Neeeddddd HELP LOOKONG FOR ANSWERS!!

Answer:

a.) 13 students

b.) 53 members

Step-by-step explanation:

a.) In the given equation of y=4x+13, "x" represents how many years have gone by since the club had started. The number "13" in this equation represents the y-intercept, or the value of "y" when x = 0. Therefore, when "x" is 0 years, there were 13 students in the clubs, meaning that the original group that started the club contained 13 students.

b.) Since the question asks how many members that the club will have after their tenth year and you already know that "x" in the equation y=4x+13 represents the number of years since the club started, all you have to do is plug 10 in for "x" in the equation; so, the equation will now look like this: y=4(10)+13. Keeping PEMDAS in mind, you first multiply 4 and 10 to get 40, and then you add 13 to get an answer of 53 members after year 10.

Two angles form a straight angle. One angle measures 89'. What is the measure of the other angle
OleMash [197]
 A "straight angle" is a straight line.
 The angle of a straight line is 180 degrees. 
 The value of 2 angles add together to make 180
 One of the angles = 89 degrees
 The value of the second angle = 180-89 = 91
