Y^2-5=31 add 5 to both sides
y^2=36 take the square root of both sides..
y=±√36
y=±6
y=-6 and 6 so B and D is the answer.
13m-22=9m-6
13m-9m-22=-6
4m-22=-6
4m=-6+22
4m=16
m=16/4
m=4
<em>Therefore, m is 4</em>
So to compare boxes, you want to convert both to price per ounce unit.
So for smaller box, we have ratio $2.89 / 17 ounces which can be reduced to $0.17 per ounce. You just divide 2.89 by 17.
Now for larger box, we have ratio $3.29 / 24 ounces which can be reduced to approximately $0.14 per ounce. 0.137083333... to be exactly.
Larger box has smaller ratio compared to smaller box therefore larger box the is better buy.
The difference per ounce is 0.17 - 0.137083333... = 0.03291666... so that's 3.3 cents cheaper per ounce.
Final answer: <span>The larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.</span>
Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
X^3 - x^2 - 6x
x(x^2 - x - 6) =
x(x + 2)(x - 3) <===
