Answer:
The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.
Step-by-step explanation:
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.
Answer:
The remaining materials from the sun's formation clumped together due to gravity.

how are rates and unit rates different?
Answer:
down bellow
Step-by-step explanation:
A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

Solve 3[–x + (2 x + 1)] = x – 1.
Answer:
x = -2
Step-by-step explanation:
3{-x + 2x + 1} = x - 1
-3x + 6x + 3 = x - 1
3x + 3 = x - 1
2x = -4
x = -2

Answer:
C
Step-by-step explanation:
Let the age of the older girl be y and the age of the younger girl be x.
The sum of their ages is 27.
x + y = 27
The older girl is 6 years older than twice the age of the younger girl.
twice the age of younger girl = 2x
y = 6 + 2x

4. Identify the domain and range of the
function in Item 4, including their units.
domain:
range:
Answer:
See below
Step-by-step explanation:
1. The rule defining the function on the graph:
y = x -1, if x = (-3,-1)y = -3x + 9, if x = [2, 4)2. f(x) = |4x + 36|
y = 4x + 36, if x ≥ - 9y = -4x - 36, if x < - 93. See attachment for the graph
4. Item 4 is not included in the question

10x - 1
Step-by-step explanation:
30x^2 − 33x + 3 =
= 3(10x^2 - 11x + 1)

Answer: 10x - 1
Sam wants to write an equation to represent a
proportional relationship with a constant of proportionali
of 6. He writes the equation y = 6 + X.
Is he correct. If not, what is the correct equation? Explai
your answer. Consider the graph of the equation in your
response
Answer:
No, Sam is not correct. The graph of a proportional relationship has the form y = kx, where k is the constant of proportionality. Sam added the constant of proportionality instead of using it as the coefficient of x. The correct equation is y = 6x. Sam’s graph would be a straight line, but it would not pass through the origin.

Write the equation of a line in slope intercept form that passes through (2,4) and (-7,8)
Answer:
y = -4/9x + 44/9
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
m = ( 8-4)/( -7-2)
= 4/-9
= -4/9
The slope intercept form is
y = mx+b
y = -4/9 x+b
Substitute a point into the equation
4 = -4/9 * 2 +b
4 = -8/9+b
36/9 = -8/9 +b
Add 8/9 to each side
36/9 + 8/9 = -8/9 + 8/9 +b
44/9 = b
y = -4/9x + 44/9
Rearange the equation so n is the independent variable m+1=-2n+6 ? M= what
Answer:
m = - 2n + 5
Step-by-step explanation:
Given the equation:
m+1=-2n+6
Rearrange the equation so that n is the independent variable
The independent variable is the predictor variable, Hence causes a change in the value of predicted variable obtained.
m+1=-2n+6
m = - 2n + 6 - 1
m = - 2n + 5
m = - 2n + 5
The general form of a regression equation:
y = ax + b
Where y = dependent variable
x = independent variable ; a = Coefficient of slope ; b = intercept
Hence, the equation : m = - 2n + 5
True or False: All lines are functions. If false give an example of a line that is not a function.
Answer:
False, all lines are not functions.
Step-by-step explanation:
Vertical lines are not functions since they do not pass the vertical line test. In this case, one x-coordinate relates to several y-coordinates.

Answer: Graph (0,10) and (3,9).
Step-by-step explanation: The equation is written in slope-intercept form (y=mx+b). b represents the y-intercept.
So you would graph (0,10) on the graph.
To find the other points, you can use the triangle method for finding slope. -1/3x is the slope. -1 means you go down by one space on the y line. 3 means you go right by 3 spaces on the x line. This leads you to the point (3,9). You can use this method to find the other points on the graph.

Ralph chase plans to sell a piece of property for $145000. He wants the money to be paid off in two ways a short term note at 11% interest and a long term note at 8% interest. Find the amount of each note if the total annual interest paid is $13850.
Given :
Price of property , P = $145000 .
Money paid off in two ways a short term note at 11% interest and a long term note at 8% interest.
Total interest , I = $13850 .
To Find :
The amount of each note .
Solution :
Let , x money is paid off in 11 % interest rate and ( 145000-x) in 8% interest rate.
Therefore , their sum of interest in mathematics is given by :
[tex]\dfrac{11x}{100}+\dfrac{8(145000-x)}{100}=13850\\\\11x+1160000-8x=1385000\\\\3x=225000\\\\x=\$75000[/tex]
Therefore , the amount of note is $75000 and $70000 for 11% and 8% interest rate respectively .
Hence , this is the required solution .

eight feet more than the width.
The perimeter is 60 feet. Find the
length and width.
Answer:
11 and 19
Step-by-step explanation:
solution
let,the lenght be (x+8) and width be x.
Now,
The perimeter of rectangle=2(l*w)
or,60=2(x+8*x)
or,60=4x+16
or,60-16=4x
or,44=4x
or,44÷4=x
x=11
breath=11
length=(x+8)
=11+8
=19

Express the set using the roster method.
{x | XEN and 15 sxs 50}
Choose the correct answer below.
A. {15, 16, 17, 18, ..., 50}
B {16, 17, 18, 19, ..., 50)
C. Ø
D. {..., 12, 13, 14, 51, 52, 53, ...}
I think you meant to write [tex]\{x | x \in \mathbb{N} \text{ and } 15 \le x \le 50\}[/tex]
If so, then the answer is Choice A. {15, 16, 17, 18, ..., 50}
We simply list every natural number from 15 to 50, including both endpoints. The three dots mean "continue this pattern". This way we don't literally have to write out every single value (there are 50-15+1 = 36 values in this set).
Note: the set of natural numbers is {1,2,3,...} so a natural number is basically a whole number, but 0 is not included. Negative values aren't included either.
Find the value of tan A
Answer:
Yellow: [tex]\frac{8}{15}[/tex]
Step-by-step explanation:
tangent = opposite [tex]\div[/tex] adjacent
Opposite A = 16
Adjacent A = 30 (Not 34, since that is the hypotenuse or the longest line in the triangle)
Thus, tan A = [tex]\frac{16}{30} =\frac{8}{15}[/tex]
Answer:
8/15
Step-by-step explanation:
Since this is a right triangle
tan theta = opp/ adj
tan A = 16/ 30
tan A = 8/15

Solve 7x - 8(2x - 3) + 2 = 8 *
Answer:
Step-by-step explanation:
7x - 8(2x - 3) + 2 = 8
Expand bracket and Minus 2 on both sides
7x - 16x + 24 = 6
Minus 24 on both sides, and simplify the "x's"
-9x = -18
Divide by -9 on both sides
x = 2
