Answer:
sorry whats the question
Step-by-step explanation:
Answer:
The slope is 3
Step-by-step explanation:
For this, you do y2-y1 over x2-x1
In this case, 12-0 and 4-0, leaving you 12/4, which is 3.
Hope this helps!
Answer:
Step-by-step explanation:
<u>According to data in the table we see pairs of points:</u>
<u>This gives us the rate of change:</u>
- (125 - 75)/(5 - 3) = 50/2 = 25
<u>The y - intercept is zero:</u>
- 75 = 3*25 + b
- 75 = 75 + b
- b = 0
<u>The line is:</u>
This is the line on the graph B
<u>Note.</u> <em>Its not clear what is needed regarding the table on the bottom</em>
Answer:
Step-by-step explanation:
㏒ 3+㏒(x+2)=1
㏒3(x+2)=1
3(x+2)=10^1
3x+6=10
3x=10-6=4
x=4/3
so A
3.
