Step-by-step explanation:
The slope of the above line = -2
slope of the line perpendicular to the above line = 1/2
If it passes through point (4,-3) , it's equation
A = 1, B = -2 and C = -10
A+B+C= 1+(-2)+(-10)
= 1-2-10
= 1-12
= -11
Answer:
36
Step-by-step explanation:
divide the 72 pieces by 2, you already know that 6 + 6 is 12, and 30 +30 is 60, so add 60 and 12 and you get 72

Answer:
Step-by-step explanation:
Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:
Month 1:
Gloria talked on her cell phone for . So, she had to buy 2 packages of for each package.
Hence:
Month 2:
Gloria talked on her cell phone for . So, she had to buy again 2 packages of for each package.
Hence:
Month 3:
Gloria talked on her cell phone for . So, she had to buy 3 packages of for each package.
Hence:
Then, if we take the total Gloria had to pay for the frist three months, we have:
