pls explain why and how the answer u got is proportional
Answer:
A
Step-by-step explanation:
This is because to find out if a table is proportional you have to do y divided by x. Whatever table has the same answer on all of the table sections when you divide y by x, that is proportional.

Frank is 6 years older than his brother Joe. The sum of their ages is 38. How old is Joe AND Frank?
Answer:
Joe is 16, Frank is 22
Step-by-step explanation:
To find the solution to this problem, we first divide 38 by two.
38 / 2 = 19.
Then, we subtract 6 from 19 and have 19 and 13. Obviously, 19 is 6 more than 13 (19 - 13 = 6). Now, we need to make sure our number on the left is always 6 more than the number on the right. 19 + 3 = 22, 13 + 3 = 16. Since Frank is older than Joe by 6 years, we get 22 and 16 as their ages.
Can two obtuse angles be supplementary? Why or why not?
Answer:
No.
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180.
Let us consider the least obtuse angle, i.e., >90
Say 91 and add it to itself.
91+91 =182
This is >180
Hence, two obtuse angles can never be supplementary.

Answer:
B, C, D, F
Step-by-step explanation:
if you know the length and width of the traffic jam is (F and C) you can start to calculate how many cars are stuck in it. then by using how long the vehicles are and how long the space between them is you can find out how many cars would fit in this area. (B and D)
A and F are irrelevant because the question is simply asking how many vehicles in the jam not how many people or what cuased it.

Three friends decide to rent an apartment and split the cost evenly. they each paid $640 towards the total move in cost of first and last month's rent and a security deposit. if rent is $650 per month, how much was the security deposit? a. $10 b. $207 c. $620 d. $1,270
The total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.
What is a monthly payment?The monthly payment is the amount which is required to pay each month to pay off the borrowed principal amount or the rent of a service charged monthly.
The rent of the apartment is $650 per month. The rent for the two months (first and last) is,
[tex]\rm M = 2\times 650\\\\M =1300[/tex]
This rent is paid by three friends. Thus, the amount which is paid by an individual friend is,
[tex]\rm P=\dfrac{1300}{3}\\\\P=433.33[/tex]
They each paid $640 towards the total move-in cost of first and last month's rent and a security deposit. Therefore,
[tex]\rm P=640-433P=206.67\\\\[/tex]
Thus, $206.67 is paid by each of them towards security deposits. The total amount of security deposit, deposited by 3 of them, is,
[tex]\rm SD=206.67\times 3\\\\SD=620.01[/tex]
Hence, the total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

A. (x,y)→(−x,−y)
B. (x,y)→(–y,–x)
C. (x,y)→(y,−x)
D. (x,y)→(−x,y)
Answer:
D. (x,y)→(−x,y)
Step-by-step explanation:
Reflecting OVER the Y axis means it will end up on the other side of the Y axis line. The Y coordinates remain unchanged while the X coordinates invert. Attaching a crude diagram to help you picture it.
how would I rewrite, 7x - 14y= -56 into slope-intercept form?
Answer:
[tex]y =\dfrac{1}{2}x+4[/tex]
Step-by-step explanation:
Slope-intercept form: y =mx +b
7x - 14y = -56
Step1 : subtract 7x from both sides
[tex]-14y = -7x - 56[/tex]
Step2: now divide both sides by (-14)
[tex]y =\dfrac{-7}{-14}x -\dfrac{56}{-14}\\\\y = \dfrac{1}{2}x+ 4[/tex]
Answer:
y = [tex]\frac{1}{2}[/tex] x + 4
Step-by-step explanation:
7x - 14y = - 56 ( subtract 7x from both sides )
- 14y = - 7x - 56 ( divide through by - 14 )
y = [tex]\frac{-7}{-14}[/tex] x - [tex]\frac{56}{-14}[/tex]
y = [tex]\frac{1}{2}[/tex] x + 4 ← in slope- intercept form

Find the GCF of 60, 96, and 156.
Answer:
GCF = 12
for the values 60, 96, 156
Step-by-step explanation:
Solution by Factorization:
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
The factors of 156 are: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
Then the greatest common factor is 12.
A) Convert the exponential function, 12^3=x^4 y^3 z^6, to its corresponding logarithmic function.
B) Write the log form from Part A into the expanded log form. **expression must be fully expanded for full credit**
The logarithmic function is ㏒ 12³ = ㏒ x⁴ · y³ · z⁶. The equation into the expanded logarithmic form is 3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z.
How to apply logarithms on a exponential function
Logarithms are the reciprocal of exponential functions. In this question we must apply logarithms and its properties to obtain a linear-like expression in the following lines. The logarithm properties are summarized below:
㏒ₐ (b/c) = ㏒ₐ b - ㏒ₐ c (1)
㏒ₐ (b · c) = ㏒ₐ b + ㏒ₐ c (2)
㏒ₐ bⁿ = n · ㏒ₐ b (3)
a) To obtain the corresponding logarithmic function we apply logarithms on both sides of the expression:
㏒ 12³ = ㏒ x⁴ · y³ · z⁶ (4)
The logarithmic function is ㏒ 12³ = ㏒ x⁴ · y³ · z⁶. [tex]\blacksquare[/tex]
b) The expanded logaritmic form of (4) consists in the addition and subtraction of logarithms of non-power numbers, whose formed could be found, if possible, by logarithm properties:
㏒ 12³ = ㏒ x⁴ · y³ · z⁶
㏒ 12³ = ㏒ x⁴ + ㏒ y³ + ㏒ z⁶
3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z
The equation into the expanded logarithmic form is 3 · ㏒ 12 = 4 · ㏒ x + 3 · ㏒ y + 6 · ㏒ z. [tex]\blacksquare[/tex]

The State Board of Education has $1,742 to buy new calculators. If each calculator costs $2, how many calculators can the board buy?
Answer:
871
Step-by-step explanation:
The State Board of Education can buy 871 calculators with the available budget.
Here, we have to find out how many calculators the State Board of Education can buy,
We have to divide the total amount they have ($1,742) by the cost of each calculator ($2):
So, we get,
Number of calculators = Total amount / Cost per calculator
Number of calculators = $1,742 / $2
Number of calculators = 871
So, the State Board of Education can buy 871 calculators with the available budget.

4. y=3√2 and x=36
Step-by-step explanation:
Here,
interior angle of triangle = 180°
So, 90°+45°+45°=180°
Therefore, the triangle is isosceles triangle
So,
y=3√2 (the corresponding sides of corresponding angle of isosceles triangle are equal)
Again, x^2=(3√2)^2 + (3√2)^2
or, x= √(18 + 18)
or, x=√36
or, x=6
