠d =?? degrees
Answer:
Step-by-step explanation:
This figure better be a square, otherwise there is no answer.
The diagonals of a square intersect at right angles, so d = 90 degrees. That property comes from the rhombus.
Squares have equal sides and the opposite sides are parallel. The triangle containing c is isosceles. The lower right corner is a right angle. So c must equal 45 degrees since the angle on the lower left must equal 45 degrees as well
Answer
c = 45
d = 90

1?
Your answer
Answer:
15°
Step-by-step explanation:
Reference angle = [tex] \theta [/tex]
Side Opposite to reference angle = 10
Hypotenuse = 39
Let's use arcsin:
recall: SOHCAHTOA
Therefore:
[tex] \theta = sin^{-1}(\frac{Opp}{Hyp}) [/tex]
Substitute
[tex] \theta = sin^{-1}(\frac{10}{39}) [/tex]
[tex] \theta [/tex] = 14.8571655° = 15° (to nearest whole number)

Calcular "E" y dar como respuesta la suma de sus cifras. A) 900 B) 1200 c) 1800 D) 2700 E) 9990
Answer:
0.1. B) 50%
0.2 A) Psicología
Step-by-step explanation:
01. Dejemos que 'x' e 'y' representen el porcentaje de boquichicos y carachamas en la piscifactoría, tenemos;
Dado que el 30% de los boquichicos es el 20% del número de carachamas
30% x = 20% y
∴ 0.3 · x = 0.2 · y
Por lo tanto, tenemos;
x / y = 0,2 / 0,3 = 2/3
Por lo tanto, por cada 100% de pescado, tenemos;
x + y = 100%
x = 2/3 · y
2/3 · y + y = 100%
5 · años / 3 = 100
y = 100 × 3/5 = 60%
El porcentaje de carachamas en la finca, y = 60%
∴ x = 100% - y = 100% - 60% = 40%
El porcentaje de boquichicos en la finca, x = 40%
Por lo tanto, tenemos el 80% del pescado en la granja, obtenemos;
Si hay 100 peces en la granja, 80% = 80 peces
Pero el número de los 100 peces que son boquichicos en la granja = 40% × 100 = 40 peces
Por lo tanto, los boquichicos son la mitad del 80% del número de peces o el 50% de los peces en la piscifactoría.
La opción correcta es;
B) 50%
02. Tenemos;
El costo de un libro de psicología> El costo de un libro en inglés
El costo de un libro de matemáticas> El costo de un libro de historia
El costo de un libro de psicología> El costo de un libro de matemáticas
Por lo tanto, tenemos;
El costo de un libro de psicología> El costo de un libro de matemáticas> El costo de un libro de historia
∴ El libro de Psicología es más caro que todos los demás libros y, por tanto, es el libro más caro

Answer:
The multiplicity of the root is 1
Step-by-step explanation:
Firstly, we need to understand what multiplicity is
By multiplicity, we simply refer to the number of times we have the certain root repeating itself
From the factorization, each of the given roots were only repeated once
