x + .15(8) = .50(8+x)

x + 1.2 = 4

.50x + 1.2 = 4

.50x = 2.8

x = 2.8/.50

x = 5.6 quarts

Use the identity (x+y)(x2−xy+y2)=x3+y3 to find the sum of two numbers if the product of the numbers is 10, the sum of the square

professor190 [17]

Answer:

The sum of two numbers is 7.

Step-by-step explanation:

Given : the product of the numbers is 10, the sum of the squares of the numbers is 29, and the sum of the cubes of the numbers is 133.

Using identity $(x+y)(x^2-xy+y^2)=x^3+y^3$ and given details, we have to find the sum of two numbers.

Since, given that the product of the numbers is 10 that is $xy=10$

Also, given the sum of the squares of the numbers is 29 that is $x^2+y^2=29$

and the sum of the cubes of the numbers is 133 that is $x^3+y^3=133$

Using, the given identity $(x+y)(x^2-xy+y^2)=x^3+y^3$ ,

Substitute, the given values, we have,

$(x+y)(29-10)=133$

Simplify , we get,

$(x+y)(19)=133$

Divide both side by 19, we have,

$(x+y)=7$

Thus, the sum of two numbers is 7.

in the function y-1=1/2(x-6)^2 what effect does the number 6 have on the graph, as compared to the graph y=x^2

butalik [34]

Answer: The graph is shifted 6 units to the right.

Step-by-step explanation:

It is important to remember that:

When $f(x-k)$ , then the function is shifted "k" units to the right.

Knowing this and given the quadratic parent function $y=x^2$ and the function $y-1=\frac{1}{2}(x-6)^2$ , you can observe that one of the transformations is the following:

$f(x-k)$

Where:

$k=6$

Therefore, you can notice that the effect is:

The graph is shifted 6 units to the right.
