Answer: Lower right corner
============================================
Explanation:
The information that the temperature rises 3 degrees per hour will tell us the slope here. The slope is rise/run = 3/1 = 3. Each time we move up 3 on the y axis, we move 1 spot to the right.
As you can see in the bottom right hand corner graph, we start off at a temperature of 20 degrees. This is the point (x,y) = (0,20)
Then one hour later (x = 1), the temperature y bumps up to y = 23. Another hour passes by (x = 2) and y becomes y = 26. And so on.
Answer:
1) convert these words into 2 equations:
x+y=6
y=x+4
1) for the first equation graph by intercepts:
x intercept: x+0=6
x=6
y intercept: 0+y=6
y=6
hence put point (0,6) and (6,0) on the graph
2nd equation:
graph by slope intercept: go to (0,4) on the graph. go up one and over one to the right. You should end up at (1,5)
so graph (0,4) and (1,5)
hope this helps
4n-2n+4=-1+17
2n+4=-1+17
-1+17=16
2n+4=16
Move + 4 to the other side. Sign changes from +4 to -4
2n+4-4=16-4
2n=12
Divide by 2 for 2n and 12
2n/2=12/2
n=6
Check answer by using substitution method
4(6)-2(6)+4=16
24-12+4=16
12+4=16
16=16
Answer : n=6
