Answer:
67 units^2
Step-by-step explanation:
The surface area of the prism is found by
SA = 2 ( lw+lh + wh)
= 2 ( 5*1.5+ 4*1.5 + 5*4)
= 2 ( 7.5+6+20)
= 2 (33.5)
= 67
Answer:
y = - 27/5
Step-by-step explanation:
4(3) - 5y = 39
12 - 5y = 39
-5y = 39 - 12 = 27
y = - 27/5
So if you're adding two negatives you move left, positive you move right, and when you have to determine a negative, and a positive you just have to see which one is the farthest from zero which the farthest one's sign is either positive, or negative. Positive to move right, and negative to move left.
Y=Mx+b (m is slope, b is y-intercept)
Answer:
Step 3, because the solution should also include all the values for x between the two given values
Step-by-step explanation:
step 1
we have
![y_1=\left|x-4\right|](https://tex.z-dn.net/?f=y_1%3D%5Cleft%7Cx-4%5Cright%7C)
![y2=1](https://tex.z-dn.net/?f=y2%3D1)
step 2
The graph in the given problem
step 3
Identify the solution when ![y1\leq y2](https://tex.z-dn.net/?f=y1%5Cleq%20y2)
so
![\left|x-4\right|\le1](https://tex.z-dn.net/?f=%5Cleft%7Cx-4%5Cright%7C%5Cle1)
using a graphing tool
The solution is the interval -----> [3,5]
see the attached figure
All real numbers greater than or equal to 3 and less than or equal to 5
therefore
The first step in which the student made an error is step 3
