Xavier had some basketball cards. He purchased 7 more. Write an expression describing the total amount he had.

Total amount = b + 7

Step-by-step explanation:

Let the number of basketball cards that he had be represented b

He purchased 7 more.

Hence, an expression describing the total amount he had is written as:

Total amount = b + 7

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
