Answer:
- 3 ounces of 75%
- 7 ounces of 45%
Step-by-step explanation:
Let x represent the number of ounces of 75% silver needed. Then (10-x) is the number of ounces of 45% silver. The total silver required is ...
0.75x +0.45(10 -x) = 0.54(10)
0.30x +4.5 = 5.4
0.30x = 0.9
x = 0.9/0.3 = 3 . . . . . ounces of 75% silver
10-x = 7 . . . . . ounces of 45% silver
Luis needs 7 ounces of 45% silver and 3 ounces of 75% silver.

Answer:
The answer is "
"
Step-by-step explanation:
Given value:
![\to \bold{ \sqrt[3]{x^5y} }](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B%20%5Csqrt%5B3%5D%7Bx%5E5y%7D%20%7D)
![\to \sqrt[3]{x^5y} =(x^5y)^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Cto%20%5Csqrt%5B3%5D%7Bx%5E5y%7D%20%3D%28x%5E5y%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
formula:
The final value is: 
Answer:
B. y=x²-x-6
Step-by-step explanation:
Consider the product ...
0 = (x -a)(x -b) = x² -(a+b)x +ab
This equation has solutions x=a and x=b. You will note that ...
- the constant is the product of the solutions (ab)
- the coefficient of x is the opposite of their sum (-(a+b))
For solutions of -2 and 3, the constant will be (-2)(3) = -6. This eliminates choices C and D.
The sum of the solutions is -2+3 = 1, so the coefficient of x is -1, matching choice B.
