Answer:
Step-by-step explanation:
25.
Combine like terms.
4t+7=-33
subtract 7 from both sides
4t=-40
divide both sides by 4
t=-10
26.
Subtract 2a from both sides
5=7a-16
add 16 to both sides
21=7a
divideby 7 on both sides
a = 3

Answer:
$2.34
Step-by-step explanation:
7.76+4.50+1.90+1.90+1.60=17.66
20-17.66=2.34
Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate
hypotenuse = 1 (because it is the radius of the unit circle)
sec (theta) = 1 / (-3/5) = - 5/3
cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate
cot (theta) = -3/5 / y
y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5
Third quadrant => y = -4/5
=> cot (theta) = (-3/5) / (-4/5) = 3/4
Answer:
Step-by-step explanation:
total cost = c
students = s
cost = 7
c = s*7
independent is s
dependent is c
