The sum of two positive integers, x and y, is not more than 40. The difference of the two integers is at least 20. Chaneece choo

Butoxors [25]

Answer:

The value of x lies between 20 and 40 and value of y lies between -20 and 10

Step-by-step explanation:

We are given that

$y\leq 40-x$ ....(1)

$y\leq x-20$ ...(2)

First we convert inequality equation into equality equation to find the solution of the given system of inequality equation.

Therefore, we can write as

$y=-x+40$ ...(3)

$y=x-20$ ...(4)

Adding equation (3) and (4) we get

$2y=20$

$y=10$

Substitute y=10 in equation (3) we get

$10=40-x$

$x=40-10=30$

(30,10) is the intersect point of two equation.

Put x=0 in equation (3)

$y=40$

Substitute y=0 in equation (3)

$x=40$

Substitute x=0 in equation (4)

$y=-20$

Substitute y=0 in equation (4)

$x=20$

Substitute x=0 and y=40 and in equation (1)

$40\leq 40$

Hence, the equation is true.Therefore, the shaded region below the line.

Substitute x=0 and y=-20 in equation (2)

$-20\leq -20$

The equation is true. Hence, the shaded region is below the line.

Hence, the value of x lies between 20 and 40 and value of y lies between -20 and 10.

The number of customers in a grocery store is modeled by the function y -X? + 10x + 50, where y is

vova2212 [387]

Using the vertex of the quadratic function, it is found that:

a) The maximum number of customers in the store is at 12 P.M.

b) 75 customers are in the store at this time.

The number of customers in x hours after 7 AM is given by:

$y = -x^2 + 10x + 50$

Which is a quadratic equation with coefficients $a = -1, b = 10, c = 50$

Item a:

The maximum value, considering that a < 0, happens at:

$x_v = -\frac{b}{2a}$

Hence:

$x_v = -\frac{10}{2(-1)} = 5$

5 hours after 7 A.M, hence, the maximum number of customers in the store is at 12 P.M.

Item b:

The value is y(5), hence:

$y(5) = -(5)^2 + 10(5) + 50 = 75$

75 customers are in the store at this time.

2)306 in³

3)210in³

Step-by-step explanation:

1) r = 5in h = 12in

5 * 12 * 3.14

2) L = 3 W = 8.5 H = 12

3 * 8.5 * 12

3) $\frac{1}{2}$ ( B = 5 W = 7 H = 12)
