In this problem, you must change the signs of everything in the parenthesis, which will come to 3x^2 + x - 5x^2 - x + 4. Add like terms, and you will end up with -2x^2 + 4, which is answer choice A. Hope this helped
Answer:
22 per dog when she is walking 8
she would make 176 for walking all 8 of them
Step-by-step explanation:
For each additional dog she walks she is giving a discount. If you subtract each one you will see she is giving a 2.75 discount.
40-37.25 = 2.75
37.25-34.50 = 2.75
34.50-31.75 = 2.75
Since you know she gives a discount of 2.75 per dog you can take that times the number of dogs (8).
8 x 2.75 = 22 per dog
Then take that amount and multiply it by the number of dogs she is walking.
8 x 22 = 176 for all 8 dogs
•y-intercept is 20
•y-intercept represents how many glass bottles you need to earn $1.00 if you have 0 aluminum cans
•x-intercept is 50
•x-intercept represents how many aluminum cans you need to earn $1.00 if you have 0 glass bottles
so 3x2 equals 6 and 0 x 1 equals 0 so 0x6 equals 0 so its zero
