My understanding is that the 2 angles add up to 180 degrees, so 9x+9y-54=180. Also, 9x=90 and 9y-54=90. 9x=90, so x=10. 9y=90+54. 9y=144. y=16.
A.) 2a+6b
Explanation:
multiply each term in parentheses by 2
2a+2x+3b
calculate the product
2a+6b
Answer:
No, because one x-value corresponds to two different y-values.
Step-by-step explanation:
Given a function where x represents an input of a particular value, which gives an output for that particular value inputted as defined by the function, if the function is true and valid, a particular value of input should not give us different values of output.
Thus, from the table given, at x = 5, we have y = 3.
Also, at x = 5, we have y = 2.
Here, one x-value is given us two different y-values. This is not true if a function. We cannot regard the table given as representing a function.
Therefore, the answer is:
No, because one x-value corresponds to two different y-values.
