Consider the table:
Input value Output value
0 0
1 1
2 4
3 9
Which statements are true? Select all that apply.
The graph of the function will not form a straight line, so it is nonlinear.
The function is not proportional.
The function goes through the origin.
The difference between consecutive output values is a constant.
Answer:
1st 2nd and 3rd box
Step-by-step explanation:
1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)
2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)
3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin
4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.

PLEASE HELP ASAP WILL GIVE BRAINLIEST TO BEST ANSWER
Help please ASAP!! I will give brainliest!
Answer:
3/5 1/10
Step-by-step explanation:
1/5 divided by 1/3 is 1/5 times 3 which is 3/5
1/2 divided by 5
= 1/2 divided by 5/1
=1/2 times 1/5
=1/10
Answer: 1) 3/5 2) 1/10
Step-by-step explanation:
1) 1/5 divided by 1/3
then you take the reciprocal so the equation is now 1/5 times 3/1
and you get an answer of 3/5
2) 1/2 divided 5/1 (you put the one under the 5 cuz it's a whole number)
Take the reciprocal of the second fraction and flip the numerator and denominator so you get 1/5.
Then, do 1/2 x 1/5 which equals 1/10.
Hope that helped! :)

Pls need help due in 20 mins- n no mfkn links pls pls plsss
Answer:
B
Step-by-step explanation:
speed is determined by the gradient
car 1 gradient = change in y / change in x = [tex]\frac{85 - 75}{17 -15} = \frac{10}{2} = 5[/tex]
car 2 gradient = 10
so car 2 is travelling faster than car 1
Solve the system using addition. Use pencil and paper. Explain why the addition method is a good choice for solving the system. If you wanted to solve for x first, is the addition method still a good choice? Explain.
x-2.5y=12.5
-x+2.3y=11.9
Answer: the answers are x = -292.5 and y = -122
Step-by-step explanation:
Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.
For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.
After that, we get the 2 equations as
2.3x-5.75y = 28.75
-2.5x+5.75y = 29.75
then by adding the 2 equations we get
-0.2x = 58.5
and by dividing 58.5 by -0.2 we get
x = -292.5
substituting the value of x in any equations above we get
y = -122

Ricardo bought 6 pounds of peanuts at the local wholesaler for $12. His friend Saniya bought 4 pounds of peanuts at the supermarket for $10. Saniya thinks she got the better deal because $10 is less than $12.
How much did Ricardo pay per pound?
How much did Saniya pay per pound?
Who got the better deal?
A. Ricardo
B. Saniya
C. They paid the same rate per pound.
Answer:
ricardo
he payed 2 per pound while she payed 2.50
Answer:
Ricardo
Step-by-step explanation:
Divide $12 by 6 pounds and then divide $10 by the 4 pounds.
Ricardo got 2$ per pound and Roxanne got 2.5$ per pound so Ricardo got the better deal.
What is the volume of the pyramid?
I will report if you send links
Answer:
The answer is 1133.33 i got it from go ogle so blame me if i got it wrong blame go ogle can i have Brainliest
Step-by-step explanation:
Answer:
66 2/3
Step-by-step explanation:
The way to solve this is The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid. Note: The volume of a pyramid varies slightly depending on the polygonal base.
What i did was i first tried to do 17 x 20 x 10 which game 3400 but when i remembered that V=1/3 x base area x height which would be 1/3 x 17 x 20 = 113 1/3 but if the base was 10 it would be 1/3 x 10 x 20 = 66 2/3. so i think the base is 10 and the answer would be 66 2/3
If i am wrong i'm sorry
Help The first one is what is on sale and the bottem is what needs to be solved!
Answer:
jacket 80
shoes 32 and 16
shirt 9 , 8.04, 4.08
Step-by-step explanation:
you need to multiply the original cost by the percentage off and then subtract from the original
example
Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40. but you would have to subtract the 40 from 120 giving you 80
