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
What property is this ?
a(b + c) = ab + ac
Answer:
distributive I'm pretty sure!
Step-by-step explanation:
i hope this helps have a great day:)
Mary drew 79 diagonals in a convex polygon. What is the fewest number of sides her polygon might have had?
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

A city receives 4 inches of snowfall every 6 hours. Write and graph a function that describes the relationship. How long does it take to receive 1
foot of snow? I just need the y= blank part I’m really in need of this for a project thanks
Answer:
y= 2/3x
Step-by-step explanation:
Hi, the slope-intercept would be y= 2/3x. This is because the city receives 4 inches of snow every 6 hours. 4/6 simplified is 2/3.
rewrite 3^-4 without negative exponents
Answer:
[tex]\frac{1}{3^{4} }[/tex]
Step-by-step explanation:
You can rewrite 3⁻⁴ as 1/(3⁴) or 1/81 without negative exponents.
What are the laws of the exponents?The product rule is an exponent rule that states that when you multiply similar bases, the add exponents.
For example, (a²)·(a³) = a²⁺³ = a⁵
You can rewrite 3⁻⁴ as 1/(3⁴) because any number raised to a negative exponent is equal to 1 divided by that number raised to the opposite positive exponent.
So 3⁻⁴ = 1/(3⁴) = 1/81
Another way, you can think of it as "flipping" the base, i.e. (1/3)⁴ = 1/81

There are a total of 96 children in Years 4, 5 and 6
37 of these children cannot swim.
11 children in Year 4 cannot swim.
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!! :)

Solve for c:
c + (-20) = -12
Answer:
8
Step-by-step explanation:
Isolate and solve for C
[tex]c + (-20) = -12\\c - 20 = -12\\c = -12+20\\c = 8[/tex]
Answer:
C = 8
Step-by-step explanation:
By reversing the equation, you can get the result.
-12 + 20 = ?
-12 + 20 = 8
Proofcheck:
8 + (-20) = ?
8 + (-20) = -12

Find the volume of a rectangular pyramid, with a height of 12 cm, length of 8 cm, and a width of 6cm.
Answer:
192 cm^3
Step-by-step explanation:
Volume equals Area of the base times the height divided by three.
V = length * width * height

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".

Quintero said that 10, 12, 15 forms a right triangle. How can you check if the he is right,
explain and show your prove.
Answer:
Step-by-step explanation:
to prove that, that is a right triangle you use the theorem that the two shorter sides square added equals the longest side squared
so if its a right triangle then 10^2+12^2 will equal 15^2
10^2+12^2=244
15^2=225
225 does not equal 224 so that is not a right angle

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).
