Answer:
90 Degrees.
Step-by-step explanation:
90 Degrees will always form with perpendicularity.
Answer:
(2, ∞)
Step-by-step explanation:
The function is not defined to the left of x=2 (assuming the independent variable is x). There is a vertical asymptote at x=2, so the function is not actually defined for x=2. However, the function is defined for all values of the independent variable greater than 2, so that is its domain.
(We don't actually know what the indpendent variable is, so we have expressed the domain in interval notation—avoiding the problem of naming the independent variable.)
Answer: 85 student tickets, 65 adult tickets.
Let's say the # of students is x and the # of adults is y. The two equations we get are 7.50x + 15y = 1612.50 and x + y = 150
x = 150 - y
7.5(150-y) + 15y = 1612.5
1125-7.5y+15y=1612.5
7.5y=487.5
y=65
x=150-65
x=85
Hope this helps!
Answer:
Step-by-step explanation:
x^2-10x+21
(x-7)(x-3)
find the 2 numbers that when multiplied make the last number or +21 and when combined make the middle number of -10. -7*-3 = 21 and -7+-3=10
