Do the values in the table represent a proportional relationship?
x 1 2 3 4
y 2.5 5 7.5 10
Select from the drop-down menu to correctly complete the statement.
All of the y-values a constant multiple of the corresponding x-values, so the relationship
Answers
Answer:
yes every values are increasing constantly by 2.5
Answer:
Step-by-step explanation:
Note that for each unit increase in x, y increases by 2.5. The constant of proportionality is therefore 2.5:
y = 2.5x
All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.
Consider the points (-5,2) and (3,-9)
What's the horizontal distance between the two points?
Answers
Answer:
The distance between the 2 points is about 13.6
Step-by-step explanation:
Picture the 2 points on a graph, and then look at the distance between them as the hypotenuse of a right triangle. You can easily find the length of the legs of that triangle, and with those legs, you can use the pythagorean theorem to calculate the length between the points.
The length of one leg is the distance between the 2 x-coordinates, between -5 and 3, so that's 8.
[tex]3--5=3+5=8[/tex]
The length of the other leg is the distance between the y, between 2 and -9.
[tex]-9-2=-11[/tex]
That's just a distance of 11, as there's no such thing as negative distance.
Now we have the legs, so we can find the hypotenuse:
[tex]a^2+b^2=c^2\\8^2+11^2=c^2\\64+121=c^2\\c^2=185\\c\approx13.6[/tex]
Y = 4x + 9
What is the slope and the y-intercept?
Answers
Answer:
y=4x+9 is in the form y=mx+b , so the slope ( m ) is 4 and the Y-intercept ( b ) is 9
Answer:
m = 4b = 9Step-by-step explanation:
We know that:
y = mx + by = 4x + 9If we compare these two equations, we can find the slope and the y-intercept.
=> (y = mx + b) = (y = 4x + 9)
We can clearly see that 'm = 4' and 'b = 9'.
Conclusion:
Therefore:
m = 4b = 9Hoped this helped.

Answers
Answer:
25:26
Step-by-step explanation:
You mean the ratio?
Let's simplify the speed skater first. 500 meter in 40 second to x meter in 1 second. 500/40=12.5 meters per seconds
Cheetah:260/10=26 meters per seconds
Let's make this into a integer

The price of a pair of headphones is $49.99 before tax. Ron bought the headphones for a 50% discount. He then paid sales tax of 8% on the discounted price.
Part A: How much did Ron pay in sales tax? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Ron paid for the headphones? Show all work and steps in your solution.
Answers
Answer:
A. $2.00
B. $26.99
Step-by-step explanation:
0.5 x 49.99 = 24.995
49.99 - 24.995 = 24.995
0.08 x 24.995 = 1.9996 and round to the nearest hundredth
24.995 + 1.9996 = 26.9946
round to the nearest hundredth
Answer:
Part a: 1.9996
Part b: 26.9946
Step-by-step explanation:
STEP 1:
Find the unit rate (1% of 49.99). You should get 0.4999. Then, multiply 0.4999 by 50. You should get 24.995.
STEP 2:
Find the unit rate of 24.995. You should get 0.24995. Then multiply 0.24995 by 8. You should get 1.9996 (answer for part a).
STEP 3:
Add 1.9996 to 24.995. You should get 26.9946 (answer to part b).
there is 10 fishes in a tank.
1 dies
3 swim away
4 choke on water
2 are breathing
how many fish are in the tank ?
Answers
10
It doesn't say they jumped out of the tank.
Answer:
Im not quite sure but I think it is either 10, cause it says there are 10 fish in the tank. Either that or 8 (ill explain)
Step-by-step explanation:
1 died, but that doesnt mean it was taken out of the tank. 3 swam away, but if they are in a tank they probably just swam to a different part of the tank. 4 choke on water, but that doesnt mean they didnt recover. however, the "2 are breathing" part got me confused since the definition of breathing means taking in air and expelling stuff out...fish "breathe" water so it didnt make sense. So, if you include the 2 breathing fish there are 10, but if u dont there are 8.
I really hope this helps :)

A spinner with 12 equally sized slices has 5 yellow slices, 3 blue slices, and 4 red slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow or blue slice?
Answers
The probability that the dial stops on a yellow or blue slice will be 0.6667.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A spinner with 12 similarly measured cuts has 5 yellow cuts, 3 blue cuts, and 4 red cuts. The dial is turned and stops on a cut indiscriminately.
The total number of the event is given as,
Total events = 5 + 3 + 4
Total events = 12
The probability that the dial stops on a yellow or blue slice will be given as,
P = 3 / 12 + 5 / 12
P = 0.25 + 0.4167
P = 0.6667
The probability that the dial stops on a yellow or blue slice will be 0.6667.

Answer:
x y
4/3 2
8/3 10/3
22/3 24/3
Step-by-step explanation:
Substitute y with 2 for the first problem
2=x+2/3
Subtract 2/3 on both sides:
4/3
Thus:
x y
4/3 2
Now Substitute x with 8/3 for the second problem
y=8/3+2/3
Add:
y=10/3
Thus:
x y
8/3 10/3
Now Substitute x with 8/3 for the third problem
y=22/3+2/3
Add:
y=24/3
Thus:
x y
22/3 24/3
Thus the Full equation is:
x y

8/3 10/3
22/3 24/3
