Answer:
When Finding the Y-Intercept from a Graph and Table, you are searching for the point of intersection between the equation and the y-axis. When finding the Y-Intercept from a Graph, you should find where the line from the equation crosses the y-axis. The point where the equation crosses the y-axis is the Y-Intercept.

Answer:
The student made a mistake in step 4
The length of the radius should be 6 cm
Step-by-step explanation:
Let us write each step to find the radius of a circle from its circumference
Step 1:
∵ C = 2πr
∵ C = 12π
Step 2:
Equate 12π by 2πr
∴ 12π = 2πr
Step 3:
Divide both sides by 2π
∵ 
Step 4:
∴ 6 = r
∴ The radius of the circle is 6 cm
The student mad a mistake he divided the left hand side by 2π and the right hand side by 2 only he left π with r
Step 4:
∴ 6 = πr
So he divided both sides again by π
Step 5:
∵ 
Step 7:
∴
= r
The student made a mistake in step 4
The length of the radius should be 6 cm
Answer: n>320
Explanation:
Let's solve your inequality step by step.
Step 1: Simplify both sides of your inequality
n/-8 < -40
-1/8n < -40
Step 2: Multiply both sides by 8/(-1).
(8/-1)*(-1/8n)< (8/-1)*(-40)
n>320
----Your answer is n>320.----
