Standard to Slope Intercept Form
Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x+8y=24
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
2x + 8y = 24 ( subtract 2x from both sides )
8y = - 2x + 24 ( divide all terms by 8 )
y = - [tex]\frac{1}{4}[/tex] x + 3 ← in slope- intercept form

A clap of thunder is recorded at two weather stations that are 2 miles apart. Station A recorded the sound 3 seconds before station B. Since 1 mile is 5,280 feet and assuming sound travels at 1,100 feet per second, which equation can be used to determine the location of the thunder?
Answer:
C.
was right on edge 2021
The correct option is (C)
What is equation?An equation is a mathematical expression that contains an equals symbol.
Given:
Sound travels= 1100 feet per second
Stations are 2 miles apart from each other, i.e., 10560 feet.
Using,
x²/a² + y²/b²=1
So, 2c= 10560
c=5280
and, 2c-2a +3300 = 10560
2a= 3300
a= 1650
So, b²= c² - a²= 25155900
x²/2722500 + y²/25155900=1

Please help ASAP really desperate
Answer:
m= 3/7
Step-by-step explanation:
I'm assuming the question is solve for the variable, m.
First step is to isolate the variable
In other words, let's move everything (but m) from the left side to the right side
To move 7 to the right side, we can either divide both sides by 7 or multiply both sides by 1/7 (both equal the same thing)
7/3m × 1/7 = 1 × 1/7
1/3m = 1/7
Now we must move 1/3 from the left to the right side
We can use the reciprocal, 3/1, to do this
1/3m × 3/1 = 1/7 × 3/1
m = 3/7
Jessica estimated that her family used 30% more water this month compared to last month . they used 12000 gallons of water last month , how much water did they use this month
Answer:
15,600 Gallons
Step-by-step explanation:
The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Last used of water = 12000
30% of 12000 = (30/100)12000 = 3600
Water used in the current year = 12000 + 3600 = 15600 gallons.
Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".

I'm struggling a little bit can someone help?? A cell phone costs $850. You have a coupon for 15% off. How much will you pay for the phone? Include 13% tax
Answer:
722.50
Step-by-step explanation:
not exactly sure its right but i did use a calculator so I'm pretty sure it's right
Given:
850 dollars is the original price of the cell phone. (discount) coupon for 15% offtax is 13 percent.------------------------------------------------------------------
original price - discount = sales price
850 - (850 x [tex]\frac{15}{100}[/tex] ) = sales priceANSWER: $722.50 or [tex]\frac{1445}{2}[/tex]Include 13% tax... price + sales tax = total price of the phone
722.50 + (722.50 x [tex]\frac{13}{100}[/tex] ) = ?ANSWER: The final price of the cellphone is $816.43

Answer:
1/2
Step-by-step explanation:
There are 6 marbles that are either red or green out of 12 total marbles, so you have:
6/12 = 1/2
Answer:
1/2
Step-by-step explanation:
To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:
[tex]\frac{5+1}{12}[/tex] or [tex]\frac{6}{12}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex].

Find the missing value to the nearest hundredth cos=4/38
Answer:
83.96 (approximately)
Step-by-step explanation:
I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.
It should look like:
[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.
Hopefully this is right, if not, please let me know. Good luck.
Find the area of the trapezoid by decomposing it into other shapes
Answer:
60 cm ( squared )
Step-by-step explanation:
you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).

21 children in Year 5 can swim.
There are 30 children in Year 6
18 of these 30 children can swim.
(i) Work out the number of children in Year 4 who can swim.
Answer: 20 children
Step-by-step explanation:
Given
Year 4: 11 cannot swim
Year 5: 21 can swim
Year 6: 18 of 30 can swim
Total 96 children
Total 37 cannot swim
First Step: find the number of people from year 5 who cannot swim
There are 30-18=12 people who cannot swim in year 6There are 11 who cannot swim in year 4Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5Second Step: find the number of children in year 5
There are 21 children who can swimThere are 14 children who cannot swim21+14=35 childrenThird Step: find the number of children in year 4 who can swim
There are 30 children in year 6There are 35 children in year 5There are 11 children in year 4 who cannot swimThere are in total 96 children96-30-35-11=20 children in year 4 who can swimHope this helps!! :)
