Consider the inequality x > - 1.5. determine whether each value of x makes this inequality true
musickatia [10]

9514 1404 393

Answer:

  no, yes, yes, no, yes

Step-by-step explanation:

You're looking for values greater than -1.5. All positive numbers will be greater than any negative number.

The two negative numbers among the answer choices are both to the left of -1.5 on the number line. They are less than -1.5, so are <em>not</em> greater than -1.5.

The negative numbers are No; the positive numbers are Yes.

Violet bought 120 greeting cards at 3 for $2. Harry bought the same
Paul [167]

Step-by-step explanation:

Violet bought 120 at "3 for $2".

how many groups of 3 did she buy ?

120/3 = 40 groups of 3.

so, she paid 40×2 = $80.

Harry bought 120 at "6 for $5".

how many groups of 6 did he buy ?

120/6 = 20 groups of 6.

so, he paid 20×5 = $100.

that means Violet paid 100 - 80 = $20 less than Harry.

1. Determine the degree of homogeneity of the function S(x,y) = x^2 y + xy^2, and show that Euler's Theorem holds. 24 zvy
Dmitrij [34]

Answer:

Degree k=3

Step-by-step explanation:

The function that you have is a homogeneous function of degree k=3. In fact, if \lambda \in \mathbb{R} and (x,y) \in \mathbb{R}^{2} we have that:

s(\lambda x, \lambda y)=(\lambda y)(\lambda x)^{2}+(\lambda x)(\lambda y)^{2}=\lambda^{3}x^{2}y+\lambda^{3}xy^{2}=\lambda^{3}s(x,y)

To verify that the Euler Theorem holds we need to show that:

x\frac{\partial s}{\partial x}+y\frac{\partial s}{\partial y}=3 s(x,y).

To do that let's compute the partial derivatives:

\frac{\partial s}{\partial x}=2xy+y^2

\frac{\partial s}{\partial y}=x^2+2xy

Then,

x\frac{\partial s}{\partial x}+y\frac{\partial s}{\partial y}=2x^{2}y+xy^{2}+yx^{2}+2xy^{2}=3xy^{2}+3x^{2}y=3(x^{2}y+xy^{2})=3s(x,y).
