A scale factor of 3.5 maps Figure A onto Figure B. There is two triangles, Figure A is 5, Figure B is x. Whats the value of X?

X = 17.5

Step-by-step explanation:

Here we have a word problem relating to syntax regarding mapping of a scale factor;

Whereby the scale factor is 3.5 we have that the scale factor can be represented as 2:7

Hence the scale is for every 2 units of Figure A, we have 7 units of Figure B

Hence where Figure A is 5, we have;

2 unit of Figure A = 7 units of Figure B

∴ 1 unit of Figure A = 7/2 (=3.5) units of Figure B

5 unit of Figure A = 3.5 × 5 units of Figure B = 17.5 units of Figure B

Therefore where we have;

5 unit of Figure A = X units of Figure B

Then, X = 17.5.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
