A line has a slope of –3/2 and has a y-intercept of 3. What is the x-intercept of the line?
san4es73 [151]
Slope = -3/2, b = 3
so
y = -3/2x + 3
x-intercept when y = 0 
so
-3/2x + 3 = 0
-3/2x = -3
      x = -3 *(-2/3)
      x = 2

A total of 626 tickets were sold for the school play. They were either adult tickets or student tickets. There were 74 fewer stu
Sholpan [36]

Answer:

351 adults and 275 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 626 tickets were purchased, then s+a=626.

We also know that 74 fewer student tickets then adult tickets. So s+76=a, the number of student tickets plus 76 will be the number of adult tickets.

We will solve by substituting one equation into the other. We substitute a=76+s into s+a=626. Simplify and isolate the variable a.

s+a=626

s+76+s=626

2s+76=626

2s+76-76=626-76

2s=550

s=275

This means that 275 students attended and 351 adults attended since 275+351=626.
