Answer:
x = 10 1/8 | y = 40 1/2. | z= 30 3/8
Step-by-step explanation:
x + y + z = 81
4x = y
3x = z
x + 4x + 3x = 81
8× = 81
÷8. ÷8
x = 10 1/8
4x = y
(10 1/8) (4) = y
40 1/2 = y
3x = z
(3) (10 1/8) = z
30 3/8 = z
Answer:
12, 14
Step-by-step explanation:
To find out a distance, you must find out how far numbers are, you can use a number line for this.
Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get
<span>20<span>x3</span>−3<span>x2</span>+6=0
</span><span>
This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
Answer:
Bedroom 1 and 2
Step-by-step explanation:
The area of Bedroom 1 is 121, which is less than 132.
The area of Bedroom 2 is 120, which is also less than 132.
The area of Bedroom 3 is 169, which is more than 132.
3x - 12 = 5
3x = 12 + 5
3x = 17
x = 17/3
