Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define equation
y - 3x = -1
Step 2: Find Slope-Intercept Form
Add 3x to both sides: y = 3x - 1And we have our final answer!

The coordinates of the 3 of the vértices of a parallelogram are (-7, 3), (-6, 1), and (-4, 5). What is the equation for the line containing the side opposite the side containing the first two vertices?
We know, opposite sides are parallelogram is parallel, therefore slopes are equal.
Slope of line one :
[tex]m=\dfrac{-7-(-6)}{3-1}\\\\m =\dfrac{-1}{2}\\\\m= -0.5[/tex]
So, equation of other line passing through (-4,5) and have slope of -0.5 is :
y-5 = -0.5( x-(-4))
y-5 = -0.5x - 2
y + 1/2x = 3
2y + x = 6
Therefore, equation of line containing the (-4, 5) is 2y + x = 6.
Hence, this is the required solution.
Relaciona correctamente cada número con sus respectivos múltiplos: 1) 14135 2) 11234125723 A) múltiplo de 3 B) múltiplo de 5 C) múltiplo de 11
Answer:
1) 14135 = B) múltiplo de 5 C) múltiplo de 11
Step-by-step explanation:
Para saber si un numero es un multiplo de otro simplemente tenes que dividir el otro numero por el primero y si el resultado es un numero entero (sin resto y que no es un decimal) entonces es un multiplo de ese numero. En esta pregunta el primer numero (14135) es multiplo de 5 y de 11 por que al dividir no quedan restos, pero no es multiplo de 3 por que si quedan restos.
14135 / 3 = 4,711.666
14135 / 5 = 2,827
14135 / 11 = 1,285
El segundo numero (11234125723) no es multiplo de ninguna de las opciones por que todos dejan restos.
11,234,125,723 / 3 = 3,744,708,574.33333
11,234,125,723 / 5 = 2,246,825,144.6
11,234,125,723 / 11 = 1,021,284,156.636363
Find the value of x and the measure of each angle:
1. x =
2. m∠5x + 62 =
3. m∠3x + 47 =
Answer:
Step-by-step explanation:
Find the supplement of 5x + 62
Call the supplement = z
5x + 62 + z = 180 Subtract 5x + 62 from both sides
z = 180 - (5x + 62) Remove the brackets
z = 180 - 5x - 62
z = 118 - 5x
Add the 3 angles to 180
37 + 3x + 47 + 118-5x = 180 All triangles have 180 degrees. Combine like terms
202 - 2x = 180 Subtract 202 from both sides
-2x = - 22 Divide by -2
x = -22/-2
x = 11
======================
x = 11
5x + 62 = 5*11 + 62 = 55 + 62 = 117
3x + 47 = 3*11 + 47 = 33 + 47 = 80
Note these do not add up to 180. That's because 5x + 63 is outside the triangle.
The supplement of 117 = 63
37 + 63 + 80 = 180 as it should.

A rectangle has a length of (x + 3) centimeters and a width of (½ x) centimeters. If the perimeter is 16 centimeters, what is the length of the rectangle. Write and solve an equation whose solution will give the length of the rectangle.
Answer:
length6.3cmwidth=1.66cmStep-by-step explanation:
Step one:
given data
length =(x + 3)cm
width= (½ x)cm
perimeter= 16cm
Step two:
we know that the perimeter of a rectangular shape is expressed as
P=2L+2W
substitute we have
16=2(x+3)+2 (½ x)
solve for x
16=2x+6+x
16-6=3x
10=3x
divide both sides by 3
x=10/3
x=3.3
we know that length =(x + 3)cm
length =(3.3 + 3)= 6.3cm
width= (½ x)cm
width= (½*3.3)= 1.66cm
It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes At this rate, how many pounds of mashed potatoes can the make with 15 pounds of potatoes?
Answer:
22.5 pounds of mashed potatoes
Step-by-step explanation:
I start by dividing 15 by 10 to see how many pounds of mashed potatoes come from a single potato and get 1.5. I then multiply 1.5 times 15 (our number of potatoes) which gives me the answer of 22.5.
The height of a tree, h, depends on its age, a. The ______________________________ is a function of ____________________. The function notation is __ ( __ ).
Answer:
a. The height is a function of age is denoted as
=> f(age) = age * constant
Step-by-step explanation:
The function f: Age ⇒ Height, where age is from the set Age and height is from the set Height.
The age is the independent variable whose value determines the value of the dependent variable height and the constant is a part of the equation and a number that does not change.
height = age * constant
f(age) = age * constant = height
Eg: if height = age * 3 , where f(5), the height or the f(age) of the height is;
f(5) = 5 * 3 = 15,
The height is 15.

Deandra spent $14.00 of the $20.00 in her wallet. What decimal is equivalent to the fraction of the $20.00 Deandra spent? $14.00 of the $20.00 means 14 over 20.
Answer:
0.7
Step-by-step explanation:
Deandra spent $14.00 of the $20.00 in her wallet.
We write this expression above in a fraction format
= $14.00/$20.00
= 14/20
The decimal is equivalent to the fraction of the $20.00 Deandra spent is:
= 14/20
Dividing both the numerator and denominator by 2
= 7/10
= 0.7

What is the width of a rectangle with length 25" in area 375" squared?
Answer:
Width, W = 15 inches
Step-by-step explanation:
Let L = length of the rectangle
Let W = width of the rectangle
Given the following data;
Area, A of rectangle = 375 in²
Length, L of rectangle = 25 in
*To find the width of the rectangle*
We know that the area of a rectangle is given by the formula;
[tex] Area = length * width [/tex]
[tex] A = L * W[/tex]
Making "W" the subject of formula;
[tex] W = \frac {A}{L} [/tex]
Substituting into the equation, we have;
[tex] W = \frac {375}{25} [/tex]
W = 15 in
Therefore, the width of the rectangle is 15 inches.
It takes a baseball about 5 seconds to come down from up in the air after a player hits a homeroom. Suppose that the ball drops down at a rate of 6 feet per second during time. What integer represents the distance traveled by the ball during this time?
Answer:
[tex]Distance = 30\ ft[/tex]
Step-by-step explanation:
Given
[tex]Time = 5\ secs[/tex]
[tex]Speed = 6ft/sec[/tex]
Required
Determine the distance traveled
Distance is calculated from speed formula as thus:
[tex]Speed = \frac{Distance}{Time}[/tex]
Substitute values for Speed and Time
[tex]6 = \frac{Distance}{5}[/tex]
Make Distance the subject
[tex]Distance = 5 * 6[/tex]
[tex]Distance = 30\ ft[/tex]
Hence, the distance traveled is 30ft

A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters. Given the volume formula for a sphere, 4 3 3 V r , find the volume of water the reservoir can hold. Show your substitution. Express your answer in scientific notation with two decimal places of accuracy.
Answer:
[tex]V=5.23\times 10^8\ m^3[/tex]
Step-by-step explanation:
A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters.
The volume of a hemisphere is given by :
[tex]V=\dfrac{2}{3}\pi r^3[/tex]
Substitute r = 630 m in the above formula
[tex]V=\dfrac{2}{3}\pi \times (630)^3\\\\=5.23\times 10^8\ m^3[/tex]
So, the water reservoir can hold [tex]5.23\times 10^8\ m^3[/tex] of water.
