Answer:
The value of rate of change in the equation is 37.69.
Step-by-step explanation:
Given the equation that models the total cost(T) is:
where d is the drink you purchase.
<u>To determine the rate of change</u>:
1. An equation must be into the Slope-intercept form (y=mx+b).
2. m is the slope (rate of change) of the linear function.
3. b is the y-intercept of the linear function (y- intercept is where the line crosses the y-axis).
Since, the given equation is in the linear form i.e,
The rate of change(m) of the given equation is, 37.69.
Answer: (C) It can be shown that W = x y z ∈ R 3 : x + 2y − 4z = 0 and y − 3z = 0 is a subspace of the vector space R 3 , and the dimension of W is 2.

Answer:
tan(330°) = (-√3)/3
Step-by-step explanation:
tan(330°) = tan(-30°) = -tan(30°) = -1/√3
The form with a rationalized denominator is ...
tan(330°) = (-√3)/3
Answer:
don´t ge it sorry
Step-by-step explanation:
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23
hope this helps
