Answer:
For negative sign , the graph reflects over x -axis and for 1/2 there will be a vertical compression
Step-by-step explanation:
Parent function is f(x)= x
We need to find the effect of the graph when f(x) is replaced with -1/2f(x)
When negative sign is multiplied outside f(x) like -f(x), then there will be a reflection over x-axis
When negative sign is multiplied inside f(x) like f(-x) then there will be a reflection over y-axis
When a number is multiplied outside f(x) then there will be a vertical stretch or compression
Here 1/2 is multiplied outside f(x). 
is less than 1 so there will be a vertical compression
For negative sign , the graph reflects over x -axis and for 1/2 there will be a vertical compression
The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps
Answer:
15%
Step-by-step explanation:
200,000-170,000=30,000
30,000/200,000=0.15, or 15%
