Answer: The first and last table.
As the x increases by 2, the y goes down by 1, so both tables have the same rate of change which means they are the same function.
Tables 1 and 5 are equal.
Given are 5 tables in x and y with two values each.
We are to find out which two represent the same function.
As for every function, two points are given.
Let us compare the slopes of each function.
Slope=change in y coordinate/change in x coordinate
Table Slope
I -0.5
2 -0.5
3 -0.5
4 1
5 -0.5
Table 4 is eliminated now.
Though slopes are the same for 1 and 2,f(4) =8 and 5 different . Hence I and II cannot be the same. Similarly for 2 different values are there in table 3,4,5. Hence 3,4,5 cannot be pairwise equal.
We find that table I and table 5 have the same slope. Also when pairwise taken, (4,8) and (2,9) slope = -0.5
So table I = table 5
Hope this helps... Stay safe and have a great day/night!!! :D

Juan needs to simplify the fraction LaTeX: \frac{32}{52}32 52. He will need to divide the numerator and the denominator by the greatest common factor. What is the greatest common factor of 32 and 52?
Answers
Answer:
4Step-by-step explanation:
Given the expression, 32/52
Juan need to divide the numerator and the denominator by the greatest common factor
For 32;
32 = 8 * 4
For 53
52 = 13 * 4
Find the ratio
32/52 = (8*4)/(13*4)
32/52 = 8/13
Since 4 is common to both factors, Hence the greatest common factor is 4

Which equation does not represent a direct variation? Explain.
Answers
Answer:
y = 3x + 2
Step-by-step explanation:
"When x is zero in a direct variation equation y will also be zero. ... Equations of the form y = kx + b where b is a number other than zero are not direct variation equations because when x is zero in any of these y is not zero. Normally direct variation equations are written as y = k•x or just y = kx."
in short, y = 3x + 2 can't be turned into y = kx
you could also immediately tell it's y = 3x + 2 because it includes + 2
In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8. Many pundits claim that the worst is yet to come, with an earthquake 133,680 times as intense as the 1989 earthquake ready to hit San Francisco. If the pundits ability to predict such earthquakes were correct, what would be the magnitude of their claimed earthquake? Round your answer to the nearest tenth.
Answers
Answer:
Magnitude of claimed earthquake = 10.363 (Approx)
Step-by-step explanation:
Magnitude of claimed earthquake = log√133,680 + 7.8
Magnitude of claimed earthquake = [1/2] log 133,680 + 7.8
Magnitude of claimed earthquake = 2.563 + 7.8
Magnitude of claimed earthquake = 10.363 (Approx)

Answers
Answer:
One way of awarding interest is called simple interest. Before we provide the formula used in calculating simple interest, let’s first define some basic terms.
Balance. The balance is the current amount in an account or the current amount owed on a loan.
Principal. The principal is the initial amount invested or borrowed.
Rate. This is the interest rate, usually given as a percent per year.
Time. This is the time duration of the loan or investment. If the interest rate is per year, then the time must be measured in years.
To calculate the simple interest on an account or loan, use the following formula.
Simple Interest
Simple interest is calculated with the formula
I=Prt,
where I is the interest, P is the principal, r is the interest rate, and t is the time.

At the baseball game, the Gregory's bought 5 hot dogs and 2 hamburgers and paid $27.00. The Hart's purchases 3 hot dogs and 4 hamburgers and paid $29.50. How much does 1 hot dog cost?
Answers
Answer:
1 hot dog costs $3.50
Step-by-step explanation:
Represent Hot dog with x and Hamburger with y
Gregory's purchase:
[tex]5x + 2y = 27[/tex] --- (1)
Hart's purchase:
[tex]3x + 4y = 29.5[/tex] ---- (2)
Required
Find x
To do this, we'll make use of the elimination method of solving simultaneous equation.
Start by multiplying (1) by 2
2 * ([tex]5x + 2y = 27[/tex])
This gives:
[tex]10x + 4y = 54[/tex] ---- (3)
Subtract (2) from (3)
[tex]10x + 4y = 54[/tex]
- ([tex]3x + 4y = 29.5[/tex])
-------------------------
[tex]7x = 24.5[/tex]
Solve for x
[tex]x = \frac{24.5}{7}[/tex]
[tex]x = 3.5[/tex]
Hence:
1 hot dog costs $3.50
When p = 12, t= 2, and s = 5. r = 18. If r varies directly with p and inversely with the product of s and t, what is the constant of variation? O col 1 2 O O 18
Answers
Answer:
Constant of variation is: 15
Step-by-step explanation:
r varies directly with p and inversely with the product of s and t
It can be written as:
r ∝ p/st
When the proportionality symbol is removed, a constant is introduced which is called constant of variation
So
[tex]r = \frac{kp}{st}[/tex]
Putting p = 12, t= 2, and s = 5 and r = 18
[tex]18 = \frac{k * 12}{2*5}\\18 = \frac{12k}{10}\\12k = 18*10\\12k = 180\\\frac{12k}{12} = \frac{180}{12}\\k = 15[/tex]
Hence,
Constant of variation is: 15
