If it's expanding 8m per minute, then you have to multiply 8 by 26.
1 minute = 8 m
2 minutes = 16 m
5 minutes = 40 m
10 minutes = 80 m
26 minutes = 208
8 * 26 = 208
So when it reaches 26 m in length, it'll be expanding 208m per minute.
Answer:
-1y + z
Step-by-step explanation:
2y + z - 3y [Given Expression]
-1y + z [Combine like-terms]
The perpendicular bisector would be the line that connects with the line HI at a 90 degree angle and in the mid-point. This means that we would have to find the slope of the line HI and take the opposite. The slope of HI is 1/3. This means that the slope of the perpendicular line is -3. Now we must solve for the line that crosses through the midpoint. y=mx+b we know that m=-3 and that the midpoint is at -1,3 so x=-1 and y=3. 3=(-3)-1+b. We then solve for b and find it to be 0. So the final answer is y= -3x
70+74+87+85 = 316
For the 5th test score, an 80 average needs 400 as the total score. So 400-316 = 84 on the next test.
