Answer:
A. (0, 60)
B. 15x
Step-by-step explanation:
The initial value is the same as the y-intercept, which is 60 or (0, 60).
The rate of change would be the same as the slope. To find the slope, you do rise/run. You move 15 units up, and 1 to the right. That would be 15x.
Hope this helps!
Answer:
128 square inches
Step-by-step explanation:
The scale factor for area is the square of the scale factor for side length. The larger octagon has an area of ...
(8/4)²(32 in²) = 4·32 in² = 128 in²
The area of octagon B is 128 square inches.
Answer:
Step-by-step explanation:
Since all the answers are 100s I assume the sizes are 10, 10 and 20.
This would mean there are 2 sides of 10x10 and 4 of 10x20
The total area would be 2*100+4*200=1000. Since that's obviously not one of the answers. We can assume it's probably 15 since it should give us a full 100 number. We know the other two are probably 10 due to their sizes and them obviously being two digits. This would mean it would be 2*100+4*150=800
