Answer:
y = 2x - 5
Step-by-step explanation:
-5 because its the y-intercept where the line intercepts the y-axis
2x because it is your slope (the line jumps two units vertically every one unit horizontally)
Try putting letter D because the lines and dark/ dashed mean if it’s greater than or equal to
It will take 6 months
Equation: 200+75m=350+50m
m=months=6
Work shown:
200+75*6=650
350+50*6=650
Answer:
- A(1) = -4
- A(n) = A(n - 1) - 6
Step-by-step explanation:
<h3>Given</h3>
- AP with the explicit formula A(n) = 8 - 6(n - 1)
<h3>To find </h3>
<h3>Solution</h3>
<em>Recursive formula is the formula A(n) = A(n - 1) + d</em>
<u>Based on the explicit formula we have:</u>
- A(n) = 8 - 6(n - 1) = 8 - 6n + 6 = 2 - 6n
- A(n - 1) = 2 - 6( n - 1) = 2 - 6n + 6 = 8 - 6n
<u>The common difference is:</u>
- d = A(n) - A(n - 1) = 2 - 6n - (8 - 6n) = 2 - 6n - 8 + 6n = - 6
<u>The first term is:</u>
- A(1) = 2 - 6(1) = 2 - 6 = -4
<u>So the recursive formula is:</u>
- A(1) = -4
- A(n) = A(n - 1) - 6
The correct answer is 12 teeth
Explanation:
The ratio represented by the diagram is 6:1 or 6/1, this means, for each 6 teeth in the larger gears there is only 1 in the smaller gear. Now, to find the number of teeth if the larger gear is 72 the best is to use cross multiplication. The process is shown below:
1. Write the known values, and use x to represent the value missing
2. Use cross multiplication, and then division to find x
3. Solve the operation
