To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple x - values
A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.
B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3
C. isn't because the x - value 2 has two values. Again, that makes this invalid.
D. is invalid because there is two x - values for 2.
Therefore, the answer is B.
Larry ran 2.52 killometers. Since a meter is 0.001 killometers, you have to do 0.001 x 220 which is 0.22 then do 2.3 + 0.22 and get 2.52.
Answer:
Question 2) 96 Question 3) 246
Step-by-step explanation:
Question 2:
The area of one side of the square is 4x4 which is 16 then you know a cube has 6 sides so 16x6 which is 96.
Question 3:
Well we know the two sides are squares with 3x3 which is 9 and then there are two so 9x2 which is 18
Then the front side with dimensions of 19x3 which is 57 and we know there are 4 sides so we do 57x4 which leads us to 228
Then we add 18 and 228 to find 246

Answer:
90 feet
Step-by-step explanation:
Because the infield of a baseball field is a square, the distance between each set of bases is equal.
P = 2l + 2w
360= 2(90) + 2w
360 = 180 + 2w
180 = 2w
90 = w
