11.  y=-1/3x-4

Plug the slope into m in y=mx+b and  then plug in your point and solve for b. You get C

12.  Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9

13.   Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13

Samuel wants to use his earnings from Monday and Tuesday to buy some batteries
IrinaK [193]

Answer: There are 2 batteries which he can buy with his earnings .

Step-by-step explanation:

Since we have given that

Selling price of cans at the recycling center = $0.40 per pound

Number of pounds of cans he sold on Monday = 16.2

Number of pounds of cans he sold on Tuesday = 11.8

Total earning of Samuel is given by

(16.2+11.8)\times 0.40=\$11.2

Now, cost of battery =$5.60

So, number of batteries he can buy is given by

\frac{\text{ Total earnings}}{\text{ Cost of each battery}}\\\\=\frac{11.2}{5.6}\\\\=2

So, there are 2 batteries which he can buy with his earnings .

inn [45]

If the ratio is 6:7 the students should divide nicely into 6+7=13 parts.  Six of those parts are girls, seven of those parts are boys.

364 / 13 = 28

So 6 × 28 = 168 girls

Answer: 168

Check:

7 × 28 = 196 boys

168 + 196 = 364, good
