9(-7b-6)

-63b-54

What I did was multiply 9 by -7b to gt -63b. Then, I multiplied 9 by -6 to get -54. :) hope this helps

Andreyy89

Answer: k = 55 degrees

Step-by-step explanation:

to find J, subtract 122 from 180, you get 58. The total number of degrees is 180. Since L is given as 67, and 67+58=125. Simply subtract 125 from 180 which is 55 degrees

Hayden had 2 and 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a

Flauer [41]

Answer:

7/8 of a gallon

Step-by-step explanation:

First find a common denominator for each of the values, in this case eighths. Next, add the total water used for the tomatoes and peppers (you'll get 7/8 gallons). Then, convert the 2 and a half gallons to eighths, getting 20/8 of a gallon. Next, subtract the 7/8 from the 20/8; getting 13/8. Since you need to find the amount of water used for the lettuce, subtract the last value from 3/4 gallons (or 6/8)

Determine the slope of the line that is perpendicular to the line y = -7x - 12.

Mnenie [13.5K]

Answer:

None of these answers are correct.

Step-by-step explanation:

Perpendicular lines have opposite and reciprocal slopes, which means that we take the slope and we flip it. After we've done that, we change the sign.

Since the original slope is -7, first we flip it and get -1/7. Now we change the sign and get 1/7. Therefore, the perpendicular slope of this line would be 1/7
