There are 2 methods you are taught in Middle School.
Elimination and Substitution.
Answer:
1480
Step-by-step explanation:
26 / 7 is 3.7. 2 x 3.7 = 7. 400 x 3.7 = 1480
The answer would be Acute angles
Answer:
72.175
Step-by-step explanation:
The first step is subtract 94.68 by 49.67 which would be 45.01
The next step would be to use 45.01 and divide by two
The last step would be subtract 94.68 by 22.505 and you would get 72.175
Therefore your answer would be 72.175
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.
