Answer:
m = -5 + 2b
Step-by-step explanation:
2b - m = 5
<u>-2b -2b</u>
<u>-m</u> = <u>5 - 2b</u>
-1 -1
5 ÷ -1 = 5
-2b ÷ -1 = 2b
m = -5 + 2b
Answer:
y - 1 = 1/6x + 1 <<< Point slope form
y = 1/6x + 2 <<< slope intercept form
Either one works unless the question specifies the form of the equation
Step-by-step explanation:
Point slope form: (y - y1) = m(x - x1)
Given: (-6,1) ; m = 1/6
(y - 1) = 1/6(x - (-6))
y - 1 = 1/6x + 1 <<< Point slope form
y = 1/6x + 2 <<< slope intercept form: y = mx + b
Answer:
120
Step-by-step explanation:
We are given that the function for the number of students enrolled in a new course is 
.
It is asked to find the average increase in the number of students enrolled per hour between 2 to 4 hours.
We know that the average rate of change is given by,
,
where f(x)-f(a) is the change in the function as the input value (x-a) changes.
Now, the number of students enrolled at 4 = f(4) = 
= 255 and the number of students enrolled at 2 = f(2) = 
= 15
So, the average increase 
= 
= 
= 120.
Hence, the average increase in the number of students enrolled is 120.
Answer:
50 degrees
Step-by-step explanation:
If angle A and angle B are complementary, that would mean that their sum is 90 degrees. A + B = 90 . We know that angle A is 40, so 40 + B = 90. It becomes a one step equation. Subtract both sides by 40. 90 - 40 = 50. Angle B is equal to 50 degrees.
<span>To solve, just think, what times 4 equals 12?
4*3 = 12
Therefore, multiply both sides by 3.
3*3 = 9 and 4 *3 = 12
9/12 is the final answer</span>
