3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
Answer:
y = 1/2x - 1/3
Step-by-step explanation:
subtract 3x from each side first to get:
-6y = -3x - 2
divide each side by -6 to get:
y = 3/6x - 2/6
simplify:
y = 1/2x + 1/3

Light travels at approximately 186,000 miles per second. How is 186,000 written in scientific notation?
Answer:1.86*10^5
Step-by-step explanation:
Scientific notation is simple. First you place a decimal after the first numerical digit. Then for every digit after the decimal you would multiply by 10 to get back to the standard form. Instead of constantly multiplying by 10 you will raise the exponent.

Three consecutive integers add up to 51. What are these integers
Let the three consecutive integers be x, x+1 and x+2.
According to the question, x+x+1+x+2=51
=>3x+3=51
=>3x+3-3=51-3
=>3x=48
=>x=16
Hence, first integer = 16,
second integer = 16 + 1 = 17 and
third integer = 16 + 2 = 18.
Selecting two marbles from a bag containing the numbers 2,4,6,8,10,12 (with replacement) what is the probability of selecting two numbers less than 10 ?
Given:
A bag containing the numbers 2,4,6,8,10,12.
To find:
The probability of selecting two numbers less than 10.
Solution:
We have,
Total numbers = 6
Numbers less than 10 are 2,4,6,8.
Numbers less than 10 = 4
Probability of getting a number less than 10 is:
[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]
[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]
[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]
We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.
Probability of selecting two numbers less than 10 is:
[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]
[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]
[tex]\text{Required probability}=\dfrac{4}{9}[/tex]
Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].

Answer:
First, we can find the least common denominator for 8 and 3 which is 24.
5/8 = 15/24
1/3 = 8/24
Then we can divide 15/24 by 8/24 which is 2 1/4.
If we then do 16 divided by 2 1/4 we get 7 1/9
Answer = 7 1/9

Hope this helps!-FinnyA = {prime numbers between 4 and 25} B = {odd numbers less than 16} List the outcomes of A, B and explain? List the outcomes of A, B and explain?
The image below better explains it. Thank you.
Answer:
A u B = {1,3,5,7,9,11,13,15,17,19,23}
A n B = {5,7,11,13}
Step-by-step explanation:
The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23
A = {5, 7,11, 13, 17, 19,23}
B are odd numbers less than 16
B = {1, 3 , 5,7,9,11,13,15}
The union of both is the list of all values present in both sets without repeating;
A u B = {1, 3, 5,7,9,11,13,15,17,19,23}
A n B is the set that contains values that are present in both sets
A n B = {5,7,11 , 13}
A class has 12 boys and 16 girls. The teacher needs to pick two volunteers. What is the probability that she chooses a girl given that she chose a boy first? All answers should be given as a fraction in simplest form!
Any help is appreciated!
Answer:
16/27
Step-by-step explanation:
12 boys and 16 girls
She already chose a boy so now there are (11+16) = 27 possible outcomes
There are 16 favorable outcomes(girl)
so the fraction is 16/27

Answer:
cos A = 24/51
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Cos theta = adj side/ hypotenuse
cos A = 24/51
Step-by-step explanation:
We know that cosA=Base/hypontenuse
➡CosA=24/51
Reason :-This is a right angle triangle
Cos theta=Base/hypontenuse

m3 should be 70°
all internal angles of a triangle add up to 180
180-35-75 = 70
Answer:
All angles of a triangle add up to 180°.
there m1+m2+m3=180°
35+75+m3=180
110°+m3=180°
m3=180°-110°
m3=70°

The football team has a total of 50 jerseys. There are 20 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys?
Answer:40%
Step-by-step explanation:20 divided by 50 is 0.4 then multiply that by 100 and get 40
Answer:
Well the equation for this would 50*.20 = ...
The first half of the answer would be 10.
BUT!
You need to subtract 10 from 50.
50-10 = 40!
There you go.

Which function shown below has the greater rate of change? Explain. (Be sure to include the
rate of change for each in your explanation).
Answer:
Function 1 has a greater rate of change.
Step-by-step explanation:
Function 1 has a rate of change of 3 because 3x is the slope of the line.
Function 2 has a rate of change of 1.5, because when you use rise/run, you get a slope of 3/2.
Function 3 has a rate of change of 2. You use the formula (y2 - y1) / (x2 - x1) to find the slope. I used (0,0) and (1,2). When you plug in 2 for y2, 1 for x2, and 0 for y1 and 0 for x1, you get (2-0) / (1-0) which is 2/1. That equals a slope of 2.

What is the surface area of a cereal box with a height of 10 inches, a width of 4 ½ inches, and a length of 7 inches?
Answer:
Surface area of a box = 293 inches ²
Step-by-step explanation:
Surface area of a box = 2(lw + lh + hw)
Where,
l = length = 7 inches
w =width = 4 1/2 inches
h = height = 10 inches
Surface area of a box = 2(lw + lh + hw)
= 2(7*4.5 + 7*10 + 10*4.5)
= 2(31.5 + 70 + 45)
= 2(146.5)
= 293 inches ²
Surface area of a box = 293 inches ²
solve the following :
7+2x/3= 5
and
3x+4/2= 9.5
Answer:
x= 4
x= 5
Step-by-step explanation:

7 + 2(4)/3 = 5
7+8/3 = 5
15/3 = 5
3(5) +4/ 2 = 9.5
15+4/2 = 9.5
19/2 = 9.5

The measure of angle P is ___ degrees, rounded to the nearest hundredth.
Answer:
53°
Step-by-step explanation:
Use sine cosine or tangent (SOHCAHTOA). For this example I'll use sine.
For sine you'd use the equation sin(x)=[tex]\frac{opp}{hyp}[/tex] where x is the missing angle measure
the opposite side from x is 45 cm and the hypotenuse is 53 cm
sin(x)=[tex]\frac{45}{53}[/tex]
then rearrange the equation like this x=[tex]sin^{-1}[/tex]([tex]\frac{45}{53}[/tex])
most graphing calculators should solve it from there if you plug it in, hope this helps! :)

write the slope-intercept form of the equation of the line through the given points.
Answer:
y = 4x - 7 (Answer C)
Step-by-step explanation:
First find the slope of this line. Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.
Thus, the slope, m, is
m = rise / run = 4/1, or m = 4.
Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:
y - k = m(x - h) becomes y - 1 = 4(x - 2)
Solving for y, we get: y = 4x - 8 + 1, or y = 4x - 7 (Answer C)
