I saw this question on Khan Acendamy go there and it will help uu!
Good afternoon/evening.
-4^4 = four to the fourth power = (-4)(-4)(-4)(-4) = 256
Remember, when a negative is multiplied by a negative it equals a positive.
It is given in the question that
Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red bricks cost $0.58 each. She can spend up to $200 on her project, and wants the number of red bricks to be less than half the number of gray bricks.
Maximum she can spend is $200. That is
![0.45x + 0.58y \leq 200 \\ y< \frac{1}{2} x](https://tex.z-dn.net/?f=0.45x%20%2B%200.58y%20%5Cleq%20200%0A%5C%5C%20%20y%3C%20%5Cfrac%7B1%7D%7B2%7D%20x)
And
![x\geq 0 , y \geq 0](https://tex.z-dn.net/?f=x%5Cgeq%200%20%2C%20y%20%5Cgeq%200)
And that's the required inequalities .
