which of the following values would complete the ordered pair if the point is on the graph f(x)=-2x+3 (-1,___)

1 answer:

4 0

I believe the awnser would be 5. what you have to do is you plug in the -1 where the x is, remember that the 2 is a negative so that would make it a positive 2. I'm not sure if your teacher taught you this but my teacher taught us that f(x)=Mx+b is just another version of y=Mx+b.

#11 The directions on a sewing pattern say to buy an extra 12.5% of fabric to account for error. Sam needs 2.75 yards of fabric

Cloud [144]

Answer:

Step-by-step explanation:

Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

Step-by-step explanation:

Total fabric needed by Sam = 2.75

According to directions on a sewing pattern they say to buy an extra 12.5%

So, extra fabric would be: 12.5% of 2.75

Solving

Now adding 0.343 into 2.75 to get extra fabric quantity:

2.75+0.343

=3.09

Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.
