I had to do this and it’s fake, my whole class got it wrong even though we all put the right answer so ya
Benny started with 55 five cards. In order for his dog to have eaten half his cards and end up with 30 cards, that would mean he had 60 cards. Mind you, he had bought 5 more the day before his dog ate them. I hope that makes sense

Step-by-step explanation:
<u>Step 1: Define</u>
-12(x + 4) + 14x = 60
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -12: -12x - 48 + 14x = 60
- Combine like terms: 2x - 48 = 60
- Add 48 to both sides: 2x = 108
- Divide 2 on both sides: x = 54
Answer: -1.13
Step-by-step explanation:
Look at the coefficient of x², ignore the positive or negative sign. The larger the coefficient, the narrower the graph.
in this case, the coefficients are -2, -1/2, -4, and 1/7
ignore the positive or negative sign, 4 is the largest number, so y=-4x² is the narrowest.
Note: the positive/negative sign tells you whether the graph opens upward or downward. It doesn't determine the width of the graph.
